You may have heard of Soo In Chae's work under "Bakoon" which was a collaboration between Soo In (founder of Enleum) and Akira Nagai. </span></div><div class="separator" style="clear: both; text-align: justify;"><br /></div><div class="separator" style="clear: both; text-align: justify;"><span style="font-family: arial;"><b>Description</b></span></div><div class="separator" style="clear: both; text-align: justify;"><span style="font-family: arial;"><br /></span></div><div class="separator" style="clear: both; text-align: justify;"><span style="font-family: arial;">The HPA-23RM (the "R" and "M" being shorthand for Reference and Mobile) is a unique headphone amplifier with two different amplification circuits - a voltage, and current output stage. The voltage stage is a MOSFET output stage based on a simplified version of the JET2 bias circuit seen in the AMP-23R. The current output stage is derived from the HPA-21's bipolar transistor circuit. While this device is not something you would lug around on a regular basis, it is portable enough to be moved around and can be used on-the-go thanks to its built-in battery. Similar in size to a paper-backed novel, the Enleum measures 116mm x 164.5mm x 22mm and weighs 750 grams.</span></div><div class="separator" style="clear: both; text-align: justify;"><span style="font-family: arial;"><br /></span></div><div class="separator" style="clear: both; text-align: justify;"><span style="font-family: arial;">On the front panel, a toggle switch selects gain, while a recessed rotary knob functions as both a volume control and power switch. A 3.5mm socket is mated to the voltage stage, while a 1/4 inch socket is used for the current output stage. A row of LED lights indicate charge status, battery life and operation. </span></div><div class="separator" style="clear: both; text-align: justify;"><span style="font-family: arial;"><br /></span></div><div class="separator" style="clear: both; text-align: justify;"><span style="font-family: arial;">The inputs are located on the rear panel, with a USB-C socket used for charging, and a pair of RCA sockets and a 3.5mm socket used for the input signal. There is no selector switch, so only one input may be used at a time. If the 3.5mm socket is in use, this is given priority over the RCA input. </span></div><div class="separator" style="clear: both; text-align: justify;"><br /></div><div class="separator" style="clear: both; text-align: justify;"><span style="font-family: arial;">The current-output stage is capable of 1W of power, and half of that into the voltage output (into a 30 ohm load). </span></div><div class="separator" style="clear: both; text-align: center;"><br /></div><div class="separator" style="clear: both; text-align: center;"> <div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj1dGcFssJ9bAf6LiO0p3efwtzWlGItM4DgECttCPw9se78MUs-49QDwHA7DnBvy7djGvRVbOaJTtM1ywwxfsYS3n14jCt_JPvfBiFcFe2NYNDch-pPBKOP7c0iFPWYpjMlyQJVJwNFubd9yxsntZi5HaV_RH0gRMzxB_hUsb2567ovc_Iz-yj1T6_Y_bc/s4080/PXL_20240316_031652028.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3072" data-original-width="4080" height="482" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj1dGcFssJ9bAf6LiO0p3efwtzWlGItM4DgECttCPw9se78MUs-49QDwHA7DnBvy7djGvRVbOaJTtM1ywwxfsYS3n14jCt_JPvfBiFcFe2NYNDch-pPBKOP7c0iFPWYpjMlyQJVJwNFubd9yxsntZi5HaV_RH0gRMzxB_hUsb2567ovc_Iz-yj1T6_Y_bc/w640-h482/PXL_20240316_031652028.jpg" width="640" /></a></div><br /></div><div class="separator" style="clear: both; text-align: justify;"><span style="font-family: arial;"><b>In operation</b></span></div><div class="separator" style="clear: both; text-align: justify;"><span style="font-family: arial;"><b><br /></b></span></div><div class="separator" style="clear: both; text-align: justify;"><span style="font-family: arial;">Rotating the volume knob from its resting position to about 8 o'clock brings the unit into standby mode. The LEDs light up to indicate the battery level. The HPA-23RM uses a discrete resistor relay network to control the volume and a</span><span style="font-family: arial;">dvancing the knob further unmutes the unit , with an audible click as you move between each volume level. The manual advises you to bring the volume knob back to the standby position before plugging and unplugging headphones to avoid damage to the unit. </span></div><div class="separator" style="clear: both; text-align: justify;"><span style="font-family: arial;"><br /></span></div><div class="separator" style="clear: both; text-align: justify;"><span style="font-family: arial;">The unit is specified to operate for up to 5 hours of use in voltage output mode, and 3.5 hours in current output mode, which matched my user experience. Thankfully, the HPA-23RM can be charged while in use.</span></div><div class="separator" style="clear: both; text-align: justify;"><span style="font-family: arial;"><br /></span></div><div class="separator" style="clear: both; text-align: justify;"><span style="font-family: arial;"><b>Sound Quality</b></span></div><div class="separator" style="clear: both; text-align: justify;"><span style="font-family: arial;"><br /></span></div><div class="separator" style="clear: both; text-align: justify;"><span style="font-family: arial;">Enleum recommends as a starting point that the voltage output be used with IEMs / headphones that are sensitive, or have a varying impedance curve, while the current output be used with headphones that have a flat impedance curve such as planar headphones. This is of course not a hard rule, and Enleum does encourage you to experiment. Matching a headphone with a varying impedance curve with the current output does result in a frequency response that tracks the impedance curve, which could be either a good or bad thing depending on your objective. For example, the Sennheiser HD8xx has an impedance peak at about 100 Hz and a falling impedance in the high-frequencies. Listening to these headphones through the current output gives you added bass and attenuated high-frequencies. </span><span style="font-family: arial;"> </span></div><div class="separator" style="clear: both; text-align: justify;"><span style="font-family: arial;"><b><br /></b></span></div><div class="separator" style="clear: both; text-align: justify;"><span style="font-family: arial;">To be continued ...</span></div><div class="separator" style="clear: both; text-align: center;"><br /></div><br /><p></p>Eric Tehhttp://www.blogger.com/profile/05157135145227727200noreply@blogger.com0tag:blogger.com,1999:blog-684396141123606281.post-27568672465836956762024-03-15T19:42:00.000-07:002024-03-15T19:42:38.177-07:00NAD Masters M66 and Dali Epikore 11 - Singapore Launch<p><span style="font-family: arial;"><b>2 March 2024</b></span></p><p><span style="font-family: arial;"><b>Introduction</b></span></p><p><span style="font-family: arial;"></span></p><div class="separator" style="clear: both; text-align: center;"><span style="font-family: arial;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj_Ce8dF_MeDQ1NmSkVfR-1qqM0SKIyX7NnMyvPlq2KEsdapxhREHr1gtd_S2FwMLuWSPbCp3PuIzy3npULZk860AZiQf_joJhsDFnlvKYEtD04afQaYJ-pv3A4afbD_j0QbUxsBiJqnCE9TJcR4tBuQtYXkvF_ZbWYHyLSirWpoNJ2SmgHtpOhheIKVNc/s1200/system2.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="904" data-original-width="1200" height="482" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj_Ce8dF_MeDQ1NmSkVfR-1qqM0SKIyX7NnMyvPlq2KEsdapxhREHr1gtd_S2FwMLuWSPbCp3PuIzy3npULZk860AZiQf_joJhsDFnlvKYEtD04afQaYJ-pv3A4afbD_j0QbUxsBiJqnCE9TJcR4tBuQtYXkvF_ZbWYHyLSirWpoNJ2SmgHtpOhheIKVNc/w640-h482/system2.jpg" width="640" /></a></span></div><span style="font-family: arial;"><br /><b><br /></b></span><p></p><p><span style="font-family: arial;">Lenbrook Asia launched the NAD Masters M66 flagship streamer/DAC-preamp and the Dali Epikore 11 speakers today.</span></p><p><span style="font-family: arial;">The Masters M66 is a BluOS streamer and DAC-preamp that features rich functionality and the latest technology in a single box.

It had astounding dynamics and the genuine ability to pressurise the large showroom space with deep and chest-thumping bass. I was pleasantly surprised that it was equally adept at reproducing small-scale works with finesse and delicacy. </span></p><p><span style="font-family: arial;">Soundstaging was outstanding with careful placement of instruments and voices, with good width, depth and height too. Music was reproduced without harshness or grain, even at very high volumes. </span></p><p><span style="font-family: arial;">Tonally, the system is on the laidback end of the spectrum although there is plenty of detail in the high-frequencies to balance things out. Although these speakers could probably blow your roof off, they will appeal more to listeners who want a comfortable and non-fatiguing presentation.</span></p><p><span style="font-family: arial;">Lenbrook also demonstrated the effect of DIRAC as they toggled it on-and-off. The music sounded harsh and the soundstaging lost a great degree of precision sans DIRAC. Having covered DIRAC in the NAD C 3050 LE amplifier, this did not come as a surprise to me. </span></p><p><span style="font-family: arial;"><b>Conclusion</b></span></p><p><span style="font-family: arial;">This is a system well-worth checking out if you are looking out for a modern and high-end solution to your audio needs. The Masters M66 showed great promise, and the possibility of future software upgrades, or modular upgrades is an attractive proposition. </span></p><p><span style="font-family: arial;"><br /></span></p><p><span style="font-family: arial;"><br /></span></p><p><span style="font-family: arial;"> </span></p><p><br /></p><p><span style="font-family: arial;"> </span></p>Eric Tehhttp://www.blogger.com/profile/05157135145227727200noreply@blogger.com0tag:blogger.com,1999:blog-684396141123606281.post-45759304708016325562024-03-14T05:04:00.000-07:002024-03-14T05:04:57.881-07:00News - Introducing Vivid Audio Moya M1<p><b><span style="font-family: arial;">14 March 2024</span></b></p><p><span style="font-family: arial;"><b>Press release</b></span></p><p><span style="font-family: arial;"></span></p><div class="separator" style="clear: both; text-align: center;"><span style="font-family: arial;"><iframe allowfullscreen='allowfullscreen' webkitallowfullscreen='webkitallowfullscreen' mozallowfullscreen='mozallowfullscreen' width='320' height='266' src='https://www.blogger.com/video.g?token=AD6v5dw71gWmtNd8UEuYzZea-HCQGG4IG33StaN06yPkcPgMONuROPGbDpQ0g_NQV6SXzfxqp0EGy6aWilCTxwPoIA' class='b-hbp-video b-uploaded' frameborder='0'></iframe></span></div><span style="font-family: arial;"><br /><b><br /></b></span><p></p><p><span style="font-family: arial;"></span></p><div class="separator" style="clear: both; text-align: center;"><span style="font-family: arial;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiufUUe7hENQ1goYdV3C8mj-xdSwcX6GgUcHBCSkZGIWBuWYS-Gi2Ocq3ZrTjFBjkTPetUIwTxrGzZa1QXRrCLjaZ-znQYNzgVvB35QKV9DHJxS5e4L03i4qVaS9qsuY_j7iY3PnfmEVM5ZR0KUY1x0KZ035Q735q36nGo7ltZtRp616zNx9bQ-ufbWk4k/s3089/Vivid_Audio-Moya-M1_interior-01.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1190" data-original-width="3089" height="247" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiufUUe7hENQ1goYdV3C8mj-xdSwcX6GgUcHBCSkZGIWBuWYS-Gi2Ocq3ZrTjFBjkTPetUIwTxrGzZa1QXRrCLjaZ-znQYNzgVvB35QKV9DHJxS5e4L03i4qVaS9qsuY_j7iY3PnfmEVM5ZR0KUY1x0KZ035Q735q36nGo7ltZtRp616zNx9bQ-ufbWk4k/w640-h247/Vivid_Audio-Moya-M1_interior-01.jpg" width="640" /></a></span></div><span style="font-family: arial;"><br /><b><br /></b></span><p></p><p><span style="font-family: arial;"><b>Introducing Vivid Audio Moya M1</b></span></p><p><span style="font-family: arial;"><b>A NEW SUMMIT IN LOUDSPEAKER ENGINEERING</b></span></p><p><span style="font-size: x-small;"><span style="font-family: arial;">For over 20 years, Vivid Audio has developed ground-breaking loudspeakers to consistent critical acclaim.

From the very start, the pair set out </span><span style="font-family: arial;">to build loudspeakers that ‘present the original recording, as clearly and faithfully as possible’.</span></span></p><p><span style="font-size: x-small;"><span style="font-family: arial;">From the launch of the first Vivid Audio model – the Oval B1 – in 2004, they have rigorously pursued this vision and now </span><span style="font-family: arial;">offer an extensive range of models, from the Kaya C35 to the new flagship, Moya M1.</span></span></p><p><span style="font-size: x-small;"><span style="font-family: arial;">Guttentag, a trained engineer, brought extensive experience in the retail, acoustic consultancy and distribution fields; Dickie </span><span style="font-family: arial;">was an established loudspeaker designer with a long and illustrious career.</span></span></p><p><span style="font-size: x-small;"><span style="font-family: arial;">While working for British loudspeaker manufacturers, Bowers and Wilkins, Laurence Dickie pioneered the “Matrix” loudspeaker </span><span style="font-family: arial;">bracing system that is still used in the majority of loudspeakers today. He was also behind the development of </span><span style="font-family: arial;">numerous iconic designs, including the B&W Nautilus, considered one of the finest loudspeakers in the world.</span></span></p><p><span style="font-size: x-small;"><span style="font-family: arial;">The Nautilus introduced the concept of tapered tubes to the audio world.

These is a Bluetooth input, tone controls, a preamp output and a headphone socket. </span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: Arial, sans-serif; font-size: 11pt; font-variant-alternates: normal; font-variant-east-asian: normal; font-variant-numeric: normal; font-variant-position: normal; vertical-align: baseline; white-space-collapse: preserve;">Physically and visually, the P3 matches the V3 having the same footprint and design. The 7-pin 5654W tubes stick out from the top and hence the P3 needs to be placed on top if you are stacking them. According to Fosi Audio, the tube plates are run at 54V DC. The P3 was originally announced as using 6Ж2П/5725 tubes, but you can switch to those as a substitute. Both tubes were not specifically designed for audio and are available quite cheaply, even for premium vintage brands. This would make tube rolling a lot easier on your wallet. </span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: Arial, sans-serif; font-size: 11pt; font-variant-alternates: normal; font-variant-east-asian: normal; font-variant-numeric: normal; font-variant-position: normal; vertical-align: baseline; white-space-collapse: preserve;">Three knobs are placed on the front panel, with the larger volume knob in the center, and the bass and treble knobs on the right and left respectively. I found this a bit odd, as it’s more common for the bass knob to be on the left side. A 3.5mm headphone socket is placed on the left side of the panel, while a 3-position rocker switch on the right switches the unit off, or toggles between the Bluetooth or RCA input. Plugging your headphones into the 3.5mm socket automatically mutes output to your speakers. </span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: Arial, sans-serif; font-size: 11pt; font-variant-alternates: normal; font-variant-east-asian: normal; font-variant-numeric: normal; font-variant-position: normal; vertical-align: baseline; white-space-collapse: preserve;">The tone-control knobs have a physical center detent at 12 o’clock so that you know whether you are boosting or reducing the relevant frequencies, which is useful if you want to bypass them altogether. </span></p><div><span><br /></span></div><div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhtsxdMwY1nSgMfp6LTTchU53knRsF1FlT9IRWkEhKaQHdaX3qfowKXzyGwIsunSeLO-jq7k5rNYfp53uDW0dHCoLzm369p9oJH4sgbL2VH_n23SOAcRSssY9CpCf6Ox4I17sttrIAJnxFKGcmrDcZM4dKti2TJPXwB_oDsKM8jqU-g-LbBnYeJrOde3Vk/s1200/IMG_7951.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="800" data-original-width="1200" height="426" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhtsxdMwY1nSgMfp6LTTchU53knRsF1FlT9IRWkEhKaQHdaX3qfowKXzyGwIsunSeLO-jq7k5rNYfp53uDW0dHCoLzm369p9oJH4sgbL2VH_n23SOAcRSssY9CpCf6Ox4I17sttrIAJnxFKGcmrDcZM4dKti2TJPXwB_oDsKM8jqU-g-LbBnYeJrOde3Vk/w640-h426/IMG_7951.JPG" width="640" /></a></div><br /><span><br /></span></div><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: Arial, sans-serif; font-size: 11pt; font-variant-alternates: normal; font-variant-east-asian: normal; font-variant-numeric: normal; font-variant-position: normal; vertical-align: baseline; white-space-collapse: preserve;">A single pair of RCA input and output sockets are placed on the rear panel, together with the Bluetooth antenna, a small button to reset the Bluetooth pairing, and a DC power inlet for the external 12V power supply. If you want to experiment with power supplies, do take note that the power inlet uses a 5.5/2.5 barrel. I think Fosi Audio should seriously consider adding a second set of line-level inputs - it’s a bit odd for a preamp to only have a single input!</span></p><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: Arial, sans-serif; font-size: 11pt; font-variant-alternates: normal; font-variant-east-asian: normal; font-variant-numeric: normal; font-variant-position: normal; vertical-align: baseline; white-space-collapse: preserve;"><br /></span></p><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEib_UzJYQEd0fiMuVipW7NypVTOR1DeLvORFHyf7T_tWONB6uUVvqRR2ZNYWHkcXInIyow6eWfAvDYj59FWrePInQZnMFPGa7xqW7tmT2DJdS0PcZWv3ASIksDA9AJS_qqA3SzzLofPtFKsuzZ0P0le65qfJhsNTzoq5St_M3LBkTBTHo6oqzyCM5uJBdI/s1200/IMG_7955.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="800" data-original-width="1200" height="426" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEib_UzJYQEd0fiMuVipW7NypVTOR1DeLvORFHyf7T_tWONB6uUVvqRR2ZNYWHkcXInIyow6eWfAvDYj59FWrePInQZnMFPGa7xqW7tmT2DJdS0PcZWv3ASIksDA9AJS_qqA3SzzLofPtFKsuzZ0P0le65qfJhsNTzoq5St_M3LBkTBTHo6oqzyCM5uJBdI/w640-h426/IMG_7955.JPG" width="640" /></a></div><br /><span style="font-family: Arial, sans-serif; font-size: 11pt; font-variant-alternates: normal; font-variant-east-asian: normal; font-variant-numeric: normal; font-variant-position: normal; vertical-align: baseline; white-space-collapse: preserve;"><br /></span><p></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: Arial, sans-serif; font-size: 11pt; font-variant-alternates: normal; font-variant-east-asian: normal; font-variant-numeric: normal; font-variant-position: normal; vertical-align: baseline; white-space-collapse: preserve;">The headphone output is specified to work with loads between 16-300 ohms, with 250mw of power into 16 ohms and 20mw of power into 300 ohms. </span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: Arial, sans-serif; font-size: 11pt; font-variant-alternates: normal; font-variant-east-asian: normal; font-variant-numeric: normal; font-variant-position: normal; vertical-align: baseline; white-space-collapse: preserve;">The Bluetooth input is based on a Qualcomm QCC3031 chipset that supports Bluetooth 5.1 and </span><span style="color: #353535; font-family: Roboto, sans-serif; font-size: 10.5pt; font-variant-alternates: normal; font-variant-east-asian: normal; font-variant-numeric: normal; font-variant-position: normal; vertical-align: baseline; white-space-collapse: preserve;">SBC/AAC/aptX/aptX HD/aptX LL</span><span style="font-family: Arial, sans-serif; font-size: 11pt; font-variant-alternates: normal; font-variant-east-asian: normal; font-variant-numeric: normal; font-variant-position: normal; vertical-align: baseline; white-space-collapse: preserve;"> codecs.</span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: Arial, sans-serif; font-size: 11pt; font-variant-alternates: normal; font-variant-east-asian: normal; font-variant-numeric: normal; font-variant-position: normal; font-weight: 700; vertical-align: baseline; white-space-collapse: preserve;">In Use</span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: Arial, sans-serif; font-size: 11pt; font-variant-alternates: normal; font-variant-east-asian: normal; font-variant-numeric: normal; font-variant-position: normal; vertical-align: baseline; white-space-collapse: preserve;">Out of the box, you will need to install the tubes, hook-up the power supply and other necessary connections before you are good to go. Installation of the tube is tricky as the opening is small, and you can’t see whether the tube pins are aligned with the socket. If your tube pins are bent, straightening them out first makes insertion a lot easier. Fosi has since uploaded a video showing that the decorative ring around the tube socket can be removed to allow easier swapping of tubes. They are really tight, so I recommend you use a non-slip pad to grip the ring before rotating them counter-clockwise.

