Icon Audio PS1 MK II Pure Valve Phono Pre Amplifier
Introduced in 2005 the PS1 has proved to be one of Icon's best sellers. This model has had many excellent reviews in the worlds Hi Fi press.
New for 2013 are new cosmetics, and improved power supply and the compatibility with our new MC transformers.
It is well know that valves can sound much better than transistors, this is especially so with LP reproduction. Mainly because:
The massive overload of valves prevents distortion on highly modulated or worn LPs therefore reducing noise.
The “warm” sound of valves is well suited to the reproduction of analogue music from LP.
The huge 40db RIAA difference between 20 Hz and 20 kHz is easier for valves than transistors.
Our “passive” design uses no “feedback”
Our simple design uses “hi fi” components.
We use “hand wired” “point to point” wiring with no printed circuit board.It is essential that that these precious few microvolts of signal from the pickup cartridge go straight in to the valve without any switches or coupling capacitor in the way to add sonic impurities.
The PS1 story from David Shaw Icons founder:
“I designed the PS1 for maximum musical detail, but without exaggerating the imperfections through wear or older records. Valves are much more tolerant to overload and distortion, they recover quicker and distort less than transistors. Therefore valves will deal with the huge transient spikes present in imperfect LPs better than transistors. This gives a much more pleasing sound”.
