Icon Audio PS1 MkII Phono Pre-Amplifier

Icon Audio amplifier have an enviable reputation following reviews. First introduced in 2005, the PS1 has proved to be one of Icon Audio's best selling phono pre-amplifiers. It is well known that for many reason, valves can sound much better than transistors, this is especially so with vinyl reproduction. This is because:

- The massve overload of valves prevents distortion on highly modulated or scratched/worn LPs, therefore minimising noise.

- The warm sound of valves is particularly suited to the reproduction of analogue music from vinyl.

- The huge 40dB RIAA difference between 20Hz and 20kHz is easier for valves than transistors.

- Icon Audio use hard wired point-to-point wiring with no printed circuit board.