However, I still advise that you follow the regular procedure of switching on the P3 first, before powering on the V3 and following the reverse order when powering down the system. </span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: Arial, sans-serif; font-size: 11pt; font-variant-alternates: normal; font-variant-east-asian: normal; font-variant-numeric: normal; font-variant-position: normal; vertical-align: baseline; white-space-collapse: preserve;">Switching on the P3 activates cyan LED lights beneath the tubes which is a nice contrast to the orange glow from the tube filaments. The P3 runs very cool for a tube preamp. In fact, the V3 heats up a lot more. </span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: Arial, sans-serif; font-size: 11pt; font-variant-alternates: normal; font-variant-east-asian: normal; font-variant-numeric: normal; font-variant-position: normal; vertical-align: baseline; white-space-collapse: preserve;">There was noticeable hum from my speakers using the supplied switched-mode power supply, but this was reduced significantly when I substituted the stock power supply with an aftermarket linear power supply. Even with the stock power supply, the hum was only noticeable during silent passages, and with my ears about 30 cm from the speaker. I don’t think it would be an issue for most people unless they have very sensitive speakers. I did not hear any noise through the headphone jack though. </span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: Arial, sans-serif; font-size: 11pt; font-variant-alternates: normal; font-variant-east-asian: normal; font-variant-numeric: normal; font-variant-position: normal; vertical-align: baseline; white-space-collapse: preserve;">The Bluetooth connected easily to my Google Pixel 7 Pro phone, and the sound quality was quite impressive. Watching Netflix and YouTube videos on my phone showed very little latency and I did not notice any lip sync issues.</span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: Arial, sans-serif; font-size: 11pt; font-variant-alternates: normal; font-variant-east-asian: normal; font-variant-numeric: normal; font-variant-position: normal; vertical-align: baseline; white-space-collapse: preserve;">Connecting headphones or IEMs to the P3 is going to be a hit-or-miss affair though. With my Letshuoer S12 Pro IEMs (16 ohm impedance), the volume knob was far too sensitive, with noticeable channel mismatch at low to mid-level volumes. Using headphones like my E-Mu Teak (50 ohm) and Beyer DT880 (250 ohm version), sound quality was fine although the bass was a bit flabby on the Beyer. The sound was pretty decent on the E-Mu but I would consider the headphone socket as more of a convenience than a substitute for a proper headphone amplifier.</span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: Arial, sans-serif; font-size: 11pt; font-variant-alternates: normal; font-variant-east-asian: normal; font-variant-numeric: normal; font-variant-position: normal; vertical-align: baseline; white-space-collapse: preserve;">The preamp output on the P3 is variable and changes with both the volume and tone control knobs. This is unlike the preamp output on V3 which is fixed in level (and which should have been labelled as a line-level output instead). This makes it a lot easier to connect the P3 to either a powered subwoofer or active speakers.</span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: Arial, sans-serif; font-size: 11pt; font-variant-alternates: normal; font-variant-east-asian: normal; font-variant-numeric: normal; font-variant-position: normal; vertical-align: baseline; white-space-collapse: preserve;">If you are familiar with the Fosi Audio range, you could be asking yourself whether the BT20A Pro is the simpler solution, since it has the combined functionality of the P3 and V3. If you hate the idea of tubes, and don’t prioritise sound quality, the BT20A Pro is a feasible option. Sonically though, the V3 or the P3/V3 combo is superior to the BT20A Pro. </span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: Arial, sans-serif; font-size: 11pt; font-variant-alternates: normal; font-variant-east-asian: normal; font-variant-numeric: normal; font-variant-position: normal; font-weight: 700; vertical-align: baseline; white-space-collapse: preserve;">Sound Quality</span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: Arial, sans-serif; font-size: 11pt; font-variant-alternates: normal; font-variant-east-asian: normal; font-variant-numeric: normal; font-variant-position: normal; vertical-align: baseline; white-space-collapse: preserve;">I was worried that the P3 would disappoint. A low-cost tube preamp, operating at a relatively low plate voltage of 54V is hardly a recipe for sonic bliss. Looking at the tube curves for the 5654W tubes, there is a possibility that we may not even be past the “knee” of the curves. As we don’t know the grid voltage used, your guess is as good as mine. </span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: Arial, sans-serif; font-size: 11pt; font-variant-alternates: normal; font-variant-east-asian: normal; font-variant-numeric: normal; font-variant-position: normal; vertical-align: baseline; white-space-collapse: preserve;">I set up the V3 with my Elac Reference DBR62 speakers and a Geschelli Labs J2 DAC. I then played the same tracks with the P3 connected to the V3. The V3’s volume knob was turned to the maximum, and the level was set using the P3’s volume knob. </span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: Arial, sans-serif; font-size: 11pt; font-variant-alternates: normal; font-variant-east-asian: normal; font-variant-numeric: normal; font-variant-position: normal; vertical-align: baseline; white-space-collapse: preserve;">With the V3, my usual listening level was with the volume knob at about 11 o’clock. The P3 was set at about 9 o’clock. My guess is that the P3 has some modest gain, which is useful if your source is not loud enough. </span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: Arial, sans-serif; font-size: 11pt; font-variant-alternates: normal; font-variant-east-asian: normal; font-variant-numeric: normal; font-variant-position: normal; vertical-align: baseline; white-space-collapse: preserve;">On </span><span style="font-family: Arial, sans-serif; font-size: 11pt; font-style: italic; font-variant-alternates: normal; font-variant-east-asian: normal; font-variant-numeric: normal; font-variant-position: normal; vertical-align: baseline; white-space-collapse: preserve;">Feels So Good </span><span style="font-family: Arial, sans-serif; font-size: 11pt; font-variant-alternates: normal; font-variant-east-asian: normal; font-variant-numeric: normal; font-variant-position: normal; vertical-align: baseline; white-space-collapse: preserve;">by Chuck Mangione, the Flugelhorn had more vibrancy and presence with the P3. Bass lines gained impact and warmth. With just the V3, images were precise, but small and flat. Listening to 搜神記, Joey Yung’s voice was projected forward into the soundstage, lending a more intimate feel. With the V3, her voice was reproduced with a clean but flatter presentation. With the P3, her voice gained texture, and more emotion. </span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: Arial, sans-serif; font-size: 11pt; font-variant-alternates: normal; font-variant-east-asian: normal; font-variant-numeric: normal; font-variant-position: normal; vertical-align: baseline; white-space-collapse: preserve;">In terms of resolution, there was a subtle reduction of fine detail with the P3. This was to be expected, as a perfectly transparent preamp does not exist - with high-end preamps being expected to do less harm to the sound. The impact here was well worth the gains in other areas.</span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: Arial, sans-serif; font-size: 11pt; font-variant-alternates: normal; font-variant-east-asian: normal; font-variant-numeric: normal; font-variant-position: normal; vertical-align: baseline; white-space-collapse: preserve;">With the added midbass and midrange emphasis of the P3, the V3’s tonal balance moved to the warm side of neutral, with a perception of reduced treble energy. If you liked the brighter sound of the V3, you could of course use the tone controls to adjust this to your liking.</span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: Arial, sans-serif; font-size: 11pt; font-variant-alternates: normal; font-variant-east-asian: normal; font-variant-numeric: normal; font-variant-position: normal; vertical-align: baseline; white-space-collapse: preserve;">Post review, I also tried swapping the supplied 5654W tube for a Russian 6Ж2П. The Russian tube had a more linear and faster sound, at the expense of some midrange warmth and tube “glow”. Feel free to experiment to dial in the sound to your taste. </span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: Arial, sans-serif; font-size: 11pt; font-variant-alternates: normal; font-variant-east-asian: normal; font-variant-numeric: normal; font-variant-position: normal; font-weight: 700; vertical-align: baseline; white-space-collapse: preserve;">Conclusion</span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: Arial, sans-serif; font-size: 11pt; font-variant-alternates: normal; font-variant-east-asian: normal; font-variant-numeric: normal; font-variant-position: normal; vertical-align: baseline; white-space-collapse: preserve;">The P3 does what it should. It adds a pleasing tone to the V3 and addresses the issue of low gain too. Functionally, it fills in the gaps with a Bluetooth input, tone controls, a sub-woofer output and a headphone socket. </span></p><br /><p dir="ltr" style="line-height: 1.38; margin-bottom: 0pt; margin-top: 0pt;"><span style="font-family: Arial, sans-serif; font-size: 11pt; font-variant-alternates: normal; font-variant-east-asian: normal; font-variant-numeric: normal; font-variant-position: normal; vertical-align: baseline; white-space-collapse: preserve;">It made music more dynamic and life-like, with better tonal saturation and contrast.

I have a soft-spot for Gewurtztraminer and Riesling wines from Alsace, and these speakers (the Atalante 5) really impressed me. The SPEC Corporation RSA-M99 amplifier, SOtM stack and Cen.grand DAC played supporting roles. This system has a nice balance between organic warmth and detail.

Let's see what differences it brings to the table and whether it is a worthwhile upgrade for existing owners.</span></p><p><span style="font-family: arial;"><b>Description</b></span></p><p><span style="font-family: arial;">AGD builds their amplification stage into a glass envelope. While visually looking like a vacuum tube, they are solid-state devices. Some people have criticised AGD for this move. I found it visually appealing and an interesting talking point. With the introduction of new "tube" variants, AGD users are now able to upgrade their amplifiers without too much hassle. You could swap the "tube" in under 5 minutes per side, with most of the time spent undoing the hex screws to remove the protective cage for my Audion. This is not necessary, but gives my large fingers more room to work.</span></p><p><span style="font-family: arial;">The MkIII has been two years in the making, and AGD claims that the PWM stage and output filter have been redesigned with more advanced materials to deliver reduced distortion, lowered noise, higher bandwidth and faster response times. </span></p><p><span style="font-family: arial;">Class-D amplifiers require a low-pass filter to remove high-frequency circuit noise. Poor filtering designs result in a loss of high-frequency detail and air. According to AGD, the new filter results in flat response up to 60KHz. </span></p><p><span style="font-family: arial;">Output power has been increased to 250W at 4 ohms, and with the Audion, 200W at 4 ohms, due to limitation of the power supply of the Audion. In comparison, the original "tube" delivered 170W at 4 ohms.</span></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgnmBQ52p7hZuR4B_oXM-6nPHw4-ESchmpHeHYMMAGZl9CtA4qVCRzdIv8EHNu8EHL-d0bYg5BXPZxITi6gnp0QUGFwALHryK6L7tbJ4e-WvZV7mxAJGQaUsMs3Oov32TEuNEiFIfowrOlDAawCgxdOLzW18Ntt26jhs3dqqGzNqm_CbAKrJOFsQLnc7mQ/s4080/gantube1.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3072" data-original-width="4080" height="482" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgnmBQ52p7hZuR4B_oXM-6nPHw4-ESchmpHeHYMMAGZl9CtA4qVCRzdIv8EHNu8EHL-d0bYg5BXPZxITi6gnp0QUGFwALHryK6L7tbJ4e-WvZV7mxAJGQaUsMs3Oov32TEuNEiFIfowrOlDAawCgxdOLzW18Ntt26jhs3dqqGzNqm_CbAKrJOFsQLnc7mQ/w640-h482/gantube1.jpg" width="640" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiLg-galPy5691iW8qnj87UzLHTm0wiWAiEfmrCdnak-pNA_o2-Ia0PW2hbxYPCWlT6QYygct-jw58QUzR7DwYKqCg6bIQ1U_RLU1_SvuaCezZSAK09rySmYS1rcgrMQ3ZZScfksr6kTlDhAvob2chEsZnUF_PD0eUjyg5LZl6RQNfb3h3Ba9VhNggu0Xc/s4080/gantube2.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3072" data-original-width="4080" height="482" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiLg-galPy5691iW8qnj87UzLHTm0wiWAiEfmrCdnak-pNA_o2-Ia0PW2hbxYPCWlT6QYygct-jw58QUzR7DwYKqCg6bIQ1U_RLU1_SvuaCezZSAK09rySmYS1rcgrMQ3ZZScfksr6kTlDhAvob2chEsZnUF_PD0eUjyg5LZl6RQNfb3h3Ba9VhNggu0Xc/w640-h482/gantube2.jpg" width="640" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhSzeBNzNK3ADRaR3oSUdpK37NtVV_QzcQyBW8mhqf0mBUsRCd03LbzWFY0zJcoIUsHm80Pw3PsifibG7MUTpZwRmJX4xW0Caim0044gznOOhL-YIFpVuL_LBn443Ik0tYC5Fl0BDnuY4xI-53b9UBi_ZLSeNWlpA-PtNAQI2nbtQQNfTy0vA9Ni3rliUo/s4080/gantube3.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3072" data-original-width="4080" height="482" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhSzeBNzNK3ADRaR3oSUdpK37NtVV_QzcQyBW8mhqf0mBUsRCd03LbzWFY0zJcoIUsHm80Pw3PsifibG7MUTpZwRmJX4xW0Caim0044gznOOhL-YIFpVuL_LBn443Ik0tYC5Fl0BDnuY4xI-53b9UBi_ZLSeNWlpA-PtNAQI2nbtQQNfTy0vA9Ni3rliUo/w640-h482/gantube3.jpg" width="640" /></a></div><br /><span style="font-family: arial;"><b>Sound Quality</b></span><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;">Despite the increase in power rating, there is no noticeable increase in gain moving to the MkIII. </span><span style="font-family: arial;">The tonal balance remains close to the original, although there is a noticeable improvement in speed and neutrality. Bass quality immediately hits you with more power and articulation. Low frequency notes simply go deeper and with more detail. </span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;">On the midrange and high-frequencies, there is better vocal refinement, with an improved sense of air. Placement of voices and instruments are also improved, with better separation and dimensionality.</span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;">In tube terms, the improvements are similar to a change from KT88 to KT120 tubes. It's possible that some listeners may prefer the softer presentation of the original tube, but most would prefer the MkIII. </span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;"><b>Conclusion</b></span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;">The improvements are not on a subtle level and are on par with the sonic gains associated with moving one model up the product line. This makes the MkIII an easy recommendation for AGD customers. My only criticism is that AGD should make available a trade-in program for customers to help defray the cost of the upgrade. </span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;"><span style="font-size: x-small;"><b>Price : USD 1,500 per pair</b></span></span></div><div><p><span style="font-family: arial;"><br /></span></p><p><br /></p></div>Eric Tehhttp://www.blogger.com/profile/05157135145227727200noreply@blogger.com0tag:blogger.com,1999:blog-684396141123606281.post-25887400026384037252023-10-01T00:03:00.003-07:002023-10-01T00:11:47.061-07:00Hifistay Stella 80 Triple Swing Spike Shoes<p><b style="font-family: arial;">Introduction</b></p><p><span style="font-family: arial;">Hifistay is a Korean company that takes a novel approach to audio equipment support. The spike shoes on review here are part of the company's flagship "triple swing" line. The "triple swing" description refers to the three levels of ceramic ball bearings used within. No prizes for guessing how the "single swing" and "double swing" products compare. </span></p><p><span style="font-family: arial;">Conditioned by years of audiophile training to suppress unnecessary motion in speakers, the Hifistay will challenge your beliefs. A gentle push on your speaker will result in free motion as the cabinets move back and forth. The Stella 80 is highly efficient in converting vibrations to horizontal movement. As the product stood on my study desk, I saw the top spike-cup gently move. I realised that the barely felt vibration was coming from construction work about 50 meters down the road! </span></p><p></p><div class="separator" style="clear: both; text-align: center;"><iframe allowfullscreen="" class="BLOG_video_class" height="266" src="https://www.youtube.com/embed/gaPLyYZX6DI" width="320" youtube-src-id="gaPLyYZX6DI"></iframe></div><br /><div class="separator" style="clear: both; text-align: center;"><br /></div><p></p><p><span style="font-family: arial;"><b>Description</b></span></p><p><span style="font-family: arial;">The "Swing" line-up consists of various products ranging from 60 mm to 100 mm diameter spike shoes. The 60mm model is only available as a "double swing", while the 80 mm model is available in both "double swing" and "triple swing". The 100mm model is only available as a "triple swing" model. The choice of shoe would depend on the component, and weight supported. In the case of the 80 Triple Swing, it is described as being suitable for speakers, heavy amplifiers and your equipment rack. Rated load is a maximum of 120 kg/shoe, with a recommended load of 10-60 kg per shoe. </span><span style="font-family: arial;">The main body of the shoe unscrews from the base to provide height adjustment, which allows precise levelling.</span></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhAz2d3vucTLyJ_3qUU28aF_ImVZfY9sx4_4a9ttfWS8Am840taFBaQZkUMjfew0ODTQgDZOFLPFTu7Ck6XlQGv2Gpwes0T39YUwxqgPgCPmx7yyUpJi75q4BdHkq1SxBkUSYxo_b-IYozVqTruxLpapaEe5v3CIJe63Y3lt_BL6Ao2qgJ75lHJK931DS4/s1200/hifistay%20triple%20swing%20box.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="904" data-original-width="1200" height="482" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhAz2d3vucTLyJ_3qUU28aF_ImVZfY9sx4_4a9ttfWS8Am840taFBaQZkUMjfew0ODTQgDZOFLPFTu7Ck6XlQGv2Gpwes0T39YUwxqgPgCPmx7yyUpJi75q4BdHkq1SxBkUSYxo_b-IYozVqTruxLpapaEe5v3CIJe63Y3lt_BL6Ao2qgJ75lHJK931DS4/w640-h482/hifistay%20triple%20swing%20box.jpg" width="640" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgNBO8yOtchwOFSHI1iLLQrANPZ3F7ysGDvBj-zFH7JwvLTbVYR0fCIb5Y5_8ULlm81TlhatltICmr1Ix9fPZco4mH1jvaeySoqo-KytUCPWNCnA5nAykXhKQNfeeXdIwA3UqcPqnOTg2bnCoRabIIEX6YKZK-blhGHRW370fod-1BcznVd9wKxxyxKflg/s1200/hifistay%20triple%20swing.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="904" data-original-width="1200" height="482" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgNBO8yOtchwOFSHI1iLLQrANPZ3F7ysGDvBj-zFH7JwvLTbVYR0fCIb5Y5_8ULlm81TlhatltICmr1Ix9fPZco4mH1jvaeySoqo-KytUCPWNCnA5nAykXhKQNfeeXdIwA3UqcPqnOTg2bnCoRabIIEX6YKZK-blhGHRW370fod-1BcznVd9wKxxyxKflg/w640-h482/hifistay%20triple%20swing.jpg" width="640" /></a></div><br /><span style="font-family: arial;"><br /></span><p></p><p><span style="font-family: arial;"><b>Sound Quality</b> </span></p><p><span style="font-family: arial;">I tried the 80 Triple Swing with a Partington Super Dreadnought speaker stand (replacing Isoacoustics Gaia footers), and my Tannoy Kensington GR speakers (replacing the stocks spikes). In both cases, they rested on hardwood parquet flooring. </span><span style="font-family: arial;">Once installed, the speakers rock gently as they are pushed. Audiophiles being fixated with non-movement will find this disconcerting initially.</span></p><p></p><div class="separator" style="clear: both; text-align: center;"><iframe allowfullscreen="" class="BLOG_video_class" height="266" src="https://www.youtube.com/embed/mkIuJ0-ld0c" width="320" youtube-src-id="mkIuJ0-ld0c"></iframe></div><br /><span style="font-family: arial;"><br /></span><p></p><p><span style="font-family: arial;">In the case of the Partington Super Dreadnought speakers stands (with Elac Uni-Fi Reference UBR62 speakers perched on top), there is a useful cleaning-up, and tightening of the music across the frequency range.</span></p><p><span style="font-family: arial;">Moving on to the Tannoys is when things really got interesting. The Tannoys have always sounded dynamic and fast in my setup, albeit with a tendency to sound a bit bright and bass light. I attributed this to a lack of power, although the Tannoys are easy to drive on paper at 93db sensitivity / 8 ohms. Nevertheless, I got the best bass using powerful amplifiers like the Apollon 1ET400A (227W) instead of low-powered tube amps.</span></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgO76ZbxKwhjeCg3YEnakIubCAivZGhCvYg_fuaTkw3sTsi_GwhyphenhyphenuSZ9LoKopBfdy_-ZkwLt9b3ZwHNRc_nSw7HYP3UV4TYBxxNM2nyxCn_sLiY-ptHVesgjfT9gQVUQyWWK23S-CzWGZt87waz1bZD8NjtbYNobGASAvCbwb7VC12eUOtY3g6DIdOoeZI/s1200/hifistay_tannoy.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="904" data-original-width="1200" height="482" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgO76ZbxKwhjeCg3YEnakIubCAivZGhCvYg_fuaTkw3sTsi_GwhyphenhyphenuSZ9LoKopBfdy_-ZkwLt9b3ZwHNRc_nSw7HYP3UV4TYBxxNM2nyxCn_sLiY-ptHVesgjfT9gQVUQyWWK23S-CzWGZt87waz1bZD8NjtbYNobGASAvCbwb7VC12eUOtY3g6DIdOoeZI/w640-h482/hifistay_tannoy.jpg" width="640" /></a></div><br /><span style="font-family: arial;"><br /></span><p></p><p><span style="font-family: arial;">With the Triple Swing installed, the increase in tight and deep bass was remarkable, almost as if I had upgraded my speakers. A dramatic improvement across the rest of the frequency range resulted in improved detail retrieval and focus. As a result, the soundstaging become pinpoint with very deep and distinct layering. High-frequencies were also improved, with a more defined leading edge and decay. </span></p><p><span style="font-family: arial;">Unlike some other ball-bearing products that I have tried, the Triple Swing does not impact musicality nor coherency. It is far from sounding bright, and instead imparts a fluidity to music that is pleasing. There is no spotlighting of specific frequencies, nor aberrations in the tempo of music. Somehow, this product really manages to deliver the best of both worlds - reproducing plenty of details and improving speed, while retaining naturalness and musicality. </span></p><p><span style="font-family: arial;">As a forewarning, I anticipate that this product will shift the tonal balance of your system. In particular, the increase in bass power will be a boon to some, and a bane to others. Judicious tweaking and adjustments post-installation will be required to maximise performance. </span></p><p><span style="font-family: arial;"><b>Conclusion</b></span></p><p><span style="font-family: arial;">This product is expensive, and makes sense only in high-end setups. Nevertheless, the improvements made are worthwhile in my personal opinion.

The DAC205 offers only a Toslink and coaxial input, making the DAC204 the unit of choice if you require a USB input. </span><span style="font-family: arial;">Based on an oversampling sigma-delta D/A convertor, four paralleled D/A convertors are used per channel for superior signal-to-noise performance. High jitter suppression is claimed by virtue of several signal re-clocking schemes.</span></p><p><span style="font-family: arial;">The USB input supports sampling frequencies of up to 384kHz and DSD64/128 (sampling frequencies of 352.8 and 384kHz are downsampled to half the original frequency). Two front panel toggle switches convert DSD signals to PCM at either 88.2kHz or 176.4kHz sampling rate and 16 or 24-bit word-length. The coaxial and Toslink inputs accept signals of up to 192kHz. </span></p><p><span style="font-family: arial;">The flexibility offered by the DAC204 is tremendous. Three digital outputs (coaxial, BNC and AES/EBU) allow digital signals to be routed to another DAC or digital recording device. For example, the DAC204 could be used with legacy DACs that neither have a USB input, nor DSD compatibility. </span></p><p><span style="font-family: arial;">Turning to the analog outputs, both single-ended and balanced outputs are available, with four selectable output voltages (0.23V to 7.5V for the balanced output, and 0.115V to 3.75V for the single-ended output). This allows the DAC204 to be adjusted based on the gain structure of your system. The higher voltage settings would be especially useful for passive preamp users. </span></p><p><span style="font-family: arial;">The power supply is off-board, with a medical-grade switched-mode power supplied. The DAC204 accepts a supply voltage between 6 to 9V DC, with a current requirement of 1050 ma at 6V or 700 ma at 9V. Weiss will also sell you the PSU101 universal power supply if you wish to upgrade the performance of the DAC204. Just be warned though, it's as expensive as the DAC itself!</span></p><p><span style="font-family: arial;"><b>In use</b></span></p><p><span style="font-family: arial;"></span></p><p><span style="font-family: arial;">The Singapore distributor for Weiss kindly included a Plixir Elite 6V-6A power supply and Statement DC cable to try out with the DAC204. I used both the Plixir and the stock power supply during my evaluation. </span></p><p><span style="font-family: arial;">I hooked up an old CD player to the coaxial input to run-in the unit. None of the sampling frequency LEDs lit up although music flowed. Reading the manual again, I realised that the LEDs only light up when using the USB input. Apart from this initial scare, the DAC204 performed without any issues. </span></p><p><span style="font-family: arial;"><b>Sound Quality</b></span></p><p><span style="font-family: arial;">With the Plixir, the DAC204 impressed with a highly detailed and cohesive sonic performance. The first thing that strikes you is how music flowed without any particular frequency calling undue attention. </span></p><p><span style="font-family: arial;">Bass was tight and impactful and had good speed and tempo. </span><span style="font-family: arial;">Vocals had a mild laidback quality that provided some warmth to the human voice. High frequencies were reproduced with a clean and crisp edge. The Weiss managed to strike a perfect balance - with a detailed and grain-free midrange and good highs without sounding bright or strident. </span></p><p><span style="font-family: arial;">Readers to this point would be wondering what made the Weiss special compared to competition? In my view, the DAC204 was able to convey a superior sense of dimensionality and realism - with clear illumination of the acoustic space around each voice and instrument in the recording. I associate this particular quality with high-end DACs which is high praise indeed for the Weiss. </span></p><p><span style="font-family: arial;">The subtly warm tone and lack of harshness allowed for many hours of fatigue-free listening. Despite the professional audio heritage, the Weiss struck me as a musical device - I spent most of my time enjoying the music instead of trying to dissect the recording. </span></p><p><span style="font-family: arial;">Swapping out of the Plixir for the stock power supply greatly diminished the performance of the Weiss. Apart from losing impact and power in the low-frequency region, the drop in resolution and separation was obvious. </span></p><p><span style="font-family: arial;"><b>Conclusion</b></span></p><p><span style="font-family: arial;">Sonically compelling with the Plixir power supply, the Weiss offers great flexibility in a small format. The price with upgraded power supply is well justified if you require the functionality of the INT204 board - <b>Recommended.</b></span></p><p><span style="font-family: arial;">I would like to thank Sound Affairs Pte Ltd for arranging this review. </span></p><p><span style="font-family: arial; font-size: x-small;"><b><br /></b></span></p><p><span style="font-family: arial; font-size: x-small;"><b>Weiss DAC204 D/A Convertor</b></span></p><p><span style="font-family: arial; font-size: x-small;">Price - S$ 3,996 (with stock power supply), $5,000.40 (with Plixir Elite BDC and Statement DC cable)</span></p><p><span style="font-family: arial; font-size: x-small;"><b>Sound Affairs Pte Ltd</b></span></p><p><span style="font-family: arial; font-size: x-small;">110 Lorong 23 Geylang</span></p><p><span style="font-family: arial; font-size: x-small;">#06-03 Victory Centre</span></p><p><span style="font-family: arial; font-size: x-small;">Singapore 388410</span></p><p><span style="font-family: arial; font-size: x-small;"><a href="http://mysoundaffairs.com">http://mysoundaffairs.com</a></span></p><p><span style="font-family: arial; font-size: x-small;"><b><br /></b></span></p><p><span style="font-family: arial; font-size: x-small;"><b><br /></b></span></p><p><br /></p><p><span style="font-family: arial;"><br /></span></p><p><span style="font-family: arial;"> </span></p><p><span style="font-family: arial;"><b><br /></b></span></p>Eric Tehhttp://www.blogger.com/profile/05157135145227727200noreply@blogger.com5tag:blogger.com,1999:blog-684396141123606281.post-53571341210524259692023-05-21T06:04:00.003-07:002023-05-21T20:11:09.111-07:00KZ xHBB PR2 In-Ear Monitor<p><span style="font-family: arial;"><b>Introduction</b></span></p><p><span style="font-family: arial;">Knowledge Zenith (KZ) is back with a planar driver IEM tuned by HBB, the popular Youtuber who runs <i>Bad Guy Good Audio Reviews</i>.

