No 1622 - PREAMPLIFIER
The pre amplifier is the hub in an audio system; the device that all sources and the power amplifier are connected to. Furthermore, it is the interface to the user. Great attention to details have been paid during the design process of the Sybarite Audio No 1622 – from the precision machined faceplate to the volume/gain control, based on an optical, industrial grade rotary encoder. The infrared remote control is not left to chance, but machined from aluminum alloy by our partner in Germany.​
​​​​
The Sybarite Audio No 1622 is a cost-no-object all discrete solid state design operating in class A, employing a relay based R-2R-ladder gain control. As transparency and accuracy are words of honor for us; the main design objectives have been: ultralow noise and distortion, wide bandwidth, large overload margin, accurate RIAA-tracking in the phonograph section among many other aspects of performance.
