I happened to drop by Audio Basic Singapore (local dealer for Telos) recently. Another customer walked in and Steven Cheah, manager and principal of Audio Basic asked him to listen to a demonstration of the Telos Quantum Noise Resonator ("QNR").
The QNR is a compact device about the size of a paperback novel. It is quite heavy, being made out of machined aircraft grade aluminum. The chassis has no visible screws, and a top cover acrylic window allows the user to see the circuit board, and a LED display that blinks meaningfully when the QNR is in operation.
The QNR is an AC mains conditioner and works by means of production of eight different frequencies, which are namely, 120 Hz, 60 Hz, 30 Hz, 15 Hz, 7.5 Hz, 3.75 Hz, 1.875 Hz and 0.9375 Hz. Telos claims that the QNR is able to correct distortions in the AC waveform, and converts noise above 1 kHz into light.
As the QNR is connected in parallel with your equipment, there is no current limitation unlike series type of line conditioners.
The QNR is equipped with an IEC socket on its rear panel, which allows experimentation with different power cords.
I happened to stay long enough to listen to a demonstation to two different customers. In both cases, hooking up the QNR resulted in an increase in spaciousness of the sound, and improvement in three dimensionality of the soundstage. Separation and focus was better too. I also felt that with the QNR,
the leading edge of musical instruments was bolder and more energetic, with an improvement in decay too.
The effect is quite obvious, and I may be borrowing a unit for home evaluation. Stay tuned.