The supplied 1.2m long cable is silver-plated and you can also order a mic version for USD 2 extra. The cable is nothing special - no chin slider, and the 3.5mm plug is not interchangeable. At least it's flexible and doesn't tangle up easily. The PR2 uses 0.75mm pins, so feel free to express yourself with a third-party cable of your choice. I ordered the version with the mic and the voice quality is quite decent and works well enough for conference calls in a quiet environment. </span><p></p><p><span style="font-family: arial;">Included in the box are four tips - one set of foam tips and three pairs of silicon tips in different sizes.

Well, planar drivers are hard to drive, and this one is especially difficult. Driven directly out of a computer or mobile phone headphone jack, the resultant performance is poor to mediocre at best. Apart from limited volume, music sounds strained and confused. </span><span style="font-family: arial;"> </span></p><p><span style="font-family: arial;"><b>Sound Quality</b></span></p><p><span style="font-family: arial;">Bring proper amplification to the party, and the PR2 sounds great. Both an Aurender Flow DAC/headamp and a Questyle M15 dongle DAC had enough power to allow the PR2 to shine. </span></p><p><span style="font-family: arial;">Bass is especially impressive, with a tight and impactful quality. The tuning is neutral, with good and clean vocals and highs. Decay is good, although on the drier side. Staging and imaging are also above average, with good separation and layering. There is a touch of forwardness to the midrange though, which gives vocals a subtle presence boost. You also get speed and details galore, which is especially impressive given the low price tag. </span></p><p><span style="font-family: arial;">Tonally, this is one of the brighter-sounding IEMs on the market, with very little midbass and midrange warmth. You could use EQ to tune this IEM more to your liking, but the intrinsic character won't change that much. If you prefer a warm and bassy IEM, you are better off with something else. </span></p><p><span style="font-family: arial;">In comparison to the Letshuoer S12 Pro (the other planar IEM in my collection), the PR2 is not quite as musical or fun to listen to. The S12 Pro has a much better cable, interchangeable connectors (including a 2.5 and 4.4mm balanced plug), and is easier to drive. The S12 Pro has a warmer and fuller balance, and better dimensionality. The S12 Pro also costs four times more than the PR2, and in my opinion, the performance gap between both is not that big. This gives a clear nod to the PR2 in the value stakes. According to HBB, the PR2 uses the same driver as the KZ PR1 Pro which is almost twice the price of the PR2. In short, you get a lot for your money. </span></p><p><b style="font-family: arial;">Conclusion</b></p><p><span style="font-family: arial;">An outstanding bargain if you are a fan of its neutral tuning. The low sensitivity makes a good dongle DAC or headamp mandatory though - <b>Best Buy.</b></span></p><p><span style="font-family: arial; font-size: x-small;"><b>Price - USD 45</b></span></p><p><span style="font-family: arial; font-size: x-small;"><b><a href="http://kz-audio.com">http://kz-audio.com</a></b></span></p><p><span style="font-family: arial; font-size: x-small;"><b><br /></b></span></p><p><br /></p><p><br /></p>Eric Tehhttp://www.blogger.com/profile/05157135145227727200noreply@blogger.com0tag:blogger.com,1999:blog-684396141123606281.post-63601429136959192992023-03-25T02:42:00.006-07:002023-05-21T20:23:00.656-07:00Canjam Singapore 2023<p><span style="font-family: arial;">Canjam Singapore is now on from <b>March 25-26</b> at Pan Pacific Singapore.

These products were designed by Mr. Masahiro Yamazaki, an experienced engineer who worked for Matsushita Electric Industrial, specialising in circuit design for the Technics Brand which is part of Matsushita. </span></p><p><span style="font-family: arial;">Carefully selected parts such as British LCR styrene capacitors and Amtrans non-magnetic carbon film resistors (AMRG 2W) are used. The hand-made circuit is hard-wired and soldered using lead-free silver solder. </span><span style="font-family: arial;"> </span></p><p><span style="font-family: arial;">A resistor and capacitor circuit is used in conjunction with an electromagnetic wave absorption sheet and metal case of the product to absorb noise. Assuming an output resistance of 220 ohms, Yukimu claims that the RCA Plug attenuates noise at 22 MHz by 18db. </span><span style="font-family: arial;">R-C circuits are commonly used to reduce noise, so this isn't a snake-oil tweak and is well-grounded in science.</span></p><p><span style="font-family: arial;">The RCA Plug utilises a brass shell, while the USB Plug uses a A6061 aluminum case.</span></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi6GA1wJ4OqpScgE9YZKRNL-_ERq4sU15TqFb-P_sFlAe-UFTJzzbw0Jk0E1efXbMAssXoc-KaHSjRCkTJ2aknZzfwIGchr2aKF__sZdt3EzIsMij7WR8hmQx95aFzj7Z3GTNwfdzBLj3EOX5GWA4x6tc5IKJDprZiXQi0H3y04TPF_BJMZagFAYIRm/s1200/20221226_165945.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="675" data-original-width="1200" height="360" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi6GA1wJ4OqpScgE9YZKRNL-_ERq4sU15TqFb-P_sFlAe-UFTJzzbw0Jk0E1efXbMAssXoc-KaHSjRCkTJ2aknZzfwIGchr2aKF__sZdt3EzIsMij7WR8hmQx95aFzj7Z3GTNwfdzBLj3EOX5GWA4x6tc5IKJDprZiXQi0H3y04TPF_BJMZagFAYIRm/w640-h360/20221226_165945.jpg" width="640" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhrCCWcUHTjZZgi5ysj7AGmgqRIe1vmeqSu26PJ10fszUik889IhZeIiRmX1CPTDM5iRSF3NW2p8gsqb5WnIuFEOcryBH1DZJDY9fXiSxS7vQlfZyrIWzmu2wydYa8uiypio60MHfsdTyG9JSEb8A0348CE-u4HlCiJDg4feENDfTO9OgBfHqcVq4Vs/s1200/20221226_170114.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1200" data-original-width="675" height="640" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhrCCWcUHTjZZgi5ysj7AGmgqRIe1vmeqSu26PJ10fszUik889IhZeIiRmX1CPTDM5iRSF3NW2p8gsqb5WnIuFEOcryBH1DZJDY9fXiSxS7vQlfZyrIWzmu2wydYa8uiypio60MHfsdTyG9JSEb8A0348CE-u4HlCiJDg4feENDfTO9OgBfHqcVq4Vs/w360-h640/20221226_170114.jpg" width="360" /></a></div><br /><p></p><p><span style="font-family: arial;"><b>Description</b></span></p><p><span style="font-family: arial;">Both products come in a beautiful wood box, with a certificate confirming that the product was manufactured and evaluated by the named employee which just so happened to be Masahiro-san. </span></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhg6rTYFXoAizlF6I4hc0-pW1S_K7uIYVM1psr5OITUTzDMaPfH69Lgg0H7JqV6Y6W67F1xmal9p5VV3ApxhkB4OZW-ub7_mtGad8WnOxA46wai7eerG_LLmld5aG-HJvp9GpzvvqOVIbt0LQFAf19XeGRlN7waqEl6iouCip3oGm0Q8mlClGUh4x6E/s1200/20221226_170408.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="675" data-original-width="1200" height="360" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhg6rTYFXoAizlF6I4hc0-pW1S_K7uIYVM1psr5OITUTzDMaPfH69Lgg0H7JqV6Y6W67F1xmal9p5VV3ApxhkB4OZW-ub7_mtGad8WnOxA46wai7eerG_LLmld5aG-HJvp9GpzvvqOVIbt0LQFAf19XeGRlN7waqEl6iouCip3oGm0Q8mlClGUh4x6E/w640-h360/20221226_170408.jpg" width="640" /></a></div><br /><span style="font-family: arial;"><br /></span><p></p><p><span style="font-family: arial;">Yukimu's website explains that the RCA Plug can be used on any RCA analog or digital socket (including output sockets).</span></p><p><span style="font-family: arial;"><b>In Use</b></span></p><p><span style="font-family: arial;">Like any grounding product, some experimentation is required to get the most out of the Yukimu. On a Schitt Freya+ preamp, the effect of the RCA Plug </span><span style="font-family: arial;">on each socket varied in intensity. The intensity was highest on a spare input, while the output socket was slightly tamer.</span></p><p><span style="font-family: arial;">Regardless of location, the effect was quite consistent. You get a tightening of the bass, and clearer and more extended high frequencies. While the midrange clarity and texture improved, there is an increase in "presence" that moves vocals forward in the soundstage. While expressiveness of singers improved, sibilance was also more noticeable. </span></p><p><span style="font-family: arial;">The preferred intensity will be a matter of taste. I found that the tonality of my system was too forward and bright when used on the input socket, and just right on the output socket. </span></p><p><span style="font-family: arial;">The effect of the USB Plug is similar, but I found that the increase in dynamics and bass heft to be more pronounced than the RCA Plug, making the USB Plug sound more balanced. Deployed on the front USB port of my Intel-NUC Roon ROCK server, there was an all-round increase in dynamics, clarity and focus. There was less alteration to the tone of my system and if I had to choose just one, my money would be on the USB Plug. </span></p><p><span style="font-family: arial;">The audiophile mind already predicted that using both products at the same time would result in an overly bright and forward presentation. Somehow, both products sounded quite good together, although the tone was still on the bright side of neutral. Who would have guessed?</span></p><p><span style="font-family: arial;"><b>Conclusion</b></span></p><p><span style="font-family: arial;">This is an effective product that is meticulously made. The price tag is reasonable for the performance although some caution should be noted given the resultant shift in tonal balance. Judicious trial and error is required also to get best results - <b>Highly Recommended.</b></span></p><p><span style="font-family: arial;">Yukimu products are available in Singapore from Audio Basic.</span></p><div style="text-align: left;"><span style="font-family: arial; font-size: x-small;"><b>Yukimu PNA-RCA01 / </b></span><b style="font-family: arial; font-size: small;">PNA-USB01</b><b style="font-family: arial; font-size: small;"> - S$ 520 each (promotional price)</b></div><div style="text-align: left;"><br /></div><div style="text-align: left;"><span style="font-family: arial; font-size: x-small;"><b>Audio Basic<br /></b></span><span style="font-family: arial; font-size: x-small;">1 Coleman Street<br /></span><span style="font-family: arial; font-size: x-small;">#02-12, The Adelphi <br /></span><span style="font-family: arial; font-size: x-small;">Singapore 179803<br /></span><span style="font-family: arial; font-size: x-small;">http://audiobasic.blogspot.com</span><span style="font-family: arial; font-size: x-small;"><br /></span></div><p style="text-align: left;"><span style="font-family: arial;"><b><br /></b></span></p><p><br /></p><p><br /></p><p><span style="font-family: arial;"> </span></p><p><br /></p>Eric Tehhttp://www.blogger.com/profile/05157135145227727200noreply@blogger.com0tag:blogger.com,1999:blog-684396141123606281.post-39263261231821973932022-12-04T06:46:00.011-08:002023-11-27T21:49:30.200-08:00International Sound & Sight Exhibition 2022<p><span style="font-family: arial;">International Sound & Sight Exhibition (ISSE) ran from the 2nd to 4th of December 2022 at Holiday Inn Singapore Orchard City Centre.

EAhibrid was showcasing their Pure DC B1 battery supply that uses 2170 lithium batteries that are also used in Tesla EVs. Mr. Paul Huang, founder of EAhibrid explained some of the technology used in the Pure DC B1. I happen to have one at home, so I will do a detailed review on that soon.</p><p>Cornerstone Audio is new to ISSE. For such a young company, they have an impressive list of brands under their belt, including Quadraspire (racks), QLN speakers, Sean Jacob power supplies and Lab 12. </p><p>The very cute looking accessory is both a resonator and grounding device.

Offering a choice of both 6922 and 6SN7 tubes which are switchable on-the-fly, the Analog Bridge also uses a 5AR4 tube rectified power supply. This is the perfect candidate for adding tube warmth into a system.

The device is a barrel-shaped plug with various connectors available :- RCA, 3.5mm mini plug, banana and spades. The barrel contains 100 cm2 of high-purity aluminum foil treated with a special etching process to create cavities that increase the surface area to 11,000 cm2.

The plates comprise a combination of stainless steel, brass and copper plates. The plates are stacked, with a 0.5mm air gap between each plate. The box measures 80mm (W) x 35mm (H) and 111mm (D) and weighs 775 grams.</span></p><p></p><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhdbJO95wcwy7mbmK195b8O4KwsJKArKQ1R76d1iY2OxU3I8JodTsX889p16u_vnua2thZi-UbsR3ftZZkUhLe2XbdAlHnESOC0J7Tf_DESLM1WGmc1Z91ZrESicDPgSpQm9tfYjND5vXgkqa5bHsrnYZoavMPShp-Gj7eQycxnRSdYF6mWjv2rYMms/s500/crystale_2.jpg" style="margin-left: auto; margin-right: auto;"><img border="0" data-original-height="400" data-original-width="500" height="512" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhdbJO95wcwy7mbmK195b8O4KwsJKArKQ1R76d1iY2OxU3I8JodTsX889p16u_vnua2thZi-UbsR3ftZZkUhLe2XbdAlHnESOC0J7Tf_DESLM1WGmc1Z91ZrESicDPgSpQm9tfYjND5vXgkqa5bHsrnYZoavMPShp-Gj7eQycxnRSdYF6mWjv2rYMms/w640-h512/crystale_2.jpg" width="640" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;"><span style="font-family: arial; font-size: x-small;">Picture taken from Kojo's website</span></td></tr></tbody></table><span style="font-family: arial;"><br /></span><p></p><p><span style="font-family: arial;">There are two screw terminals at each end of the box.

The first piece is the termination plug and is interchangeable. The second piece is the main housing, and the last piece is the screw terminal that accepts the spade-terminated grounding wire that connects to the E Ground Box. This allows you to easily change the termination plug in case your needs change in the future, and also to stack the plugs if required. How you apply this product in your system is limited only by your imagination.</span></p><p><span style="font-family: arial;"><b>Sound Quality</b></span></p><p><span style="font-family: arial;">Kojo is not my foray into grounding products, being a long-time user of Entreq ground boxes. Grounding accessories take a bit of experimentation to get right, with the results being very much system and component-dependent. Kojo products come in at a lower price-point compared to Entreq and are more compact, allowing you to deploy them in tight spaces.</span></p><p><span style="font-family: arial;">The Crystal EP Plug increased focus and vocal texture, with more bass power. Dynamic contrast increased with instruments and vocals becoming more distinct. The effect was very noticeable with a 3.5mm EP Plug inserted into a Creative Soundblaster X4 DAC/headamp, with similar results pairing an RCA EP Plug with a Schitt Audio Freya+ preamp. Using twin RCA EP Plugs (on an unused input and output socket) increased the effect, but also sounded a bit too forceful and artificial for my taste. </span></p><p><span style="font-family: arial;">Linking the EP Plug to a Crystal E Ground Box increased the level of refinement across the board, and added a calm sereneness to the music. It also added midbass weight which balanced out the extra energy on the midrange and treble. This turned out to be my favourite combination in listening tests. </span></p><p><span style="font-family: arial;">As counter-intuitive as it sounds, do also try grounding the phono stage in your integrated amplifier (even if you don't play records). Attaching the Crystal E Ground Box to the ground lug of the Marantz 40N gave great sonic dividends, sorting out a vague and diffuse sound stage. </span></p><p><span style="font-family: arial;">I tried adding Crystal EP Plugs to the negative terminal of my speakers. While the effect was similar, I found it to be more subtle compared to tweaking the source equipment. As I only had a single Crystal E Ground Box on hand, I was not able to ground both plugs.</span></p><p><span style="font-family: arial;"><b>Conclusion</b></span></p><p><span style="font-family: arial;">The Kojo Crystal EP Plug and Crystal E Ground Box earn an easy <b>Best Buy</b> award from me. Improve your system for a modest outlay! However, as with all grounding products, do try before you buy since tweaks of this nature are highly system-dependent. </span></p><p><span style="font-family: arial;">A big thank you goes out to Sky Audio Singapore, local distributor of Kojo products for providing the review samples. I personally purchased the EP Plug and Crystal E Ground Box.</span></p><p><span style="font-family: arial;">Catch them too at International Sound & Sight Exhibition 2022.

was founded in 2004 and is based in Eindhoven, The Netherlands. Helmed by Eelco
Grimm and Guido Tent, Grimm is well-known in professional audio circles. <o:p></o:p></span></span></p><p class="MsoNormal"><span lang="EN-US"><span style="font-family: arial;">Grimm

the hood, the MU1 runs its software on a Linux-based Intel i3 computer board and an in-house designed FPGA board which runs format and sample rate
conversion. An ultra-low jitter clock (<0.6 ps RMS (>10 Hz)) completes
the picture. Hey, it’s a Grimm and you wouldn’t expect anything less would you?<o:p></o:p></span></span></p><p class="MsoNormal"><span lang="EN-US"><span style="font-family: arial;">At the
moment, the MU1 is a Roon-based solution that acts as both Roon Core and Roon
End-Point. There are plans to offer a DLNA solution in the future though. Tidal and Qobuz support are available through the Roon app, but Spotify Connect is not supported. <o:p></o:p></span></span></p><p class="MsoNormal"><span lang="EN-US"><span style="font-family: arial;">The MU1 is
available with internal music storage of up to 8TB. Otherwise, you can use network
storage or an external drive connected to the twin USB 3.0 ports on the MU1. <o:p></o:p></span></span></p><p class="MsoNormal"><span lang="EN-US"><span style="font-family: arial;">Three
digital inputs (AES, coaxial and Toslink) are provided which allows the MU1 to process external data streams, allowing other digital sources to enjoy the
goodness of the MU1.<o:p></o:p></span></span></p><p class="MsoNormal"><span lang="EN-US"><span style="font-family: arial;">The FPGA upsamples
the data stream to either 2x or 4x of the sampling rate before being sent to
the two AES or single coaxial digital outputs. A fourth digital output via an
RJ45 port serves as a proprietary connection for the Grimm LS1 speaker. The
digital outputs may also be configured for 6-channel output for surround sound
use. No preamplifier ? No issue – there is a digital volume control on hand too.
As there is no way to attenuate DSD streams, conversion to PCM is required to
make use of the volume control. <o:p></o:p></span></span></p><p class="MsoNormal"><span style="font-family: arial;"><b><span lang="EN-US">Setting
Up</span></b><span lang="EN-US"><o:p></o:p></span></span></p><p class="MsoNormal"><span lang="EN-US"><span style="font-family: arial;">Hook up the
MU1 to your network via its LAN port (wireless connection is not available),
switch on the power, and you are ready to go. The difficulty factor depends on
how familiar you are with Roon. As a long-time Roon user, setup was
straightforward. The well-written manual is comprehensive, and I spent less
than an hour setting up the MU1 and loading my test tracks into the internal
drive. The unit connected to the internet and prompted an upgrade to its firmware. Grimm has worked hard in the past to upgrade the performance of the MU1, so you can expect steady improvements in performance over time.<o:p></o:p></span></span></p><p class="MsoNormal"><span style="font-family: arial;"><b><span lang="EN-US">Operation</span></b><span lang="EN-US"><o:p></o:p></span></span></p><p class="MsoNormal"><span lang="EN-US"></span></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjfEAZe1V1tg6SaL8CevbF8-u3AsSSQFhKTpw8qQSxP1Tqbt0G--twI7C3Q2NnHxmJDvqFLFfv881jlmwb_C0cPIivAuo-ezTDtcSt-eNPKZGSyRuQX_tCbccqk0Ihuav1huxx7aqtLO48SAPl48hno5FzEHiinCZbUVTpHMQPzo6Nj4bzaZ4rIldPU/s1200/mu1%20top.jpg" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" data-original-height="675" data-original-width="1200" height="360" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjfEAZe1V1tg6SaL8CevbF8-u3AsSSQFhKTpw8qQSxP1Tqbt0G--twI7C3Q2NnHxmJDvqFLFfv881jlmwb_C0cPIivAuo-ezTDtcSt-eNPKZGSyRuQX_tCbccqk0Ihuav1huxx7aqtLO48SAPl48hno5FzEHiinCZbUVTpHMQPzo6Nj4bzaZ4rIldPU/w640-h360/mu1%20top.jpg" width="640" /></a></div><br /><p></p><p class="MsoNormal"><span style="font-family: arial;"><br /></span></p><p class="MsoNormal"><span style="font-family: arial;"><br /></span></p><p class="MsoNormal"><span style="font-family: arial;"><br /></span></p><p class="MsoNormal"><span style="font-family: arial;"><br /></span></p><p class="MsoNormal"><span style="font-family: arial;"><br /></span></p><p class="MsoNormal"><span style="font-family: arial;"><br /></span></p><p class="MsoNormal"><span style="font-family: arial;"><br /></span></p><p class="MsoNormal"><span style="font-family: arial;"><br /></span></p><p class="MsoNormal"><span style="font-family: arial;"><br /></span></p><p class="MsoNormal"><br /></p><p class="MsoNormal"><span style="font-family: arial;"><br /></span></p><p class="MsoNormal"><span style="font-family: arial;">The giant

sampling rate conversion can be switched to “Original”, “2FS Oversampling” or “4FS
Oversampling”. If “2FS Oversampling” is selected, files at 44.1 and 48 kHz sampling
rate will be upsampled at 2FS, while 88.2 and 96 kHz sampling rate files will
be played at their native sampling rate. In the case of files over the targeted
oversampling rate, they will be downsampled (e.g. 8FS and DSD material). The MU1
also supports DoP in case the user prefers to play DSD files natively on their
DAC.</span></p><p class="MsoNormal"><span lang="EN-US"><span style="font-family: arial;">The USB port can also be enabled to output data, but I found it sounded inferior to the AES and SPDIF outputs when paired with my Totaldac D1-Six DAC.</span></span><span style="font-family: arial;"> </span></p><p class="MsoNormal"><span lang="EN-US"><span style="font-family: arial;">Programmable
remote-control operation is possible if an external IR receiver is connected to
the 3.5mm jack provided on the rear of the unit. As I did not have an IR
receiver on hand, this function was not tested.<o:p></o:p></span></span></p><p class="MsoNormal"><span style="font-family: arial;"><b><span lang="EN-US">Sound
Quality</span></b><span lang="EN-US"><o:p></o:p></span></span></p><p class="MsoNormal"><span lang="EN-US"><span style="font-family: arial;">The MU1 is simply
the finest quality Roon playback I have heard bar none. The tone is a fluid,
almost analog-like quality with powerful dynamics and extended highs. My Roon ROCK (Roon Optimized Core Kit) server runs on an Intel i7-based NUC fitted into a fan-less Akasa Turing
chassis for fully passive cooling. The MU1 ran rings around my home rig, to the
point that the performance gap between the two was simply unbridgeable. <o:p></o:p></span></span></p><p class="MsoNormal"><span lang="EN-US"><span style="font-family: arial;">One very
important caveat is that the performance lead of the MU1 depends on your source
material and how you employ upsampling (or not). The lead narrows considerably
if you are playing DSD natively, or PCM
files without upsampling. <o:p></o:p></span></span><span style="font-family: arial;">I am personally not a big fan of upsampling, but the MU1 does this in a way that improves sound quality so significantly in terms of separation and detail that you will just leave the upsampling enabled permanently. </span></p><p class="MsoNormal"><span lang="EN-US"><span style="font-family: arial;">If you are
a DSD fan and your DAC does not support DoP, operation will also be cumbersome.
You will need to change your Roon settings to output the digital stream via the
USB port, which then leaves you without upsampling. You could connect up your
DAC via the SPDIF or AES output, and toggle between the two signal paths, but
the routine will quickly become old. The other alternative would be to stick to
the SPDIF or AES output, and convert all DSD streams to PCM – something bound
to offend a DSD purist!</span></span></p><p class="MsoNormal"><span lang="EN-US"><span style="font-family: arial;">Coming back to the sonics, there is a certain rightness to the M</span></span><span style="font-family: arial;">U1. Bass is very tight and powerful, and piano notes have a rich solidity and realism that fills the room. The midrange is on the warmer side of things, and vocals have a warmth and richness that is creamy and inviting. This is coupled with very extended and clear high frequencies that reveals plenty of detail and air. Counter-balanced with the hefty low-end and warm midrange, you end up with a tone that is not bright at all, yet highly detailed and easy to listen to. </span><span style="font-family: arial;">This is not a product that plays the neutrality card, but instead takes the path of connecting emotionally with the listener. </span></p><p class="MsoNormal"><span lang="EN-US"><span style="font-family: arial;">The way the MU1 produces music is very special - music is highly energetic, yet natural and non-fatiguing. Your brain instantly registers that the MU1 is a rare and outstanding product that stands out from the crowd. </span></span></p><p class="MsoNormal"><span lang="EN-US"><span style="font-family: arial;"><b>Closing Thoughts</b></span></span></p><p class="MsoNormal"><span style="font-family: arial;">This is a niche product. If you dislike Roon or want ruler-flat neutrality, you should look at something else. Some audiophiles would balk at the price-tag of the MU1 and insist that this is an overpriced computer server build. An audition should quickly sort that out. I know of several experienced audiophiles and reviewers that purchased the MU1 after experiencing what it brings to their system. Although the outcome would be Grimm for my bank account, I definitely want one! <b>Highly Recommended.</b></span></p><p class="MsoNormal"><span style="font-family: arial;"><b><br /></b></span></p><p class="MsoNormal"><span style="font-family: arial;"><b>Grimm MU1 Music Player</b></span></p><p class="MsoNormal"><span style="font-family: arial;">Price - S$16,000 (excluding GST and with 4TB SSD internal storage)</span></p><p class="MsoNormal"><span style="font-family: arial;">Grimm products are available from :-</span></p><div><br /></div><span style="font-family: arial;"><a href="https://periodic-table-of-elements.net/" style="-webkit-tap-highlight-color: transparent; border: 0px; box-sizing: border-box; font-size: inherit; font-stretch: inherit; font-style: inherit; font-variant: inherit; line-height: inherit; margin: 0px; padding: 0px; text-decoration-line: none; vertical-align: baseline;"><span style="-webkit-tap-highlight-color: transparent; border: 0px; box-sizing: border-box; font-size: inherit; font-stretch: inherit; font-style: inherit; font-variant: inherit; line-height: inherit; margin: 0px; padding: 0px; vertical-align: baseline;"><b>Sound Affairs Pte Ltd</b></span><div class="rte" style="-webkit-tap-highlight-color: transparent; border: 0px; box-sizing: border-box; color: #2a2a2a; font-size: 0.9375rem; font-stretch: inherit; font-style: inherit; font-variant: inherit; font-weight: inherit; line-height: 1.55; margin: 0px; padding: 0px; vertical-align: baseline;"><p style="-webkit-tap-highlight-color: transparent; border: 0px; box-sizing: border-box; font-size: 0.9375rem; font-stretch: inherit; font-style: inherit; font-variant: inherit; line-height: 1.55; margin: 0px; padding: 0px; vertical-align: baseline;">110 Lorong 23 Geylang #06-03<br style="-webkit-tap-highlight-color: transparent; box-sizing: border-box; margin: 0px; padding: 0px;" />Victory Centre<br style="-webkit-tap-highlight-color: transparent; box-sizing: border-box; margin: 0px; padding: 0px;" />Singapore 388410<br style="-webkit-tap-highlight-color: transparent; box-sizing: border-box; margin: 0px; padding: 0px;" /></p></div></a><span style="color: #2a2a2a;"><span style="font-size: 15px;"><a href="http://www.mysoundaffairs.com/">http://www.mysoundaffairs.com/</a></span></span></span><div><span style="color: #2a2a2a; font-family: arial;"><span style="font-size: 15px;"><br /></span></span><div><span style="font-family: arial;"><span style="color: #2a2a2a;"><span style="font-size: 15px;"><br /></span></span></span></div><div><br /></div></div>Eric Tehhttp://www.blogger.com/profile/05157135145227727200noreply@blogger.com0tag:blogger.com,1999:blog-684396141123606281.post-42660722284369755862022-02-05T02:57:00.002-08:002022-02-06T00:59:05.781-08:00WFH Special #2 - Creative Outlier Air V3<p><span style="font-family: arial;"><b>Introduction</b></span></p><p><span style="font-family: arial;">Not a fan of wired headsets for your office conference calls? Consider true wireless in-ear-monitors as an alternative. Lightweight and comfortable, they are a more practical choice in tropical weather if you do not run air-conditioning. </span></p><p><span style="font-family: arial;">Apart from office use, they will be perfect for accompanying you for your exercise sessions, or travelling. This makes them an easy sell to the Minister of Finance at home. </span></p><p><span style="font-family: arial;"><b>Description</b></span></p><p><span style="font-family: arial;">The Outlier Air V3 ("V3") is the third-generation version of the Outlier Air - Creative's true wireless in-ear-monitors. </span></p><p><span style="font-family: arial;">The charging case remains at about the same size as the original Outlier Air ("V1") which means that it is bulky and clunky to carry around. Sharing the same footprint, the V3 case is slightly taller. You do get 40 hours of playtime though with 10 hours per charge, which is improvement over the 30 hour lifespan of the original model. The case may be charged via a USB-C port, or Qi-compatible wireless charging. Charging time via cable is between 2 to 3 hours.</span></p><p><span style="font-family: arial;"><br /></span></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEgZw3KKxsZe4AKE_IN73PNgXpW0sbVRNDgTOzE_Wo6wdWUkDewByNsftpfhkl7UlpubcA03FMN3keh5m9exTzHrq2FIgGPB5NzNas9M5tzUYTp5oygEPZznIX8aJrOHj_Z2SGUw42jmxpji93t32P_QKD4axud15LAT9N5qtERa3dTV_X3gzRFGzUkh=s4032" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="4032" data-original-width="2268" height="640" src="https://blogger.googleusercontent.com/img/a/AVvXsEgZw3KKxsZe4AKE_IN73PNgXpW0sbVRNDgTOzE_Wo6wdWUkDewByNsftpfhkl7UlpubcA03FMN3keh5m9exTzHrq2FIgGPB5NzNas9M5tzUYTp5oygEPZznIX8aJrOHj_Z2SGUw42jmxpji93t32P_QKD4axud15LAT9N5qtERa3dTV_X3gzRFGzUkh=w360-h640" width="360" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEjH22qUhiEmYO3mLzcpjETuc8Ppaa3AM-HEEGaLS_XJsLGhRx7PsH6CFz2xx_GEY0xVzvLJIUEouO-ItcWJq8lskK9tPtwYNL8fOPu-0w_X01LwOKSCcKC82wfoDS_AksfK-GreJM8NnSMbMgOYOuJsp0KdqHOkqKu9yjKIdioJ08UzHbqmhkOhfGzN=s4032" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="4032" data-original-width="2268" height="640" src="https://blogger.googleusercontent.com/img/a/AVvXsEjH22qUhiEmYO3mLzcpjETuc8Ppaa3AM-HEEGaLS_XJsLGhRx7PsH6CFz2xx_GEY0xVzvLJIUEouO-ItcWJq8lskK9tPtwYNL8fOPu-0w_X01LwOKSCcKC82wfoDS_AksfK-GreJM8NnSMbMgOYOuJsp0KdqHOkqKu9yjKIdioJ08UzHbqmhkOhfGzN=w360-h640" width="360" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEigVS725aL7_-Epi0yWO77hHtEYO8nmsbWUq7PrOphRrJUxbWzLfYM-oIjTf4EIpPJERP4Cf7ap2IAKUUxxcYx4yV-16eTCJk2Ad7VjYlJJTeJsEHB-WUQahGxWpos9_2AGbEUGBF4bdp_Ms20HkwncvCIh4U9-dZi0EbW3Lf60joUV5B7fbJBfsWG4=s4032" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="2268" data-original-width="4032" height="360" src="https://blogger.googleusercontent.com/img/a/AVvXsEigVS725aL7_-Epi0yWO77hHtEYO8nmsbWUq7PrOphRrJUxbWzLfYM-oIjTf4EIpPJERP4Cf7ap2IAKUUxxcYx4yV-16eTCJk2Ad7VjYlJJTeJsEHB-WUQahGxWpos9_2AGbEUGBF4bdp_Ms20HkwncvCIh4U9-dZi0EbW3Lf60joUV5B7fbJBfsWG4=w640-h360" width="640" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><br /></div><br /><span style="font-family: arial;"><br /></span><p></p><p><span style="font-family: arial;">The V3 uses Bluetooth V 5.2. Supported audio codes are AAC and SBC. Purists will be disappointed to note that aptX support has been dropped. Like the V1, the V3 is IPX5 certified for water resistance. </span></p><p><span style="font-family: arial;">The driver for the V3 uses a 6 mm bio-cellulose driver, which is a change from the 5.6 mm graphene-coated drivers used in the V1. </span></p><p><span style="font-family: arial;">The V3 case, fully loaded with earbuds weighed in at 76.6 grams, compared to 61.8 grams for the V1. The earbuds for the V3 are 5.3 grams in weight (per side), while the V1 are 5.1 grams. </span></p><p><span style="font-family: arial;">By default, the usual volume and play control functions, Siri or Google Assistant, as well as ambient and active noise reduction modes are accessible via touch control. However, you can also customise the controls via the Creative App. This App is also used to flash firmware upgrades and applying EQ settings.</span></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEjFk-hp7okmdpmEzeZtEat85aqU7dwU4QXpyBdZxRNHuLjd19CwoLDOtbpQuh-vB_BoRbLd75aGYR3JABlRBwvA8mZRdw1byrkfbks88SA9YAdOxZ-rMgbGWzubdH3MxZUGHIN20kn0HJdf4Hb8aIfXVL112WjbPhgaYVspYqg1YRDBRnoxkVhreKLD=s3040" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3040" data-original-width="1440" height="640" src="https://blogger.googleusercontent.com/img/a/AVvXsEjFk-hp7okmdpmEzeZtEat85aqU7dwU4QXpyBdZxRNHuLjd19CwoLDOtbpQuh-vB_BoRbLd75aGYR3JABlRBwvA8mZRdw1byrkfbks88SA9YAdOxZ-rMgbGWzubdH3MxZUGHIN20kn0HJdf4Hb8aIfXVL112WjbPhgaYVspYqg1YRDBRnoxkVhreKLD=w304-h640" width="304" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEjc0yOzbfOmXM-tCywUHsStoi4kmfAGIVKMVzIZUDyfHu5g7Q9zqkITlVvFHWN0ma7ozl0X1HC_d4dU_KkslBAJlpsa2BgWR0NpVw2FsCkGHKUFSl-a5jPjbXCchauM5ZfQIfTjPoFY1Vl-rOtzQPFp3CXh_85oRtOS-o9P8MTogSbNJmijb0qQOlDm=s3040" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3040" data-original-width="1440" height="640" src="https://blogger.googleusercontent.com/img/a/AVvXsEjc0yOzbfOmXM-tCywUHsStoi4kmfAGIVKMVzIZUDyfHu5g7Q9zqkITlVvFHWN0ma7ozl0X1HC_d4dU_KkslBAJlpsa2BgWR0NpVw2FsCkGHKUFSl-a5jPjbXCchauM5ZfQIfTjPoFY1Vl-rOtzQPFp3CXh_85oRtOS-o9P8MTogSbNJmijb0qQOlDm=w304-h640" width="304" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEjUVlZ-9IIYS71h8qwV7SVXn_1PazwXbNT2fQE-9xDUOWs7AzVXdXHz4NBct8f1QKoA2sPOHcXTQS9sO3ipO8cfKzjKwQEd3Ko_V_1dSUwsAbyGi2RRQtusAQGTDibY_zqmyr_O_FnfatIesq__AqeGnzxtfUN2Yf9bDm_M3vEbJ64A6UV6j5y1PqyU=s3040" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3040" data-original-width="1440" height="640" src="https://blogger.googleusercontent.com/img/a/AVvXsEjUVlZ-9IIYS71h8qwV7SVXn_1PazwXbNT2fQE-9xDUOWs7AzVXdXHz4NBct8f1QKoA2sPOHcXTQS9sO3ipO8cfKzjKwQEd3Ko_V_1dSUwsAbyGi2RRQtusAQGTDibY_zqmyr_O_FnfatIesq__AqeGnzxtfUN2Yf9bDm_M3vEbJ64A6UV6j5y1PqyU=w304-h640" width="304" /></a></div><br /><p></p><p><span style="font-family: arial;">Besides the Creative App, you will need to download the SXFI App to transfer your personal profile over to the Outlier Air. Music also has to be played through this App in order to enjoy SXFI. This is an inconvenience, especially if your music source is from a streaming service since the App supports playback of local music files only. </span></p><p><span style="font-family: arial;"><b>Use, Fit and Comfort </b></span></p><p><span style="font-family: arial;">Taking the earbuds out of the case will put the V3 into pairing mode automatically. You also have the option of just using one side (useful for conference calls). I noticed that the earbuds would also squeal loudly when being returned to their case. I traced this to feedback from the microphones when either ambient mode or active noise reduction is being used. Alternatively, place the earbuds back in the case one at a time to avoid this. </span></p><p><span style="font-family: arial;">Fit will be subjective. The V1 with its larger shell, fitted my ears better and provided a better seal. The V3 felt less secure, and did not seal as well in my right ear. However, this can be easily remedied by changing out the tips to suit your personal preference. The V3 sat quite securely during exercise sessions, although I would feel less confident to use them for long runs. They were also comfortable enough to be used for long listening sessions.</span></p><p><span style="font-family: arial;">Battery life was consistent with specifications and the V3 had no issue connecting with my phone placed about 6m away so long as line-of-sight is maintained. </span></p><p><span style="font-family: arial;"><b>Sound</b></span></p><p><span style="font-family: arial;">The V3 turned in a competent performance, with a significant improvement over the V1. Bass performance was tighter and more impactful, while midrange was much clearer - the V1 had a tendency to sound muffled and nasal. High frequencies also had a touch more openness and extension. </span><span style="font-family: arial;">Soundstaging on the V3 was also wider and more spacious, with better placement of voices and instruments.</span><span style="font-family: arial;"> </span></p><p><span style="font-family: arial;">Tonally, I would say that the V3 had a slightly warm balance, with neutral bass and highs, and a laidback midrange. Some listeners may find the bass balance a bit light, but this can be fixed in the EQ settings.</span></p><p><span style="font-family: arial;">Putting aside the richer feature set, the V3's sonic performance is reason enough to upgrade from the V1. </span></p><p><span style="font-family: arial;">The active noise reduction works reasonably well. However, as the name suggests it attenuates outside noise instead of canceling it. Nevertheless, the end result is good enough for the typical home environment, or for traveling. </span></p><p><span style="font-family: arial;">The microphone pickup is above average and voice pick-up is reasonably clear. </span></p><p><span style="font-family: arial;"><b>Conclusion</b></span></p><p><span style="font-family: arial;">The V3 is a solid performer at a bargain price. The Singapore online shop regularly runs promotions, and you can usually get a pair at a good discount - <b>Best Buy</b></span></p><p><span style="font-family: arial; font-size: x-small;"><b>Creative Outlier Air V3</b></span></p><div class="row" style="background-color: white; box-sizing: border-box; color: #666666; display: flex; flex-wrap: wrap; font-family: proxima-nova, sans-serif; margin-left: -15px; margin-right: -15px;"><div class="col-sm-4 specs-col" style="box-sizing: border-box; float: left; min-height: 1px; padding-left: 15px; padding-right: 60px; position: relative; width: 390px;"><dl class="spec-item" style="box-sizing: border-box; margin-top: 0px;"><dt style="box-sizing: border-box;"><h5 class="spec-subheader" style="box-sizing: border-box; color: black; font-weight: normal; margin-bottom: 5px; margin-top: 0px;"><span style="font-size: x-small;">Driver</span></h5></dt></dl><dl class="spec-item" style="box-sizing: border-box; margin-top: 0px;"><dt style="box-sizing: border-box;"><h5 class="spec-subheader" style="box-sizing: border-box; color: black; font-weight: normal; margin-bottom: 5px; margin-top: 0px;"><span style="font-size: x-small;">6 mm Bio-cellulose Driver</span></h5></dt></dl></div><div class="col-sm-4 specs-col" style="box-sizing: border-box; float: left; min-height: 1px; padding-left: 15px; padding-right: 60px; position: relative; width: 390px;"><dl class="spec-item" style="box-sizing: border-box; margin-top: 0px;"><dt style="box-sizing: border-box;"><h5 class="spec-subheader" style="box-sizing: border-box; color: black; font-weight: normal; margin-bottom: 5px; margin-top: 0px;"><span style="font-size: x-small;">Battery Type and Life</span></h5></dt><dd class="description" style="box-sizing: border-box; margin-left: 0px; padding-left: 0px;"><span style="font-size: x-small;">Battery in Charging Case: 1 x Rechargeable Lithium Polymer Battery 450 mAh, Battery in Earbuds: 2 x Rechargeable Lithium-ion Polymer Battery 55 mAh</span></dd></dl><dl class="spec-item" style="box-sizing: border-box; margin-top: 0px;"><dt style="box-sizing: border-box;"><h5 class="spec-subheader" style="box-sizing: border-box; color: black; font-weight: normal; margin-bottom: 5px; margin-top: 0px;"><span style="font-size: x-small;">Charging Time</span></h5></dt><dd class="description" style="box-sizing: border-box; margin-left: 0px; padding-left: 0px;"><span style="font-size: x-small;">2 to 3 hours</span></dd></dl><dl class="spec-item" style="box-sizing: border-box; margin-top: 0px;"><dt style="box-sizing: border-box;"><h5 class="spec-subheader" style="box-sizing: border-box; color: black; font-weight: normal; margin-bottom: 5px; margin-top: 0px;"><span style="font-size: x-small;">Connector Type</span></h5></dt><dd class="description" style="box-sizing: border-box; margin-left: 0px; padding-left: 0px;"><span style="font-size: x-small;"><em style="box-sizing: border-box;">Bluetooth</em> 5.2</span></dd></dl><dl class="spec-item" style="box-sizing: border-box; margin-top: 0px;"><dt style="box-sizing: border-box;"><h5 class="spec-subheader" style="box-sizing: border-box; color: black; font-weight: normal; margin-bottom: 5px; margin-top: 0px;"><span style="font-size: x-small;">Audio Codec</span></h5></dt></dl><dl class="spec-item" style="box-sizing: border-box; margin-top: 0px;"><dd class="description" style="box-sizing: border-box; margin-left: 0px; padding-left: 0px;"><span style="font-size: x-small;">AAC, SBC</span></dd></dl></div><div class="col-sm-4 specs-col" style="box-sizing: border-box; float: left; min-height: 1px; padding-left: 15px; padding-right: 60px; position: relative; width: 390px;"><dl class="spec-item" style="box-sizing: border-box; margin-top: 0px;"><dt style="box-sizing: border-box;"><h5 class="spec-subheader" style="box-sizing: border-box; color: black; font-weight: normal; margin-bottom: 5px; margin-top: 0px;"><span style="font-size: x-small;">Weather-proof Resistant</span></h5></dt><dd class="description" style="box-sizing: border-box; margin-left: 0px; padding-left: 0px;"><span style="font-size: x-small;">IPX5</span></dd></dl><dl class="spec-item" style="box-sizing: border-box; margin-top: 0px;"><dt style="box-sizing: border-box;"><h5 class="spec-subheader" style="box-sizing: border-box; color: black; font-weight: normal; margin-bottom: 5px; margin-top: 0px;"><span style="font-size: x-small;">Price - S$ 99</span></h5></dt></dl></div></div>Eric Tehhttp://www.blogger.com/profile/05157135145227727200noreply@blogger.com0tag:blogger.com,1999:blog-684396141123606281.post-30221283624131738362022-01-23T02:47:00.001-08:002022-01-23T02:48:08.947-08:00Nelson Pass B1 with Korg Triode Preamp Kit<p><span style="font-family: arial;"><b>Introduction</b></span></p><p><span style="font-family: arial;">The B1 with Korg Triode was introduced by Nelson Pass in 2017 at the Burning Amp Festival. The B1 is an established design which is as about as easy as it gets - a buffered passive preamp. </span></p><p><span style="font-family: arial;">The Nutube from Korg is a vacuum fluorescent display that operates similarly to a triode vacuum tube. The green glow reminds me of the old computer monitor that came with my cousin's Apple II computer ages ago. This also gives this kit a cool factor that only audiophiles are able to appreciate. The rest of the world probably just thinks that we are dorks! </span></p><p><span style="font-family: arial;">Why not just use a vacuum tube? Vacuum tubes use considerably more power and have short operating lives. The typical vacuum triode would have a lifespan between 2000 to 5000 hours. In comparison, the Nutube has a continuous life expectancy of 30000 hours (about 3.4 years) and 2% of the power consumption of a vacuum tube. </span></p><p><span style="font-family: arial;">Korg's Nutube website would be a great place to read up more on this device - </span><span style="font-family: arial;"><a href="https://korgnutube.com/en/">https://korgnutube.com/en/</a></span></p><p><span style="font-family: arial;">This is an ideal kit for a beginner that has some experience in building a kit or two, and comfortable with a soldering iron. The kit as supplied from diyAudio is powered by a 24V wall-wart which makes this a safe project too - no messing around with mains voltage. </span></p><p><span style="font-family: arial;">Put simply, there is an input buffer, followed by the Nutube, and an output buffer.

Music flows with a fluid and noticeable warmth. The effect is not overdone, and detail, speed and dynamics are still delivered intact. Where the B1 Korg stands above its competition, is the dimensionality imparted to the soundstage. Instruments and vocals are able to glow and occupy acoustic space. Many preamps are able to provide sharp and precise imaging and staging, but in a flat and 2-D manner. </span><span style="font-family: arial;">The subtle flavour of romance offered will not suit the cold, hard and clinical listeners out there though. </span></p><p><span style="font-family: arial;">From a quality point of view, I would be comfortable recommending the B1 Korg for use even in entry-level high end systems.</span><span style="font-family: arial;"> </span></p><p><b style="font-family: arial;">Conclusion</b></p><p><span style="font-family: arial;">This is an excellent kit to start off your DIY journey.

Linear power supplies rule because that is what everyone says. Let's have a look at whether there is any wisdom in conventional audiophile thinking?</span></p><p><span style="font-family: arial;">The power supplies on test will be divided into two groups. The first group will be used to power a Melco N100 Digital Music Library, which accepts a 12V power supply. The second group will be used to power a Weiss INT204 USB/SPDIF bridge that accepts a 6-9V power supply. </span></p><p><span style="font-family: arial;">Identical power cords will be used in all cases - an Oyaide Black Mamba. The power supplies will also be switched on one hour before any critical listening is done. Three tracks were played, <i>To whom I give my heart</i><i><b> </b></i>by 2V1G, <i>Colleen's dream</i> by Pat Coil, and <i>Chitlins Con Carne </i>by Kenny Burrell.</span></p><p><span style="font-family: arial; font-size: medium;"><b>12V Power Supplies </b></span></p><p><span style="font-family: arial;"><b>Asian Power Devices DA-48T12 - FOC</b></span></p><p><span style="font-family: arial;">This is the laptop brick power supply that is bundled with the Melco N100. It is rated for 4A of current. Unlike all of the other power supplies on test here, the AC inlet is a figure of eight type instead of an IEC inlet. A suitable converter was used to ensure that the same power cord could be used here. This turned out to be an important factor. Using an aftermarket figure of eight power cord (a more modest model compared to the Oyaide Black Mamba) killed the sonics of the Asian Power Devices brick. </span></p><p><span style="font-family: arial;">The sonics from the stock power supply was passable at their best. Bass lines while smooth and rounded, lacked depth and power. Vocals while warm and pleasant, were also lacking in clarity and definition. The two vocalists in the 2V1G track as an example, could not be clearly distinguished in the soundstage. The better power supplies in comparison clearly placed one singer in the center, and the other, a few feet away on the left. High frequencies were also lacking in crispness, extension and were a bit dull sounding.</span></p><p><span style="font-family: arial;"><b><br /></b></span></p><p><span style="font-family: arial;"><b>Farad Super3 Power Supply - EUR 489</b></span></p><br /><div class="separator" style="clear: both; text-align: left;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiAdTDJAGsyZRjlJTULCKaBC-CMm-bPTFddcTEM6SmI4uFoJkx5BuIO1j_TYO2aqJU4ZUwoS60mRN_yYDwjXe4fmXAmmDomr3dPpO2V4uXbSF88Rr525fhWLesBJ7KFoJWPsSOaqa1PdErwR1GpLSo89aVvtFoxs4RL4ZH8LQ-fHDuHZxOB6eVNu0RH/s1024/farad1.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="576" data-original-width="1024" height="225" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiAdTDJAGsyZRjlJTULCKaBC-CMm-bPTFddcTEM6SmI4uFoJkx5BuIO1j_TYO2aqJU4ZUwoS60mRN_yYDwjXe4fmXAmmDomr3dPpO2V4uXbSF88Rr525fhWLesBJ7KFoJWPsSOaqa1PdErwR1GpLSo89aVvtFoxs4RL4ZH8LQ-fHDuHZxOB6eVNu0RH/w400-h225/farad1.jpg" width="400" /></a></div><br /><div class="separator" style="clear: both; text-align: left;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEikrJnHmPH5izviM6_rfoa7cUyUiR3pynk4BCGO8Yx-A2dukEVAaWiy01wZ5cDEpX-4IWBQuMuvYGoFE6_ussleRyyslND2cf6Ql1f7ohPcAKT79dxx_ZscsZ3HsFY-Tdrtgv3odg8KvnTQtsoVXztTuxBMv_fjaw7YICN3puWeRnw6z3ENmFY3mPYD/s1024/farad2.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="576" data-original-width="1024" height="180" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEikrJnHmPH5izviM6_rfoa7cUyUiR3pynk4BCGO8Yx-A2dukEVAaWiy01wZ5cDEpX-4IWBQuMuvYGoFE6_ussleRyyslND2cf6Ql1f7ohPcAKT79dxx_ZscsZ3HsFY-Tdrtgv3odg8KvnTQtsoVXztTuxBMv_fjaw7YICN3puWeRnw6z3ENmFY3mPYD/s320/farad2.jpg" width="320" /></a></div><br /><p></p><p><span style="font-family: arial;">The Super3 is a double regulated 3A super capacitor linear power supply. A super capacitor is similar in many ways to a battery. Farad claims that the EDCL supercaps used are made for 24/7 operation and long-term reliability. </span></p><p><span style="font-family: arial;">Care has also been taken to reduce power supply noise, with the use of Schottky rectifiers and choke pi-filters. </span></p><p><span style="font-family: arial;">This is a very nice sounding power supply, with very low noise-floor and high levels of detail. It has a very precise sound and good high-frequency extension. Bass power and authority are about on par with the Kingrex PSU Mk II. It reminds me very much of the SOtM sPS-500 but with the low frequency heft to balance things out. </span></p><p><span style="font-family: arial;"><b><br /></b></span></p><p><span style="font-family: arial;"><b>Ferrum Hypsos</b> - <b>EUR/USD 1195</b></span></p><p><span style="font-family: arial;">The Hypsos is an unusual design. Based on a hybrid linear and switching design, the Hypsos promises the best of both worlds - low ripple and noise, as well as fast transient response and high efficiency. Voltage is user selectable from 5-30V with up to 6A of current delivery. This makes the Hypsos powerful enough to power a small NAS or most Intel NUC models. </span></p><p><span style="font-family: arial;"><b><br /></b></span></p><p><span style="font-family: arial;"><b>iFi iPower Elite - USD 299.99</b></span></p><p><span style="font-family: arial;">Featuring iFi's latest Active Noise Cancellation 2 technology, this is one pretty big switched-mode power supply. Shaped very much like a big wedge of cheese, the chassis is a unibody aluminum chassis with fins on the top surface that act as a heatsink.</span></p><p><span style="font-family: arial;">Claiming to have a noise floor of less than 1uv, the iPower Elite is available in 4 models rated at 5V/5A, 12V/4A, 15V/3.5A and 24V/2.5A. Like iFi's other power supplies, adaptors are provided for 2.1mm and 2.5mm tips. A reverse-polarity adaptor is also included for the rare equipment that require center-negative power supplies. </span></p><p><span style="font-family: arial;"><b><br /></b></span></p><p><span style="font-family: arial;"><b>Jay's Audio LPS25VA - USD 168</b></span></p><p><span style="font-family: arial;">This is a super-regulated design derived from Walt Jung's super-regulator circuit. High-quality parts are used like a 25VA Talema mains transformer, Phillips BC reservoir caps, and Panasonic FC decoupling caps. This is a surprise given the modest price tag of the LPS25VA.</span></p><p><span style="font-family: arial;">A front LED panel shows the output voltage, and a trimmer pot on the rear permits fine adjustments to the output voltage.</span></p><p><span style="font-family: arial;">Somehow this power supply failed to float my boat. There was nothing particularly offensive about the sonics, but nothing to write home about either. While this is a more "quiet" sounding power supply compared to the Asian Power Devices and Meanwell bricks, there is a lack of attack and extension on both the low and high frequencies. </span><span style="font-family: arial;"> </span></p><p><span style="font-family: arial;"><b><br /></b></span></p><p><span style="font-family: arial;"><b>Kingrex PSU Mk II - USD 419</b></span></p><p><span style="font-family: arial;">An oldie but goodie. The Kingrex used to be a popular recommendation, but newer products on the market are more sophisticated from a technical point of view. Nevertheless, this model is still worthy of consideration. Featuring a 48VA toroidal transformer and a massive power supply, the Kingrex can be picked up at an affordable price on the pre-owned market.</span></p><p><span style="font-family: arial;">Looking under the hood, this looks like a simple electronic design, with a three-pin regulator, and a variable resistor to set the output voltage.</span></p><p><span style="font-family: arial;">I used my personally constructed DC lead for this, a Neotech PCOCC copper cable. The original lead was long lost in my hi-fi jungle.</span></p><p><span style="font-family: arial;">Listening to the Kingrex brought back good memories. A competent performer in all departments, the Kingrex has good bass, and sparkling extended highs. Cymbals in particular, are reproduced with a crisp strike and decay. The midrange is warm and smooth, but some fine detail is lost. While the bass has weight, it lacked the tightness and slam managed by the best of the power supplies here. </span></p><p><span style="font-family: arial;">Pat Coil's piano playing and the saxophonist on </span><i style="font-family: arial;">Chitlins Con Carne </i><span style="font-family: arial;">lacked some impact and attack as an example. </span><span style="font-family: arial;"> </span></p><p><span style="font-family: arial;"><b><br /></b></span></p><p><span style="font-family: arial;"><b>Kingrex SLAP - USD 450</b></span></p><p><span style="font-family: arial;"></span></p><p><span style="font-family: arial;">Creative naming from Kingrex's marketing department! The SLAP is a Sealed Lead-Acid Battery Power supply unit. Weighing a whopping 7 kg, this brick is fuss-free with a built-in battery management circuit. Some people think that battery power is the only way to be truly isolated from the nasties on the electricity grid.</span></p><p><span style="font-family: arial;"><b><br /></b></span></p><p><span style="font-family: arial;"><b>Meanwell GST60A12-P1J - USD 18</b></span></p><p><span style="font-family: arial;">Meanwell is one of the big names in industrial and commercial power supplies. The model on test here is a 12V/5A brick switched-mode power supply. The Meanwell provided massive bang-for-the-buck. Users of the Melco that are on a tight budget could consider this as a no-brainer upgrade. You get better bass authority and control, clearer and more distinct vocals, and more extended highs. The Meanwell will not pose a threat to any of the better power supplies here, but you can't argue with its value proposition. </span></p><p><span style="font-family: arial;"><b><br /></b></span></p><p><span style="font-family: arial;"><b>Paul Hynes SR4-12 - GBP 342</b></span></p><p><span style="font-family: arial;">The SR4 comes in two models, the SR4-12 which has user-selectable voltage settings from 5 to 12V, and the SR4-19 which has voltage settings from 9-19V.</span></p><p><span style="font-family: arial;">The SR4 utilises a balanced mains isolation transformer and a discrete regulator circuit. Current output is 2A continuous and 20A for transients. The SR4-12 was tested with a silver wire DC lead that may be purchased from Paul Hynes as an option. </span></p><p><span style="font-family: arial;">I enjoyed listening to the SR4-12, although I felt that the sonics were shaped by the silver wire DC lead to a large extent. Quiet and confident-sounding, the Paul Hynes has lovely silky highs that are extended, yet delicate and refined. Authority and control are behind that of the Plixir Elite, and busy mixes did get a little bit messy at times.</span></p><p><span style="font-family: arial;">If your musical diet consists of small-scale classical and jazz pieces, or female vocals, the SR4-12 will really suit you. </span></p><p><span style="font-family: arial;"><b><span><br /></span></b></span></p><p><span style="font-family: arial;"><b><span>Plixir Elite BDC 6A - S$ 1,059.30</span></b></span></p><p><span style="font-family: arial;">Proudly made in Singapore, the Elite BDC features a balanced power transformer and three-stage noise regulation. This is the usual power supply used with the Melco. The Plixir has a firm and neutral sound, with good control over transients. This is a highly resolving power supply and a reference standard for me.</span></p><p><span style="font-family: arial;"><b><br /></b></span></p><p><span style="font-family: arial;"><b>Sean Jacobs DC4 - from GBP 5,400 (no typo!)</b></span></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjRRIWmiirevWoDsbFRlaAfGTHE9lyJZbSctnqlNsgZm_Q3Wj_zcR1qC2Ew8R8czJBrinSIHHu7LNMVIhnzoA8ZuEYP2TOlX2vl1_4odiojh3Bn0S6AXxEfloP7ipRMg1ZMXvXfFvVS4XJij4pmnyScnE30a_P6caXrZzGsxS8PMPzrRpdl7t8wUhn4/s1024/seanjacobsdc4.jpg" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" data-original-height="576" data-original-width="1024" height="225" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjRRIWmiirevWoDsbFRlaAfGTHE9lyJZbSctnqlNsgZm_Q3Wj_zcR1qC2Ew8R8czJBrinSIHHu7LNMVIhnzoA8ZuEYP2TOlX2vl1_4odiojh3Bn0S6AXxEfloP7ipRMg1ZMXvXfFvVS4XJij4pmnyScnE30a_P6caXrZzGsxS8PMPzrRpdl7t8wUhn4/w400-h225/seanjacobsdc4.jpg" width="400" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhFwNzK2l2sdFoestRD2ils32vRPjRHV8sxxFt4jQChfs6YYoyIqROtsY8-7-Ln35H4qp-Px2wwmNrL9kdb--LLgx98rW0_WWLGfpSraie8wCAOmuU6mbMld0mrqrmWyiha1POr6bj1Gd9HD1pNMYw4bFPtwd0lgrcczKL0Xpnhb6ef297Zu-8DVCeD/s1024/seanjacobsdc4_2.jpg" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" data-original-height="576" data-original-width="1024" height="225" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhFwNzK2l2sdFoestRD2ils32vRPjRHV8sxxFt4jQChfs6YYoyIqROtsY8-7-Ln35H4qp-Px2wwmNrL9kdb--LLgx98rW0_WWLGfpSraie8wCAOmuU6mbMld0mrqrmWyiha1POr6bj1Gd9HD1pNMYw4bFPtwd0lgrcczKL0Xpnhb6ef297Zu-8DVCeD/w400-h225/seanjacobsdc4_2.jpg" width="400" /></a></div><br /><span style="font-family: arial;"><br /></span><p></p><p><span style="font-family: arial;"><br /></span></p><p><span style="font-family: arial;"><br /></span></p><p><span style="font-family: arial;"><br /></span></p><p><span style="font-family: arial;"><br /></span></p><p><span style="font-family: arial;"><br /></span></p><p><span style="font-family: arial;"><br /></span></p><p><span style="font-family: arial;">The DC4 is the power supply that people talk about in hushed tones amongst those in the know. Entry to this hallowed circle requires very deep pockets and one additional rack - this power supply is as big as an amplifier.</span></p><p><span style="font-family: arial;">The model I had on hand is able of supplying three 12V supplies, so that brings down the cost of ownership somewhat. Current is limited to 2A per rail due to "CX" module fitted in the regulator module, although this can be bypassed for higher current delivery. The stiff asking price buys you premium parts such as a custom-made toroidal transformer, Neotech OCC internal wiring, Vishay Z-foil naked resistors and Audionote Kaisei capacitors in critical sections.</span></p><p><span style="font-family: arial;">Using a silver wire DC cable from Sean Jacobs, this power supply blew away most of the competition. While this is not the most forceful, incisive or dynamic sounding power supply, the DC4 was able to serve up extremely high amounts of detail while sounding natural and textured. The DC4 nailed timing, sounding just right. It has a level of refinement and quietness that exceeds even the Plixir Elite. However the Plixir has better slam and bass punch, and dishes up a very close level of performance for a lot less money. Like most statement-fi products, whether the price tag is justified depends on personal opinion.</span></p><p><span style="font-family: arial;"><b><br /></b></span></p><p><span style="font-family: arial;"><b>Sbooster BOTW Power & Precision Eco - GBP 260</b></span></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjCSYrakbGkXH6mPn25r4nzH_Aed0smW7vviftpU8qR3RMKCOcY7uH9BRwTpDpHGkXJIpg9FpdwxfgragVqXrSypQkvV6fY_lqIe9G4MUJmye-_PlQe3lNS8tUhTi9zdh1kol5NvzhcEDRJSIj276aKLwGTjYPFJzwYdCi6XZZ88lYJluaa62GHI27z/s1024/sbooster.jpg" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" data-original-height="768" data-original-width="1024" height="300" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjCSYrakbGkXH6mPn25r4nzH_Aed0smW7vviftpU8qR3RMKCOcY7uH9BRwTpDpHGkXJIpg9FpdwxfgragVqXrSypQkvV6fY_lqIe9G4MUJmye-_PlQe3lNS8tUhTi9zdh1kol5NvzhcEDRJSIj276aKLwGTjYPFJzwYdCi6XZZ88lYJluaa62GHI27z/w400-h300/sbooster.jpg" width="400" /></a></div><br /><span style="font-family: arial;"><br /></span><p></p><p><span style="font-family: arial;"><br /></span></p><p><span style="font-family: arial;"><br /></span></p><p><span style="font-family: arial;"><br /></span></p><p><span style="font-family: arial;"><br /></span></p><p><span style="font-family: arial;"><br /></span></p><p><span style="font-family: arial;"><br /></span></p><p><span style="font-family: arial;"><br /></span></p><p><span style="font-family: arial;"><br /></span></p><p><span style="font-family: arial;">The Sbooster supports up to 3A of current and has selectable voltage between 12-13.2V. The Sbooster utilises a dual-stage mains filter and Earth line choke. The unit on test is the original model, which has since been replaced by a MkII version.</span></p><p><span style="font-family: arial;">This is definitely a good step-up from stock power supplies, with a very quiet background and an increase in resolution and control. Bass has less authority than the Plixir and there is subtle grain and splash in vocals and transients. The midrange is also forward, which results in soundstage that is projected forward. </span></p><p><span style="font-family: arial;"><b><br /></b></span></p><p><span style="font-family: arial;"><b>SOtM sPS-500 - USD 500</b></span></p><p><span style="font-family: arial;">Unlike its competitors, the sPS-500 is a switched-mode power supply. It has user-selectable voltages ranging from 7-19V and is capable of supplying up to 5A of current at 12V and 3.3A at 19V. The DC output socket uses a Hirose connector that will test your soldering skills if you intend to construct your own DC cable. As the supplied cable is annoyingly short, you will likely need to order an aftermarket cable.</span></p><p><span style="font-family: arial;">This sPS-500 has a very precise presentation, with very focused imaging and soundstaging. Bass is nimble, tight and deep, but drier compared to most of the other power supplies on test there. Subjectively, music sounds brighter with a noticeably uplift in treble energy and "air". Vocals also have a subtle degree of projection. Music has a very crisp presentation to it, although vocals have more sibilance compared to the rest of the power supplies. </span></p><p><span style="font-family: arial;"><b><br /></b></span></p><p><span style="font-family: arial;"><b>Uptone Audio JS-2 - USD 925</b></span></p><p><span style="font-family: arial;">The JS-2 has two independent and separately adjustable regulated outputs ranging from 5-12VDC with 5A current capability. Uptone took the unusual path of using a choke filtered power supply, an approach that is more commonly used in tube equipment and is less popular due to the increase in weight and cost. You get two power supplies for the price, which makes it easier to swallow.</span></p><p><span style="font-family: arial; font-size: medium;"><b><br /></b></span></p><p><span style="font-family: arial; font-size: medium;"><b>6-9V Power Supplies</b></span></p><p><span style="font-family: arial;"><b>Meanwell GS25A07 - FOC</b></span></p><p><span style="font-family: arial;">This is the stock power supply that is bundled with the Uptone Audio Ultracap. The model is discontinued, but the successor retails for around USD20. Voltage is 7.5V and the current rating is 2.93A. </span></p><p><span style="font-family: arial;"><b><br /></b></span></p><p><span style="font-family: arial;"><b>SOtM mBPs-d2s Battery Power Supply - USD 500</b></span></p><p><span style="font-family: arial;">This is a battery power supply designed to be used specifically for compatible SOtM products, although you could use it with any product that runs on 9V. There are two battery packs that are charged by the supplied switched-mode wall wart. When one battery is exhausted, the mBPs-d2s automatically switched to the other bank. The exhausted battery is then charged. The front panel LEDs indicate which battery is being used, and which battery is being charged or exhausted - all very clever thinking on the part of SOtM.</span></p><p><span style="font-family: arial;"><b><br /></b></span></p><p><span style="font-family: arial;"><b>Uptone Audio Ultracap LPS-1 - USD 395</b></span></p><p><span style="font-family: arial;">Based on super or ultra-capacitors, the LPS-1 was a ground-breaking product at its time. Voltage is selectable between 3.3, 5 and 7V with 1A current rating. Charging and bank-switching is handled by a microprocessor. Some users report that the LPS-1 runs hot and in my experience, it does if you are running it close to the upper limit of its current rating.</span></p><p><span style="font-family: arial;">From a sonic point of view, the LPS-1 sounds pretty good for the price, with a detailed and clear sound. There is a tendency for music to sound bright, with a noticeable high-frequency emphasis, so do match with care. There is a bit more midrange presence compared to the LPS 1.2, with vocals sounding more forward in the soundstage. </span></p><p><span style="font-family: arial;"><b>Uptone Audio Ultracap LPS-1.2 - USD 435</b></span></p><p><span style="font-family: arial;">The successor to the LPS-1 covers voltages between 5 and 12V. Current rating at all voltages is 1.1A. New output voltage regulators are used in parallel to reduce noise as well as output impedance. Think of this as an improved LPS-1, with much improved low frequency punch and tightness. Imaging and staging is also more precise, with improved depth. Considering the small difference in price, the LPS 1.2 is definitely the one to go for. </span></p><p><span style="font-family: arial;">To be continued ... </span></p><p><span style="font-family: arial;"> </span></p>Eric Tehhttp://www.blogger.com/profile/05157135145227727200noreply@blogger.com1tag:blogger.com,1999:blog-684396141123606281.post-69650909221335992992022-01-05T05:34:00.003-08:002022-01-05T05:34:51.454-08:00WFH Special #1 - Creative SXFI Gamer USB-C Gaming Headset<p><span style="font-family: arial;"><b>Introduction</b></span></p><p><span style="font-family: arial;">The SXFI Gamer is a wired </span><span style="font-family: arial;">USB-C</span><span style="font-family: arial;"> </span><span style="font-family: arial;">gaming headset with Super X-Fi technology and a flexible goose neck microphone (Creative Technology refers to this as "CommanderMic"). </span></p><p><span style="font-family: arial;">I am not suggesting that you play computer games during office hours while on your work-from-home stints. Instead, use your SXFI Gamer for conference calls, listening to music, and gaming sessions. You won't get the evil eye from your spouse too when justifying your purchase.</span></p><p><span style="font-family: arial;">The recommended retail price is very reasonably priced at S$ 179.</span></p><p><span style="font-family: arial;"><b>Description</b></span></p><p><span style="font-family: arial;">Super X-Fi is Creative's proprietary technology that seeks to create a life-like soundstage that is akin to the music experience of listening to speakers. Regular headphone users will know that the soundstage is trapped in your head, which greatly diminishes the realism of the listening experience. </span></p><p><span style="font-family: arial;">To use Super X-Fi, you need to download the SXFI App on your phone, create an account and start the process of head and ear mapping. This involves using your phone camera to take pictures of your face and ears. </span></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEjCvnFETTNYuM89hE8qFYIXEiLanGTITwVmXVqGqLVsL4y2wBLL3YVbiU0v4c-Vze4nkzrqTe5Els3s2Gpe-6ovrjao6doXPw0JTWhPGlYHyy0ka2mHKLoF3QDuA3P_GRzPUmiAboureWkL1tcP6r6d33ui6XhYed-Ajt74gnirj1vMwLWNEwHbXtFX=s1200" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1200" data-original-width="568" height="640" src="https://blogger.googleusercontent.com/img/a/AVvXsEjCvnFETTNYuM89hE8qFYIXEiLanGTITwVmXVqGqLVsL4y2wBLL3YVbiU0v4c-Vze4nkzrqTe5Els3s2Gpe-6ovrjao6doXPw0JTWhPGlYHyy0ka2mHKLoF3QDuA3P_GRzPUmiAboureWkL1tcP6r6d33ui6XhYed-Ajt74gnirj1vMwLWNEwHbXtFX=w302-h640" width="302" /></a></div><br /><span style="font-family: arial;"><br /></span><p></p><p><span style="font-family: arial;">The personalised settings are then downloaded into a SXFI certified headphone, like the SXFI Gamer.</span></p><p><span style="font-family: arial;">The package includes the headphone set, the detachable CommanderMic, and both a USB C and 3.5 mm audio cable. A USB-C to USB adapter is thoughtfully provided in case your computer only has normal USB ports.</span></p><p><span style="font-family: arial;">The 3.5mm audio cable looks like any stock cable, while the USB C cable is Kevlar jacketed which should provide long and reliable use. </span><span style="font-family: arial;">The USB cable is unfortunately very sensitive to microphonics and friction between the cable and your clothes will be picked up and annoyingly amplified. </span><span style="font-family: arial;"> </span></p><p><span style="font-family: arial;">The headset comes with large and heavily padded over-ear pads which are mounted in a plastic frame that allows a small amount of swivel. Combined with the low-pressure headband, the SXFI Gamer is very comfortable to wear for extended periods of time. Noise isolation is also decent, with both little noise making it through, or being leaked out. </span><span style="font-family: arial;">The headband also has a numbered scale to make adjustments both easy and repeatable - something I wished that other manufacturers would do. Both headphone cups are equipped with an RGB ring.

A red LED is placed at the microphone inlet so positioning is easy. The LED flashes when the microphone is muted, which is a nice touch.</span></p><p><span style="font-family: arial;">I used the SXFI Gamer via USB on both a Windows 10 and macOS Catalina computer without any issues. I also did some testing via the 3.5mm jack on a variety of mobile phones and DAPs. </span></p><p><span style="font-family: arial;"><b>Sound Quality</b> </span></p><p><span style="font-family: arial;">Tonally, these headphones are close to neutral with good levels of detail. The 50mm drivers impart a solid and hefty feel to bass lines. However, the SXFI Gamer avoids the thick and heavy handed approach, so you will not get overblown or exaggerated bass. Bass is tight and tuneful, and powerful when the source material dictates it. If you like a bass-heavy presentation, you can always fix that through the EQ function.</span></p><p><span style="font-family: arial;">Vocals are reproduced clearly and with minimal amount of grain. High frequencies have sparkle and extension, and cymbals have a crisp and clear response. There is a hint of splash and confusion during heavy mixes, but this is to be expected given the modest price of the SXFI Gamer. Sonics wise, these headphones perform way above the competition in the same price bracket.</span></p><p><span style="font-family: arial;">Depressing the SXFI button toggles between the normal, Super X-Fi and Battle Mode. I found the Super X-Fi mode to work best on 5.1 and 7.1 material. At its best, this imparted a spacious and more speaker-like experience. However on 2 channel material, the effect is somewhat unnatural and hollow. Similarly, Battle Mode did its job on first-person shooters by altering the frequency curve to accentuate footsteps and suppressing the rest of the audio-band. While you can hear your enemies better, this came at the expense of an unnatural tone that made the experience less immersive and realistic. </span></p><p><span style="font-family: arial;">The surprise star of the show is the CommanderMic. The microphone is very clear and the software does a decent job of suppressing ambient noise. However, t</span><span style="font-family: arial;">he microphone is highly directional and has to be pointed directly at your mouth for best results.</span><span style="font-family: arial;"> </span><span style="font-family: arial;">I often preferred using these headphones for conference calls over my professional headsets from big-name manufacturers. </span></p><p><span style="font-family: arial;">The SXFI Gamer sounds almost identical using the 3.5mm cable, with results varying only slightly depending on the equipment used. These headphones are easy to drive and sound comfortable powered through a mobile phone jack. However, you will lose a lot of functionality as none of the buttons nor sound modes will work. Nevertheless this is a good option so that you can take the SXFI Gamer on a business trip and use them on the road or airplane with your mobile phone or DAP.</span></p><p><span style="font-family: arial;"><b>Conclusion</b></span></p><p><span style="font-family: arial;">Equally comfortable doing multiple duties as a gaming or office headset, or music listening for the audiophile on a budget, the SXFI Gamer offers </span><span style="font-family: arial;">outstanding value at its recommended retail price of S$ 179. </span></p><p><span style="font-family: arial;">At the time of writing, they are being offered at a discounted price of S$89 which makes this an absolute no brainer - <b>Best Buy.</b></span><span style="font-family: arial;"> </span></p><p><span style="font-family: arial;"><b><br /></b></span></p><p><span style="font-family: arial;

Minutes later, Joe appeared in a huff and drenched in perspiration - the humid tropical weather was especially unkind to office workers in their impractical attire.</span></p><p><span style="font-family: arial;">"Took a leisurely walk here Joe ?" Mei commented sarcastically before defusing the sharp edge of her words with the sweetest smile ever.</span></p><p><span style="font-family: arial;">Joe ignored her remark and quietly opened the door, heading straight for the shop that carried Devialet products. Mei had tasked him to find a suitable stereo system for her and he thought this fit the bill even though it was too much of a compromise by his exacting audiophile standards.</span></p><p><span style="font-family: arial;">Mei and Joe were welcomed into the shop (Joe was a regular customer there) and after some refreshments, the salesperson ran them through the features of the Devialet Expert Pro amplifier. Mei sat down on the sofa with Joe standing behind her. She scrolled through the iPad lying on the sofa and within a minute, her favourite tunes were playing sweetly through the speakers in front of her. She twirled the knob of the remote control a few times and nodded approvingly. After a few tracks, she got up and walked over to the Devialet amplifier that was sitting on the top shelf of the component rack. She brushed her long slender fingers on the beautifully chromed chassis. It looked like a futuristic slab of metal, with just a single small circular window breaking the uniformity of the top panel.</span></p><p><span style="font-family: arial;">"This is a very beautiful piece of art. Will you help me set it up ?" Mei smiled at the salesperson with her dimples barely showing. </span></p><p><span style="font-family: arial;">"Ah! Of course Miss. We will set up the whole system for you. If you have an existing music library your boyfriend can help you connect it - it's really easy." The salesperson could smell the scent of a pending sale and the soon-to-be-earned commission was already warming the cockles of his heart.</span></p><p><span style="font-family: arial;">"Boyfriend? Please!" Mei dismissively replied while rolling her eyes disapprovingly. Joe blushed at both the salesperson's words and the sting of Mei's response.</span></p><p><span style="font-family: arial;">"It's a digital amp and you are paying a premium for a lifestyle product!" Joe protested at Mei's impulsive decision. Mei ignored Joe and continued to stroke the Devialet lovingly.</span></p><p><span style="font-family: arial;">Thankfully, the salesperson managed to close the deal and the Devialet was delivered promptly to Mei's home with other components to make up her minimal and very tasteful music system.</span></p><p><span style="font-family: arial;"><b>Introduction</b></span></p><p><span style="font-family: arial;">Mei and Joe are fictional characters, but there are many music lovers like Mei. They want a beautiful and good-sounding amplifier that can fit nicely into a modern home. Too many audio components look like something from a mad scientist's laboratory, or the control panel of a nuclear reactor. </span></p><p><span style="font-family: arial;">My very first experience with Devialet dates back many years ago when the D-Premier was first launched. A fellow audiophile was very eager for me to listen to it, and he turned up at my doorstep with a large flat box under one arm (don't try this with conventional amplifiers!). It was an impressive experience, with a laidback and slightly warm sound that was more than powerful enough to power my speakers then - a pair of Focal Diablo Utopia bookshelf speakers. Positive impressions aside, there were some glaring omissions in my opinion, the prime ones being unstable wi-fi streaming and a lack of a USB port. </span></p><p><span style="font-family: arial;">Was the D-Premier equal to my stack of components which were of equivalent value? Like a directionless corporate meeting, we respectfully agreed to disagree. He preferred the </span><span style="font-family: arial;">D-Premier</span><span style="font-family: arial;">, while I preferred my clumsy stack of components. He mischievously reminded me that the </span><span style="font-family: arial;">D-Premier </span><span style="font-family: arial;">was cheaper by a significant margin once I took into account the many footers, cables, power cords and rack space involved with my traditional stack.</span></p><p><span style="font-family: arial;">The D-Premier cost close to S$ 20,000 when it was first released in Singapore. Thankfully, Devialet has worked hard over the years and the entry-level model (the subject of this review), the Expert 140 Pro is much more affordable.</span></p><p><span style="font-family: arial;"><b>Description</b></span></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-1K5x1ojdynk/X1DIh348PHI/AAAAAAAACYM/RvciH97fpGAxhDHTwpYc9RikA48dGlNWgCNcBGAsYHQ/s1200/devialet1.JPG" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="800" data-original-width="1200" height="416" src="https://1.bp.blogspot.com/-1K5x1ojdynk/X1DIh348PHI/AAAAAAAACYM/RvciH97fpGAxhDHTwpYc9RikA48dGlNWgCNcBGAsYHQ/w625-h416/devialet1.JPG" width="625" /></a></div><br /><p></p><p><span style="font-family: arial;">The Expert 140 Pro retains the sleek lines of the D-Premier. It is sexy enough to elicit envious glances from the most jaded audiophile. It has a more than passing resemblance to a high-end bathroom scale, and can even be mounted on the wall if you so desire.</span></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-m5FsCoGmwXk/X1DIsIfn2BI/AAAAAAAACYQ/YcaWIWj0cHEAqmk9IziMNVF9VTq6XkNNACNcBGAsYHQ/s1200/devialet2.JPG" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="800" data-original-width="1200" height="416" src="https://1.bp.blogspot.com/-m5FsCoGmwXk/X1DIsIfn2BI/AAAAAAAACYQ/YcaWIWj0cHEAqmk9IziMNVF9VTq6XkNNACNcBGAsYHQ/w625-h416/devialet2.JPG" width="625" /></a></div><p></p><p><span style="font-family: arial;">A small port window shows various information including volume, source, and the status of SAM, and network connections. A single button powers up and shuts down the unit, while a sleek remote control controls commonly used functions (or as customised by the user).</span></p><p><span style="font-family: arial;">Beauty here is not merely skin-deep. The Expert 140 Pro packs impressive amounts of technology and integration. Apart from being a powerful integrated amplifier, it also contains a DAC, phono stage (both MM and MC) and streamer. </span></p><p><span style="font-family: arial;">The most controversial design point is that everything is handled in the digital domain. In the case of the phono stage, or analog input, the signal is converted to digital using a high quality A/D converter. Listening to your records after it has been digitised ? Sacre Bleu ! An optimist would of course focus on the benefits of having the signal in the digital domain, including the ability to process the signal using powerful DSP. Devialet is able to do this for both the partnering record cartridges (RAM) and speakers (SAM). The digital heavy lifting is carried out using a Quad-core 1 GHz CPU and 2 X SHARC 400 MHz DSP units.</span></p><p><span style="font-family: arial;">Despite the compact form factor, the Expert 140 Pro packs a powerful punch. Power output is 140 W per channel into 6 ohms. Amplification is achieved with a hybrid design that combines a Class A amplifier (providing voltage amplification) with Class D modules (providing current). In a way, this concept is similar to the current-dumping design launched by Quad in 1975 which combined a Class A amplifier with "current-dumping" transistors to supply the necessary current. Class A designs are required to dissipate tremendous amounts of heat and a design that could deliver power equivalent to the Devialet would be massive and put out enough heat to warm a small room! </span></p><p><b style="font-family: arial;">RAM and SAM</b></p><p><span style="font-family: arial;">Record Adaptive Matching (RAM<span style="font-size: x-small;">Ⓡ</span>) is available in the Expert 220 Pro upwards and the Expert 140 Pro only allows a choice between MM/MC and adjustment of sensitivity. RAM allows the user to choose more than 256 combinations of resistance and capacitance, as well as a choice of equalisation curve. </span></p><p><span style="font-family: arial;">Speaker Adaptive Matching (SAM</span><span style="font-family: arial; font-size: x-small;">Ⓡ</span><span style="font-family: arial;">) is a complex compensation model that attempts to correct sub-optimal speaker behaviour. Devialet measures the speaker in question to create a map of more than 60 parameters. The model is derived from measurement of the crossover network, speaker driver displacement, deformation, maximum displacement, speed and acceleration. Speaker models are continuously added to the SAM database, and the current database stands at more than 900 models. Conveniently, both my Vivid Giya G4 and Tannoy Kensington GR speakers are listed in the database. </span></p><p><span style="font-family: arial;">A worthy mention is that SAM allows extension of your low-frequency response, with sensible protection built-in to prevent you from blowing up your speakers. It can be switched in and out on the fly using the remote control. By configuring your remote, it is possible to adjust the level of SAM correction from 0 % to 100 %.</span></p><p><span style="font-family: arial;"><b>Configurator</b></span></p><p><span style="font-family: arial;">An online configurator allows you to set up your Devialet according to your preferences. You can configure your inputs to be either digital or analog (either line-level or phono), and apply SAM, and phono settings too. </span></p><p><span style="font-family: arial;">This is just scratching the surface of what the configurator allows you to do. You can also (this is just a shortlist of features available) customise your remote control buttons, adjust the sampling rate of the ADC for analog inputs, set individual sensitivity levels, and adjust the maximum power output allowable from the unit. </span></p><p><span style="font-family: arial;">The configuration file is then saved onto an SD card which is inserted into a slot at the back of the amplifier. You could create multiple configuration files to be saved on different SD cards should you wish to show off your amplifier in another person's system. </span></p><p><span style="font-family: arial;"><b>Operation and Ease of Use</b></span></p><p><span style="font-family: arial;">Getting the Expert 140 Pro up and running was quite easy, save for the scare I got from the non-responsive remote. It turned out that the installed batteries were dead even though my unit was brand new. </span></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgrUzernW_A9z3ksGTFaQ7SDsWxD0kAPTDH1rFfxHRY-zMm3pZ1Sp0ZCD5T22-ByUmbQylWFU37ZCRVww3bK_C-JDDFFpKRWzF02zdbAxP8-oE62kt6O2wT6c7PWFzXXT2Qp1RDvtHzMb8b/s1200/devialet3.JPG" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="800" data-original-width="1200" height="416" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgrUzernW_A9z3ksGTFaQ7SDsWxD0kAPTDH1rFfxHRY-zMm3pZ1Sp0ZCD5T22-ByUmbQylWFU37ZCRVww3bK_C-JDDFFpKRWzF02zdbAxP8-oE62kt6O2wT6c7PWFzXXT2Qp1RDvtHzMb8b/w625-h416/devialet3.JPG" width="625" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgOXLHhn_ebWavPJ1kW3qfk8sU6O3fgXHymgv1O38EZuuExIrPvMCuMMl-flR7qhKSPaG48WXhx1cTGaGWCphJawXn23pJ6TY4f4uyrxo5pIG9Uhq7CemJHFAEXc7EhyphenhyphenbFST22tMu4rHQdE/s1200/devialet5.JPG" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="800" data-original-width="1200" height="416" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgOXLHhn_ebWavPJ1kW3qfk8sU6O3fgXHymgv1O38EZuuExIrPvMCuMMl-flR7qhKSPaG48WXhx1cTGaGWCphJawXn23pJ6TY4f4uyrxo5pIG9Uhq7CemJHFAEXc7EhyphenhyphenbFST22tMu4rHQdE/w625-h416/devialet5.JPG" width="625" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-EQlcVPIBjM8/X1DJWXHqPKI/AAAAAAAACY0/qhe5fYvA-6cF-tWIyxrQcn_ciT84TriGgCNcBGAsYHQ/s1200/devialet4.JPG" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="800" data-original-width="1200" height="416" src="https://1.bp.blogspot.com/-EQlcVPIBjM8/X1DJWXHqPKI/AAAAAAAACY0/qhe5fYvA-6cF-tWIyxrQcn_ciT84TriGgCNcBGAsYHQ/w625-h416/devialet4.JPG" width="625" /></a></div><br /><span style="font-family: arial;"><br /></span><p></p><p><span style="font-family: arial;">The compact dimensions do require you to use a power cord with a slim IEC and banana plug terminated speaker cables. In an all-time first, an entry level Audioquest power cord is supplied in the box. In case you insist on using your massively sized power cords, a removable rear plate allows you to do this, losing a bit of stylishness in the process.</span></p><p><span style="font-family: arial;">I never got the Devialet to stream from a DLNA server source, and neither did I install Devialet Air (the companion streaming software) as this runs on a personal computer (which I do not use in my main system). Instead, I used the Devialet as a Roon endpoint where it worked seamlessly. You can also use Airplay and Spotify Connect if you want to.</span></p><p><span style="font-family: arial;">I did have the odd occasion where the Devialet failed to detect the SD card upon start-up. However, powering the unit down and re-inserting the SD card solved this. I found it odd that Devialet used such a primitive method of configuring the unit when everything else about the unit is technologically light-years ahead of the competition. The configuration file is a text file that can actually be viewed and edited, which seems dated. It would have been nice to be able to configure the Devialet using an app instead. Instead, the free app works as a substitute for the remote control. </span></p><p><span style="font-family: arial;">My remote also had an issue with batteries, eating up fresh alkaline batteries every 2-3 months on average. No wonder, the factory-supplied batteries were flat on arrival! I've read of other users having similar issues, and this apparently can be fixed by the factory. </span></p><p><b style="font-family: arial;">Sound Quality</b></p><p><span style="font-family: arial;">The Devialet appeals as a lifestyle product and brings with it the misconceptions of an overpriced and inferior product. Actual use (I've had my set for more than two years) proves that this is a highly versatile product that is a viable and attractive alternative to a stack of components with spaghetti cabling everywhere! I have brought the Devialet along to listening sessions in other setups where they have always acquitted themselves, even against very expensive equipment.</span></p><p><span style="font-family: arial;">The Devialet does have a subtly sweet and rich tone that is pleasant and inviting. The Class D detractors would have to leave in disappointment at this juncture. The midrange in particular is sweet, smooth and laidback. The bass quality is good, with power and a full textured midbass. In fact, you could argue that the Devialet takes the polite path rather than a sharp, or hyper analytical route. The high frequencies are also cleanly reproduced, without any noticeable evidence of roll-off or anomalies from the low-pass filter required for Class D designs to filter out ultra-sonic noise.</span></p><p><span style="font-family: arial;">I would rate the Devialet's performance as reasonable for the price. However, enabling SAM lifts it up significantly. Apart from the very obvious boost in bass extension and power, there is an increase in focus and coherency that makes it very hard to revert back to SAM-less listening. Play it again Sam!</span><span style="font-family: arial;"> </span></p><p><b style="font-family: arial;">Conclusion</b></p><p><span style="font-family: arial;">The Devialet is a superb all-in-one that demonstrates that convenience need not come at the expense of sound quality. It's a pity that traditionally-minded audiophiles may not give the Devialet due consideration. </span></p><p><span style="font-family: arial;">With shrinking living spaces in Asia, this is the perfect product that ticks all the boxes :- looks, convenience, quality and price. Some may disagree that the Devialet is an affordable product, but I am convinced based on the many boxes it replaces, and the outstanding sound quality it delivers - <b>Highly Recommended</b>. </span></p><p><b style="font-family: arial;">Epilogue</b></p><p><span style="font-family: arial;">Mei sat gracefully on her sofa, listening to music from her new sound system. Joe had managed to convince her to install the Expert 140 Pro amplifier on top of her cantilevered TV rack. Discrete cabling ran to two very slim floorstanding speakers. The system was a perfect foil to Mei's character - graceful and elegant. </span></p><p><span style="font-family: arial;">Her music collection had been ripped and stored on a dedicated Intel NUC PC that functioned as a Roon server. Joe had also subscribed to Tidal in case Mei wanted to explore new music just like she did when she came over to his home. </span></p><p><span style="font-family: arial;">Standing up, Mei surveyed the very neat job that Joe had done in arranging everything. Her long flowing white dress showed off her slim waist and she glowed like an angel. Joe's heart skipped a beat and he bit his lower lip hard.</span></p><p><span style="font-family: arial; font-size: x-small;"><br /></span></p><p><span style="font-family: arial; font-size: x-small;"><b>Devialet Expert Pro 140 Amplifier</b></span></p><p><span style="font-family: arial; font-size: x-small;">Price : S$ 8,990</span><span style="font-family: arial;"> </span></p><p><span style="font-family: arial;"> </span></p><p><span style="font-family: arial;"><br /></span></p><p><span style="font-family: arial;"> </span></p><p><br /></p><p><br /></p>Eric Tehhttp://www.blogger.com/profile/05157135145227727200noreply@blogger.com1tag:blogger.com,1999:blog-684396141123606281.post-27487171194176495632021-06-19T03:25:00.003-07:002021-07-30T19:03:54.441-07:00Markaudio-SOTA Tozzi One Speaker Kit<p><span style="font-family: arial;"><b>Introduction</b></span></p><p><span style="font-family: arial;">The Tozzi One speaker kit is likely the easiest speaker kit on the market. I assembled it in an hour, half of which was spent looking for my tools, and cleaning up. This is the perfect kit for beginners as there is no soldering involved - all you need is a screwdriver. </span></p><p><span style="font-family: arial;">The kit costs USD 395 per pair if purchased direct from the manufacturer, but it can sometimes be found cheaper from other merchants. </span></p><p><span style="font-family: arial;"><b>Description</b></span></p><p><span style="font-family: arial;">Based on their in-house CHN 50 full-range driver, the Tozzi One is built around an ABS and fiber-reinforced cabinet. </span></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjf6uz_W51wiJ6aUBkGIpQkiRdWSXeJj_FVeWd2Z4e5bqwHjSccoELuZ-vtkvViWwIJp-JrdN_eoxomV3wWmDytL8eXhiMtF45LCwMGZMf1l5m0kWxT4GT070TZcXV8gt8ABK-t8v_XCE3c/s2048/20210619_143307.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1536" data-original-width="2048" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjf6uz_W51wiJ6aUBkGIpQkiRdWSXeJj_FVeWd2Z4e5bqwHjSccoELuZ-vtkvViWwIJp-JrdN_eoxomV3wWmDytL8eXhiMtF45LCwMGZMf1l5m0kWxT4GT070TZcXV8gt8ABK-t8v_XCE3c/w640-h480/20210619_143307.jpg" width="640" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-2nw_FUDypCA/YM3KOtOu2yI/AAAAAAAACiQ/Us-D_X-pCHQ-Plq3w-XdoW8ZC8bb2--nwCNcBGAsYHQ/s1200/cabinet.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="900" data-original-width="1200" height="480" src="https://1.bp.blogspot.com/-2nw_FUDypCA/YM3KOtOu2yI/AAAAAAAACiQ/Us-D_X-pCHQ-Plq3w-XdoW8ZC8bb2--nwCNcBGAsYHQ/w640-h480/cabinet.jpg" width="640" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-6yAHRrEGY6o/YM3KOcM_O7I/AAAAAAAACiU/jVqjPGB5bmIJR6UBoLvZUsYVelHneq67QCNcBGAsYHQ/s1200/driver.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="900" data-original-width="1200" height="480" src="https://1.bp.blogspot.com/-6yAHRrEGY6o/YM3KOcM_O7I/AAAAAAAACiU/jVqjPGB5bmIJR6UBoLvZUsYVelHneq67QCNcBGAsYHQ/w640-h480/driver.jpg" width="640" /></a></div><p><span style="font-family: arial;"><br /></span></p><p><span style="font-family: arial;">The driver is mounted in a shallow wave-guide, while the cabinet is rear-ported. Sensitivity is rated at 85 dB, and impedance at 6 ohms. The anechoic frequency response is specified at 80 Hz - 22 kHz (+/- 6 db). The cabinet measures 200 x 126 x 200 mm, and weighs 1.42 kg. The cabinet is angled up slightly, so you should be fine listening to it in the near-field while placed on your desk. </span></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-TmI1xQ0Xcl8/YM3KxYapgRI/AAAAAAAACi0/ov_vPI4jJAowhXsxBUdMX0T_NeTVjaa5gCNcBGAsYHQ/s1200/accessories.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="900" data-original-width="1200" height="480" src="https://1.bp.blogspot.com/-TmI1xQ0Xcl8/YM3KxYapgRI/AAAAAAAACi0/ov_vPI4jJAowhXsxBUdMX0T_NeTVjaa5gCNcBGAsYHQ/w640-h480/accessories.jpg" width="640" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><br /></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-C0xXrP03Cxc/YM3KoqjzTGI/AAAAAAAACis/JNE7RR-JgGkYX9noXnHKcZxDlETxFQ7hgCNcBGAsYHQ/s1200/cabinet2.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="900" data-original-width="1200" height="480" src="https://1.bp.blogspot.com/-C0xXrP03Cxc/YM3KoqjzTGI/AAAAAAAACis/JNE7RR-JgGkYX9noXnHKcZxDlETxFQ7hgCNcBGAsYHQ/w640-h480/cabinet2.jpg" width="640" /></a></div><br /><span style="font-family: arial;">The waveguide has a textured finish, while the sides of the cabinet are finished in a faux leather wrap. </span><p><span style="font-family: arial;">Assembly is straightforward enough. The instructions were in Japanese, but the diagram is clear enough to figure out. </span></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-h3PvbvlU-Rc/YM3KcQ7vY8I/AAAAAAAACig/nVpmSNeRw7sSRjldrK2l53K8HzMJ1YCMACNcBGAsYHQ/s1200/instructions.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="856" data-original-width="1200" height="456" src="https://1.bp.blogspot.com/-h3PvbvlU-Rc/YM3KcQ7vY8I/AAAAAAAACig/nVpmSNeRw7sSRjldrK2l53K8HzMJ1YCMACNcBGAsYHQ/w640-h456/instructions.jpg" width="640" /></a></div><br /><span style="font-family: arial;"><br /></span><p></p><p><span style="font-family: arial;">A thin gasket is placed between the front baffle and the speaker driver. The driver is held in place with five hex nuts. The supplied wiring is terminated in push-on terminals and o-rings, so you just need to connect them to the speaker driver and supplied five-way binding posts. The rear panel foam needs to be affixed using the supplied double-sided tape. Install the gasket into the rear panel groove, and attach it to the speaker cabinet with screws. That's it! Building and programming a custom keyboard is far more challenging than this. </span></p><p><span style="font-family: arial;">The beauty of full-range driver designs is that there is no crossover to mess around with. From a technical viewpoint, you get the best possible coherence from using a single driver and higher efficiency and purity from skipping the passive crossover. There is no free lunch though. Asking a driver to cover the whole frequency range results in uneven response. Most designs have to rely on complex cabinet designs with some form of a back-loaded horn to get usable bass output. </span></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-wDEKnOE5li0/YM3K7IxCnyI/AAAAAAAACjE/M8GV0uf0hZcMB3AEnVGUBFrHXIIhZiEawCNcBGAsYHQ/s1200/speaker%2Bfinal.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1200" data-original-width="900" height="640" src="https://1.bp.blogspot.com/-wDEKnOE5li0/YM3K7IxCnyI/AAAAAAAACjE/M8GV0uf0hZcMB3AEnVGUBFrHXIIhZiEawCNcBGAsYHQ/w480-h640/speaker%2Bfinal.jpg" width="480" /></a></div><br /><span style="font-family: arial;"><b>Sound Quality</b></span><div><span style="font-family: arial;"><b><br /></b></span></div><div><span style="font-family: arial;">Straight out of the box, the Tozzi One has a clear and engaging sound, but with some rough edges. A few hours of run-in sorts that out nicely.</span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;">As expected from a full-range driver speaker, you get a lovely transparent and coherent sound. The Tozzi One sounds bigger than it looks although the very limited low-frequency output and extension makes it more suited for background listening in a large room, or listening in the near-field. In a large room, you definitely need to pair this with a subwoofer. </span><span style="font-family: arial;"> </span></div><div><span style="font-family: arial;"><br /></span><div><span style="font-family: arial;">Fast forward a month later, and the Tozzi One has had everything thrown at it while it sat on my computer and work desk - gaming sessions, background music, serious listening sessions, etc. As desktop speakers and with proper amplification, the Tozzi One will eat your computer speakers for lunch. I paired them with a spare Kingrex T20U amplifier that I happened to have lying around. The Kingrex delivers 10W per channel into a 4 ohm load and is enough to drive the Tozzi One to fairly loud levels for near-field listening purposes. I found it to have enough grunt to make explosions, gunshots, and orchestral crescendos equally satisfying. The rest of the frequency range was handled quite well without the midrange honk or peaky top-end that I sometimes hear from full-range drivers. In fact, the midrange is laidback and on the warm side of neutral. </span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;">Where the Tozzi One really nails it is staging and imaging that is both spacious and pin-point. There is plenty of soundstage width, depth, and a good sense of dimensional layering. </span></div><div><span style="font-family: arial;"> </span></div><div><span style="font-family: arial;"><b>Conclusion</b></span></div><div><span style="font-family: arial;"><b><br /></b></span></div><div><span style="font-family: arial;">The Tozzi One is an excellent addition to my work desk. With the present world situation, this may be just the thing you need to preserve your sanity during long work-from-home stints. It may need more effort to set up than the usual powered speaker suspects, but it is well worth it.</span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial; font-size: x-small;"><b>MarkAudio-SOTA</b></span></div><div><span style="font-family: arial; font-size: x-small;">http://markaudio-sota.us/</span></div><div><span style="font-family: arial; font-size: x-small;">Price : USD 395 per pair<br /></span><p><br /></p></div></div>Eric Tehhttp://www.blogger.com/profile/05157135145227727200noreply@blogger.com1tag:blogger.com,1999:blog-684396141123606281.post-33879213658929204512021-05-26T00:29:00.008-07:002021-06-13T00:55:35.072-07:00Elekit TU-8600R Integrated Amplifier<span style="font-family: arial;"><b>Introduction</b></span><div><span style="font-family: arial;"><b><br /></b></span></div><div><span style="font-family: arial;">Problem Statement - You want a quality integrated tube amplifier, but no means to afford one. No problem, just build your own ! Assuming you have decent soldering skills, and are not instruction-intolerant (sadly, that rules out my teenage daughter), the Elekit TU-8600R lets you enjoy quality on the cheap. You will need about four full days to build one, but the effort is well worth it.</span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;"><b>Description</b></span></div><div><span style="font-family: arial;"><b><br /></b></span></div><div><span style="font-family: arial;">The Elekit TU-8600R is a 300B single-ended integrated tube amplifier kit from the nice folks at Elekit of Japan. The TU-8600R is neither a basic kit nor design, and has parts quality and design features found in high-end models.</span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;">The power transformer is a high-quality R-core type, with low magnetic flux leakage. The solid state rectification uses Schottky fast recovery diodes. The power supply circuit includes ripple filters and plenty of regulation stages. An active automatic bias adjustment system means no fiddling with bias pots, and optimal sound quality at all times.</span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;">Parts quality is generous with plenty of Japanese branded resistors and capacitors. The PCB thoughtfully provides sufficient space for you to install large boutique coupling capacitors too. After all, isn't that the whole point of DIY, the freedom to express yourself ?</span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;">The TU-8600R's circuit is based on a single 12AX7 input tube, which then feeds dual 12AU7 tubes. The latter's two triode sections are wired in parallel to drive the 300B power tube. The output transformer has speaker taps for both low and high impedance speaker loads (selectable by a switch on the rear). A headphone socket allows you to enjoy your Elekit with your favourite pair of cans. Jumpers on the PCB allow you to adjust the headphone output level, and the colour of the power LED.</span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;">Although the </span><span style="font-family: arial;">TU-8600R is an integrated amplifier, there is only one set of RCA inputs. This could be a deal-breaker for some, although you could purchase or build an input switching box to get around this. </span></div><div><span style="font-family: arial;"><b><br /></b></span></div><div><span style="font-family: arial;"><b>Build Experience</b></span></div><div><span style="font-family: arial;"><b><br /></b></span></div><div><span style="font-family: arial;">Elekit gets first prize for having the best instructions I've ever received with an audio-oriented kit. The instructions rely on very clear diagrams and steps to guide you every step of the way. The PCB is marked clearly and even reminds you when components are required to be installed on to the reverse side of the board. Plenty of due care and consideration went into ensuring that the assembly is as painless as possible. </span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;">The sheer parts count and complexity of the PCB makes this project highly unsuitable for a first-time build. The soldering of the transistors was the most delicate part of the build, as the solder pads are dangerously close. I would also highly recommend that a temperate controllable iron be used. </span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;">In my case, I chose to upgrade the stock resistors to Takman Carbon film ones, and the coupling capacitors to Amtrans AMCY Golden Black. I also bypassed the volume pot and wired the input jacks directly to the main PCB. The input sensitivity will be high, but if you are able to adjust the output level on your source (e.g. a DAC with volume control), you should be fine. </span></div><div><span style="font-family: arial;"><br /></span></div><div><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto;"><tbody><tr><td style="text-align: center;"><a href="https://1.bp.blogspot.com/-tP3CSNCU-qU/YLQkv3atvNI/AAAAAAAACgc/NjrwTdn5eZoAg2aJKqdumiwV3k61yNYPACNcBGAsYHQ/s1200/elekit1.jpg" style="margin-left: auto; margin-right: auto;"><img border="0" data-original-height="900" data-original-width="1200" height="480" src="https://1.bp.blogspot.com/-tP3CSNCU-qU/YLQkv3atvNI/AAAAAAAACgc/NjrwTdn5eZoAg2aJKqdumiwV3k61yNYPACNcBGAsYHQ/w640-h480/elekit1.jpg" width="640" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;"><span style="font-family: arial;">Starting off at the professional assembly area a.k.a. dining table.</span></td></tr></tbody></table><br /><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto;"><tbody><tr><td style="text-align: center;"><a href="https://1.bp.blogspot.com/-NMZi1iAWnac/YLQkvxlWQbI/AAAAAAAACgk/8C8_QReyeZY7qRAm5ztB5LzrH2Ko_RJAgCNcBGAsYHQ/s1200/elekit2.jpg" style="margin-left: auto; margin-right: auto;"><img border="0" data-original-height="900" data-original-width="1200" height="480" src="https://1.bp.blogspot.com/-NMZi1iAWnac/YLQkvxlWQbI/AAAAAAAACgk/8C8_QReyeZY7qRAm5ztB5LzrH2Ko_RJAgCNcBGAsYHQ/w640-h480/elekit2.jpg" width="640" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;"><span style="font-family: arial;">The Takmans are too large to fit and the legs have to be bent in a curved fashion to fit the board.</span></td></tr></tbody></table><br /><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto;"><tbody><tr><td style="text-align: center;"><a href="https://1.bp.blogspot.com/-VkNdcBy_WBM/YLQkv3BhhjI/AAAAAAAACgg/CrblAapEKgsZVgh01bWnVAAOejNPS-UwgCNcBGAsYHQ/s1200/elekit3.jpg" style="margin-left: auto; margin-right: auto;"><img border="0" data-original-height="900" data-original-width="1200" height="480" src="https://1.bp.blogspot.com/-VkNdcBy_WBM/YLQkv3BhhjI/AAAAAAAACgg/CrblAapEKgsZVgh01bWnVAAOejNPS-UwgCNcBGAsYHQ/w640-h480/elekit3.jpg" width="640" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;"><span style="font-family: arial;">Soldering of the resistors is complete.</span></td></tr></tbody></table><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-BvXyUhQNPbo/YLQkwqWgLlI/AAAAAAAACgo/ooJcpobMwv8oKHb1NNWdAvxc2EmHkUi9wCNcBGAsYHQ/s1200/elekit4.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="900" data-original-width="1200" height="480" src="https://1.bp.blogspot.com/-BvXyUhQNPbo/YLQkwqWgLlI/AAAAAAAACgo/ooJcpobMwv8oKHb1NNWdAvxc2EmHkUi9wCNcBGAsYHQ/w640-h480/elekit4.jpg" width="640" /></a></div><br /><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto;"><tbody><tr><td style="text-align: center;"><a href="https://1.bp.blogspot.com/-p8e4f7xsFe4/YLQkxBweI9I/AAAAAAAACgs/4gh34Rh2hkwbTXMKZQ5SO0d2ro7hXLRBACNcBGAsYHQ/s1200/elekit5.jpg" style="margin-left: auto; margin-right: auto;"><img border="0" data-original-height="900" data-original-width="1200" height="480" src="https://1.bp.blogspot.com/-p8e4f7xsFe4/YLQkxBweI9I/AAAAAAAACgs/4gh34Rh2hkwbTXMKZQ5SO0d2ro7hXLRBACNcBGAsYHQ/w640-h480/elekit5.jpg" width="640" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;"><span style="font-family: arial;">Plenty of space for upgrading the coupling capacitors.</span></td></tr></tbody></table><br /><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh5oP88XjQVUXCUbXX_meBvQbJ1TZi1-bjTN89UthxltxoCnfEJ8Ui_ViiYL_1bZTBtEQ6NRHeZX79trldn1A9u5o4KSc15Zc_Qju-kxEgWxE6YIsBWQnBYckxVOmBkAuzaFF7jPEkTMFpy/s1200/elekit6.jpg" style="margin-left: auto; margin-right: auto;"><img border="0" data-original-height="900" data-original-width="1200" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh5oP88XjQVUXCUbXX_meBvQbJ1TZi1-bjTN89UthxltxoCnfEJ8Ui_ViiYL_1bZTBtEQ6NRHeZX79trldn1A9u5o4KSc15Zc_Qju-kxEgWxE6YIsBWQnBYckxVOmBkAuzaFF7jPEkTMFpy/w640-h480/elekit6.jpg" width="640" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;"><span style="font-family: arial;">This is the top side of the board.

I happily soldered them to the input pads. They should have been wired to the output pads instead (Elekit refers to them as output pads in the sense that they receive the output from the potentiometer). </span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;">The power and output transformer connect to the PCB via push-on Molex connectors. Since the stars were aligned, I decided to run in both the stock output transformers and the Lundahl ones which are optional. </span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;">One criticism I have is with respect to the sheet metal covers. They have a fair amount of ring, and degrade the sound quality. This was very noticeable when I installed both after my run-in process was completed.</span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;"><b>Sound Quality</b></span></div><div><br /></div><div><span style="font-family: arial;">Paired with Genalex 300B tubes and a variety of 12AX7 and 12AU7 tubes from my stockpile, I gave each set of output transformers about 10 hours of run-time before I did any critical listening. I used my Totaldac DAC (using digital volume control) and icOn4 Pro as preamplifier, and my Vivid Giya G4 speakers. </span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;">The Elekit is highly detailed, fast and open. The tone is light and clear, so if you are seeking the vintage 300B tone (warm, full and midrange-centric) you should look elsewhere.</span><span style="font-family: arial;"> Despite the low power on tap, vocals and smaller works were an absolute treat with the Vivid. While the midrange was not overly liquid, the presentation was clearly in the tube amp camp. </span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;">Soundstaging and imaging was holographic with pinpoint placement and excellent depth and width. The bass control and dynamics were satisfactory, but this is not the reason why you choose a single-ended tube amp. I believe that given the right set of loudspeakers (i.e. high efficiency), the Elekit would have no problem bringing the house down.</span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;">Swapping in the Lundahl transformer is the point where the Elekit is transformed from competent to world-class. The gains in detail retrieval, control over both ends of the frequency spectrum and refinement make the Lundahl a solid investment proposition. Elekit supplies the stock transformer even if you opt for the Lundahl, so you could always upgrade in the future, only losing out on having additional shipping costs.</span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;">The Elekit is good enough to be your end-game amplifier unless you suffer from equipment polygamy (which Audiophile doesn't ?). I was heartened to find such high quality at an affordable price, knowing that many would be able to enjoy its fine musicality. </span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;"><b>Conclusion</b> </span><span style="font-family: arial;"> </span></div><div><span style="font-family: arial;"><div style="font-family: "Times New Roman";"><span style="font-family: arial;"><br /></span></div><div style="font-family: "Times New Roman";"><span style="font-family: arial;">There is a sense of rightness to the Elekit, and there is the invaluable ability to dial it in precisely to your taste through judicious choice of parts. </span></div><div style="font-family: "Times New Roman";"><span style="font-family: arial;"><br /></span></div><div style="font-family: "Times New Roman";"><span style="font-family: arial;">It comes in at an attractive price tag, so the only real downside is that you need to spend the time and effort to build it yourself.

Sound quality is typically poor or mediocre. Integrated audio chips work in noisy electrical environments, and usually lack the necessary power to drive high-quality headphones. </span></p><p><span style="font-family: arial;">Astell&Kern have released a USB-C DAC / headphone amp that provides an instant boost to your sound quality and lets you use your 3.5mm wired equipment with devices that lack a headphone jack, like some of the new mobile phones.</span></p><p><span style="font-family: arial;"><b>Description</b></span></p><div style="text-align: left;"><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj2iMLNe_oByw2iGuZXX_LaHDFPmntFcVjvb75DMdRWyghlFJV-qe4Gx2EbojMZjIcmxNGEHLdUCj9WcI-T8Qv87fMYIwgj5VBCtc3X5__JRaq02t68PlX61UKDW3lSNIVuF1nPj6cQC_Jt/s1200/ak1.JPG" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="800" data-original-width="1200" height="426" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj2iMLNe_oByw2iGuZXX_LaHDFPmntFcVjvb75DMdRWyghlFJV-qe4Gx2EbojMZjIcmxNGEHLdUCj9WcI-T8Qv87fMYIwgj5VBCtc3X5__JRaq02t68PlX61UKDW3lSNIVuF1nPj6cQC_Jt/w640-h426/ak1.JPG" width="640" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><br /></div></div><div style="text-align: left;"><span style="font-family: arial;">The USB-C Dual DAC Cable ("Dual DAC") is based on twin Cirrus Logic CS43198 MasterHIFI Digital-to-Analog Converters. The CS43198 is a Delta-Sigma oversampling DAC that supports up to 384 kHz sampling rate / 32-bit resolution for PCM and DSD 256. </span></div><div style="text-align: left;"><span style="font-family: arial;"><br /></span></div><div style="text-align: left;"><span style="font-family: arial;">As expected from an Astell&Kern product, the Dual DAC is finished to a high standard. The compact metal Zinc alloy body (it is no bigger than a thumb-drive at 50 mm x 17 mm x 10.3mm !) houses an integrated circuit with bespoke designed capacitors and an optimised audio circuit to minimise power fluctuations and provide premium sound quality. </span></div><div style="text-align: left;"><span style="font-family: arial;"><br /></span></div><div style="text-align: left;"><span style="font-family: arial;">Astell&Kern claims that the analog amplifier is powerful enough to drive a variety of high impedance headphones with a 2V rms output level (condition no load). Output impedance is suitably low at 2 ohms, which should ensure lower distortion into low impedance headphones. </span></div><div style="text-align: left;"><span style="font-family: arial;"><br /></span></div><div style="text-align: left;"><span style="font-family: arial;">The fixed cable is a durable 4-core cable made out of a core of Technora aramid fiber, with a layer of thick silver-plated copper wrapped around it, followed by a further layer of copper wire in a spiral arrangement. The tastefully angled housing is carried over to the matching USB-C connector. A single LED indicates operation, while volume is controlled through the device it is paired with. </span></div><div style="text-align: left;"><span style="font-family: arial;"><br /></span></div><div style="text-align: left;"><div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-twxmMJbUF90/YHZu1Sj3p_I/AAAAAAAACfo/IylRy0XIlxwzl4xm5SBVR4hYh3QrNQo_QCNcBGAsYHQ/s1200/ak2.JPG" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="800" data-original-width="1200" height="426" src="https://1.bp.blogspot.com/-twxmMJbUF90/YHZu1Sj3p_I/AAAAAAAACfo/IylRy0XIlxwzl4xm5SBVR4hYh3QrNQo_QCNcBGAsYHQ/w640-h426/ak2.JPG" width="640" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj32Qfc_b5v9pEd0xMqVNc6JsOhiVTTY9D3Ro21OsTgJL8OAIwxIOAozFry138XGCQ2XvyD0oDkiY9OYT_UdF4ng3jOiIOg2ktksoZBjM03A_YEZwTapvQFM41kRPacxd8xwf84suTMGgTz/s1200/ak3.JPG" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="800" data-original-width="1200" height="426" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj32Qfc_b5v9pEd0xMqVNc6JsOhiVTTY9D3Ro21OsTgJL8OAIwxIOAozFry138XGCQ2XvyD0oDkiY9OYT_UdF4ng3jOiIOg2ktksoZBjM03A_YEZwTapvQFM41kRPacxd8xwf84suTMGgTz/w640-h426/ak3.JPG" width="640" /></a></div><span style="font-family: arial;"><br /></span></div><div style="text-align: left;"><span style="font-family: arial;"><br /></span></div><div style="text-align: left;"><span style="font-family: arial;"><b>Operation</b></span></div><div style="text-align: left;"><span style="font-family: arial;"><b><br /></b></span></div><div style="text-align: left;"><span style="font-family: arial;">The Dual DAC worked without any issue with a variety of devices I tried - a Samsung Galaxy S10+ mobile phone, a Windows 10 notebook, and a 2020 Macbook Pro notebook. The bulk of my listening was done on the Samsung, playing music either through the Tidal or USB Audio Player Pro app. Power-draw was modest and I did not notice any adverse impact on battery life. Sadly, the Dual DAC is incompatible with iOS devices due to current limitations through their ports. Both high-resolution PCM and DSD files played without any issue.</span></div><div style="text-align: left;"><span style="font-family: arial;"><br /></span></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgIPGZXZeKxbx_CMyAQf9L2GSRaDrCMi0w9ID5FAIaOdAxIZ9wCzkqFyYtdi3rhQ3AA1DK3IpkB_BN2Ee-upc85_pkyZ9hau3xC34Xzgb12puguySpTaX2OCfBSJI6-Tl-bef0qN3SZKr5F/s2577/ak+dsd.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="2577" data-original-width="1221" height="640" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgIPGZXZeKxbx_CMyAQf9L2GSRaDrCMi0w9ID5FAIaOdAxIZ9wCzkqFyYtdi3rhQ3AA1DK3IpkB_BN2Ee-upc85_pkyZ9hau3xC34Xzgb12puguySpTaX2OCfBSJI6-Tl-bef0qN3SZKr5F/w304-h640/ak+dsd.jpg" width="304" /></a></div><br /><div style="text-align: left;"><br /></div><div style="text-align: left;"><span style="font-family: arial;">The USB-C connector is quite large and may not fit properly through your mobile phone case. My case cut-outs were not big enough and I had to remove my phone case to plug in the Dual DAC. I am in two minds about the fixed lead. I like the idea of a fixed cable, but it is quite short and in the case of my Windows 10 notebook, the USB ports are located on the side of the screen, which left the Dual DAC suspended in the air.</span></div><div style="text-align: left;"><br /></div><div style="text-align: left;"><span style="font-family: arial;"><b>Sound Quality</b></span></div><div style="text-align: left;"><span style="font-family: arial;"><br /></span></div><div style="text-align: left;"><span style="font-family: arial;">The Dual DAC provided a significant uplift in sound quality and drive capability, with the improvements most noticeable on difficult to drive headphones. I tried it with a variety of IEMs, as well as two headphones - a Beyer DT880 (250 ohm version) and an E-MU Teak. Most of my listening was done on the E-MU for reasons explained below.</span></div><div style="text-align: left;"><span style="font-family: arial;"><br /></span></div><div style="text-align: left;"><span style="font-family: arial;">The most striking improvement was in the reproduction of low-frequencies. The Dual DAC added a tight punchiness that went deep. Vocals gained clarity and refinement, adding sweetness and uncovering details that were previously obscured. High-frequencies too gained extension and airiness, giving music a brighter and more illuminated tone. The soundstage opened up, with an increase in dimensionality, and the sense of acoustic space in the recording.</span></div><div style="text-align: left;"><span style="font-family: arial;"><br /></span></div><div style="text-align: left;"><span style="font-family: arial;">Pairing the Dual DAC with IEMs brought improvements in sound quality, but the Dual DAC's strength was in bringing extra current and voltage drive for more difficult to drive headphones (within reason). While the DT880 showed improvements with the Dual DAC, it lacked the dynamic freedom and ease compared to my desktop headphone amps. The E-MU Teak is easier to drive in comparison and was very comfortable with the Dual DAC, even at high levels. Given the compact size of the Dual DAC, this is a reasonable compromise.</span></div><div style="text-align: left;"><span style="font-family: arial;"><br /></span></div><div style="text-align: left;"><span style="font-family: arial;">I was impressed with the high level of sound quality delivered by the Dual DAC and can highly recommend it to Android phone users who want the best sound quality on the go, or to business travelers that need a high-quality and portable audio rig.</span></div><div style="text-align: left;"><span style="font-family: arial;"><br /></span></div><div style="text-align: left;"><span style="font-family: arial;"><b>Conclusion</b> </span></div><div style="text-align: left;"><span style="font-family: arial;"><br /></span></div><div style="text-align: left;"><span style="font-family: arial;">From a pricing standpoint, the Dual DAC is a premium product that carries a corresponding price tag.

According to Acrolink, the PC9900 is an upgraded version of the PC9700 and features new special shielding technology. </span></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-MMMJS-dHK6U/X6ZuB6rU8EI/AAAAAAAACc0/Ocbx45lbriINHwBcc_FxWwp7xRe0Co6lgCNcBGAsYHQ/s1200/mexcel%2B1.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="800" data-original-width="1200" height="426" src="https://1.bp.blogspot.com/-MMMJS-dHK6U/X6ZuB6rU8EI/AAAAAAAACc0/Ocbx45lbriINHwBcc_FxWwp7xRe0Co6lgCNcBGAsYHQ/w640-h426/mexcel%2B1.JPG" width="640" /></a></div><br /><p></p><p><span style="font-family: arial;"><b>Description</b></span></p><p><span style="font-family: arial;">Visually and reading off the specifications sheet, the PC9900 and PC9700 are near identical twins. The Live and Neutral conductors are the same D.U.C.C. Stressfree 7N wires consisting of 50 strands of 0.32 mm diameter conductors, while the ground is similar except the wires are made from super-anneal 4.5N copper. </span></p><p><span style="font-family: arial;">The shield is described as polyurethane enameled 4N copper braid with special shielding technology - carbon fabric sleeves. In comparison, the PC9700 uses the same copper braid combined with semi-conductive carbon tape. </span></p><p><span style="font-family: arial;">Otherwise the PC9900 looks and feels the same, with a diameter of 16 mm and identical resistance and capacitance values. </span></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhkhM6p-I1NdN4Gy00sI8GUBLuiJrT2z0CjBURf7h9HKlEKdFEGb92leg6gjD6AymuW932xUaDbGEdUlAbobUDMJoI4a0cd3WdLUrWmwSFTFHSyRZBWGOCXupmCf8GiFmBLEhUqKNIXOZmw/s1200/mexcel+2.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="800" data-original-width="1200" height="426" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhkhM6p-I1NdN4Gy00sI8GUBLuiJrT2z0CjBURf7h9HKlEKdFEGb92leg6gjD6AymuW932xUaDbGEdUlAbobUDMJoI4a0cd3WdLUrWmwSFTFHSyRZBWGOCXupmCf8GiFmBLEhUqKNIXOZmw/w640-h426/mexcel+2.JPG" width="640" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-KVoOTnjIt1Y/X6ZuOL-mc3I/AAAAAAAACdA/J4NM4sY5magIp7pXD5lisxcVcstEl0h3ACNcBGAsYHQ/s2048/mexcel%2Bplug2.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1365" data-original-width="2048" height="426" src="https://1.bp.blogspot.com/-KVoOTnjIt1Y/X6ZuOL-mc3I/AAAAAAAACdA/J4NM4sY5magIp7pXD5lisxcVcstEl0h3ACNcBGAsYHQ/w640-h426/mexcel%2Bplug2.JPG" width="640" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgvUuIcTX9-aW4RdOhrAKcgRJffbsD-7C3S58b0HvTPYz-EE0UH9yXETuq6v-Volnetf5eM1rBuH1uqNKUQlzLXrbyXV0_YrE0BhiJG3bfu-tMz3kr-G6_00_W1_GMBIRewlQuUoglt6GTJ/s1200/mexcel+plug.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="800" data-original-width="1200" height="426" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgvUuIcTX9-aW4RdOhrAKcgRJffbsD-7C3S58b0HvTPYz-EE0UH9yXETuq6v-Volnetf5eM1rBuH1uqNKUQlzLXrbyXV0_YrE0BhiJG3bfu-tMz3kr-G6_00_W1_GMBIRewlQuUoglt6GTJ/w640-h426/mexcel+plug.JPG" width="640" /></a></div><span style="font-family: arial;"><p><span style="font-family: arial;"><br /></span></p>I no longer had the PC9700 on hand so I could not compare the two models. Instead, I used the 8N-PC8100 as a baseline for comparison instead.</span><p></p><p><span style="font-family: arial;"><b>Sound Quality</b></span></p><p><span style="font-family: arial;">Acrolink Mexcel users expect the finest levels of resolving power and suppressed noise floor, which the PC9900 delivers in spades. </span></p><p><span style="font-family: arial;">The PC9900 has extremely high levels of resolution across the frequency range, with tight and powerful bass lines, and high frequencies that are extended and clean. In typical Mexcel fashion, this is delivered in very quick and focused transients, with a natural decay. </span><span style="font-family: arial;">Due to the very low noise floor, the PC9900 is almost like delivering a jolt to your system, giving it a sudden boost in contrast and dynamic range. </span></p><p><span style="font-family: arial;">Tonally, the PC9900 sounds similar to the PC9700 (based on memory). A quick read of my previous review of the <a href="https://singaporehifi.blogspot.com/2017/09/acrolink-mexcel-7n-pc-6700-and-7n.html">PC9700</a> provides more insight into the character of both the PC9700 and PC9900. However, the PC9900 offers subtly improved resolving power with a little bit more focus and drive. I noticed that the Mexcel twins differ in how the human voice is presented. While both cables have more sweetness in the midrange compared to other Mexcel models, the PC9900 has a silkier and more fluid delivery. However, this comes at the expense of some snap and presence.</span></p><p><span style="font-family: arial;">Comparisons to the PC8100 proved interesting. Unlike the PC9700, I would consider both the PC8100 and PC9900 to be on par with each other. The PC9900 is like using a computer monitor with higher resolution. The PC8100 makes do with lower resolution, but with more colour contrast, and a slightly warmer hue. Your choice of poison boils down more to taste. If you like a bolder presentation with more meat and flavour, the PC8100 fits the bill. The PC9900 is perfect for the palate that favours microdetail and a more refined and sophisticated presentation. If you like your Japanese whisky, think of the PC8100 as Nikka, and PC9900 as Yamazaki.</span></p><p><span style="font-family: arial;"><b>Conclusion</b></span></p><p><span style="font-family: arial;">Acrolink Mexcel power cords are one of the finest products in the industry and come with a strong personal recommendation. While they are expensive, the level of performance delivered is very reasonable. I would have hesitated to say this some years ago, but a quick look at audio magazines and websites shows that flagship cables from the competition can even cost multiples of the PC9900 - <b>Highly Recommended.</b></span></p><p><span style="font-family: arial;">A big thanks goes out to X-Audio for arranging for the review sample.</span></p><div style="text-align: left;"><span style="font-family: arial;"><b><span style="font-size: x-small;"><br /></span></b></span></div><div style="text-align: left;"><span style="font-family: arial;"><b><span style="font-size: x-small;">Acrolink Mexcel 7N-PC9900 Power Cord<br /></span></b></span><span style="font-family: arial;"><span style="font-size: x-small;">Price : S$ 5,500</span></span></div><p><br /></p><div style="text-align: left;"><b style="font-family: arial; font-size: small;">X-Audio<br /></b><span style="font-family: arial; font-size: small;">1 Jalan Anak Bukit <br /></span><span style="font-family: arial; font-size: small;">#01-01S, Bukit Timah Plaza<br /></span><span style="font-family: arial;"><span style="font-size: x-small;">Tel : 64662642<br /></span></span><span style="font-family: arial;"> </span></div><p><span style="font-family: arial;"><br /></span></p><p><span style="font-family: arial;"> </span></p><p><span style="font-family: arial;"> </span></p>Eric Tehhttp://www.blogger.com/profile/05157135145227727200noreply@blogger.com0tag:blogger.com,1999:blog-684396141123606281.post-48989970297587201182020-09-18T03:37:00.009-07:002020-10-29T19:43:43.253-07:00AGD Audion Monoblock Power Amplifier<p><span style="font-family: arial;"><b>Introduction</b></span></p><p><span style="font-family: arial;">AGD Productions Inc is the new kid on the high-end audio block.

You can opt for the brushed finish, or a chrome finish for a premium. My review sample came with the brushed finish. The company logo is engraved into the front panel, while all inputs and the power inlet are located at the rear. The excellent speaker binding posts (a pair of WBT Nexgen 5-way posts) are located on the top of the amplifier, behind the GaNTube</span><span style="font-family: arial;">™</span><span style="font-family: arial;">. If you are using spade terminated speaker cables, this all fits very nicely. However, if you are using banana plug terminations like me, your cables will arch gracefully (like my flexible speaker cables), or suspend your Audion amplifier in mid-air in a worst-case scenario.</span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;">The power switch is located directly above the IEC inlet and will be partially blocked by monstrous power plugs that ship with any serious garden hose. </span><span style="font-family: arial;">Otherwise operation is event-free. The GaNTube</span><span style="font-family: arial;">™</span><span style="font-family: arial;"> glows orange like a vacuum tube except very little heat is produced. I demonstrated this to a visiting audiophile by resting my finger on the GaNTube</span><span style="font-family: arial;">™</span><span style="font-family: arial;"> in the middle of a listening session. No start-up noises or power-down thumps - excellent manners for this house guest. </span></div><div><span style="font-family: arial;"><br /></span></div><div><div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-4Ft7IAm2V1Q/X5gbnR0wsII/AAAAAAAACcc/HCKIdRzIqLIuZkB5N_auCT2paqhSX6LVQCNcBGAsYHQ/s1200/audion%2Bfront%2B2.JPG" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1200" data-original-width="800" height="640" src="https://1.bp.blogspot.com/-4Ft7IAm2V1Q/X5gbnR0wsII/AAAAAAAACcc/HCKIdRzIqLIuZkB5N_auCT2paqhSX6LVQCNcBGAsYHQ/w426-h640/audion%2Bfront%2B2.JPG" width="426" /></a></div><br /></div><div><span style="font-family: arial;">The Audion packs plenty of power, delivering 85 WPC into 8 ohms and 170 WPC into 4 ohms. It can deliver more than 30A of current which should be more than enough for most of the speakers out there in the wild. The input impedance of both the RCA and XLR input is 40 kohms (600 ohm inputs can be custom ordered). Noise is an astonishingly low -130db. The GaNTube</span><span style="font-family: arial;">™ switches at a frequency of 400 kHz.</span></div><div><span style="font-family: arial;"> </span></div><div><span style="font-family: arial;">I tried the Audion with three DACs with digital volume control (the Chord Dave, Totaldac D-1 Six and Antelope Audio Zodiac Platinum DAC). I also tried using a Music First Audio TVC preamp. Although the specifications do not specify the input sensitivity / gain of the Audion, it is definitely quite high. All three DACs were being used between -30db to -20db. In the case of a DAC with digital volume control, that is sufficient attenuation to potentially result in resolution loss. If you are using an active preamp with high amounts of gain, you have been warned ! In fact, this is one of the very few power amplifiers I've used that sound really good driven directly from the source. Save your pennies by skipping the preamp ! Another noteworthy point is that Audion sounds good through both the RCA and XLR input - no worries if your source is single-ended only.</span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;"><b>Sound Quality</b></span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;">Let's get this out of the way first - Class D amplifiers get a bad rap from audiophiles. Conventional wisdom is that Class D amplifiers are sterile and lifeless. I have owned and auditioned enough Class D amplifiers to understand their appeal and their strengths. Many years ago, I bought a pair of monoblock amplifiers from a Japanese company called Flying Mole. They are no longer in business, but the product showed great promise. I have also owned a number of Class T amps (i.e. based on the Tripath chip), and amplifiers with both B&O ICEPower and Hypex modules. Each generation of module showed steady improvement, and a number were of high enough quality to challenge traditional amplifier designs.</span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;">The Audion need not make any excuses for itself. The sound quality easily surpasses most traditional amplifier designs and can even be considered as a serious challenger to the top amplifiers on the market. </span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;">First up is the bass authority you get from the Audion. Class D amplifiers typically have superb control over your woofers. In some cases, you get a tight bottom-end that seems artificial with a lack of shading or texture. The Audion breathes freely here - as an example, double bass notes flow with timbre and life. The bass has just the right amount of wetness for me, although I did feel that there was a slight midbass emphasis, which resulted in a weightier and warmer tone.</span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;">The midrange has an inner glow quality that good single-ended triode amplifiers possess. However, this glow is even-handed and avoids the thick luscious tone that some tube amplifiers aim for. Some equipment smooth over the midrange to portray a more "musical" tone, but the Audion retains plenty of microdetail. </span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;">The Audion's high-frequency performance must have delivered the greatest surprise during my review experience. Even the best class D modules I have heard (with the exception of the Orchard Audio BOSC - a story for another day) subtly reduce the top-end air in the recordings. While they do not by any means sound dull or rolled-off, you could sense a slight reduction in the scale of acoustic space. I always assumed that this was a necessary evil resulting from the low-pass filter required in class D designs to filter out ultrasonic noise. The Audion come through clear and extended. Neither is there any glare or harshness in the reproduction - cymbals crash and bells ring in a clear and extended manner, with a firm but crisp tone. </span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;">Solid state amplifiers excel in staging precision but often cannot match tube amplifiers in dimensionality - the acoustic space around voices and instruments, and the perception of depth and height. The Audion could very well have been of vacuum tube pedigree in this regard, delivering convincing reproductions of each voice and instrument in the recording mix. Marry this with solid state speed and low frequency control, compactness and lack of heat - you truly get the best of both worlds here ! </span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;">Prior to my experience with the Audion, discussions about Class D amplifiers with friends have always been caveated to a degree, e.g. "They deliver a lot of clean power for the price and are very accurate, but you really need a good preamplifier to flesh out the tone and complete the picture.", or "They really deliver bang for the buck, but if you spend a lot more, you can get even higher sonic performance." </span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;">My caveats here are altogether different. Firstly, the high amounts of gain requires some care in matching with preamplifiers and sources. Secondly, the Audion is not affordable although it delivers exceptional sound quality for the price. The price tag puts it out of reach of most audiophiles but quality is never cheap. </span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;">You could also make the argument that the Audion is not neutral. It isn't and to me it was almost certainly a deliberate design choice. Instead, it chose to be musical and delicate, while having the speed, power and control to bring realism to large-scale works. You can now have your cake and eat it ! </span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;"><b>Conclusion</b></span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;">The Audion is a truly revolutionary product. I understand that AGD already has several different </span><span style="font-family: arial;">GaNTube™ designs in the making, including a higher powered version, and a lower powered one for headamp use. The new modules may be installed in place of the current </span><span style="font-family: arial;">GaNTube™, which shows that the socketed </span><span style="font-family: arial;">GaNTube™ is not merely a whimsical fashion choice. </span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;">Keep you eye on AGD, this is a truly special product that will redefine your notions of Class D and solid state technology - <b>Highly Recommended.</b></span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;">This review was made possible with the kind assistance of Horizon Acoustics, sole distributor of AGD Productions Inc in Singapore. </span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;"><b>AGD Audion Monoblock Power Amplifier</b></span></div><div><span style="font-family: arial;">Price : SGD 12,800</span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;"><br /></span></div><div><span style="font-family: arial;"><b><span style="font-size: x-small;">Horizon Acoustics</span></b></span></div><div><span style="font-family: arial;"><span style="font-size: x-small;"><br /></span></span></div><div><span style="font-family: arial;"><span style="font-size: x-small;">1 Pemimpin Drive</span></span></div><div><span style="font-family: arial;"><span style="font-size: x-small;">#08-11, One Pemipin</span></span></div><div><span style="font-family: arial;"><span style="font-size: x-small;">Singapore 576151</span></span></div><div><span style="font-family: arial;"><span style="font-size: x-small;">http://www.horizonacoustics.com</span></span></div><div><br /></div>Eric Tehhttp://www.blogger.com/profile/05157135145227727200noreply@blogger.com0
