Icon Audio PS3 MkII Phono Pre-Amplifier

Following on from Icon Audio's acclaimed PS1 phono stage which won “5 Globes” in Hi Fi World (03/2008) for its excellent sound quality, they have pushed the boundaries of valve technology even further with the new PS3 model. To do this they have used all their expertise and experience to create a “no expense spared” phono stage which addresses all the weaknesses of more conventional designs but still retaining our “All Valve” philosophy. And amazing value!

Special amplification needs a special power supply. Icon Audio started with a large, oversized power transformer and a full wave valve EZ80 rectifier followed by two large chokes for ultra-smooth power. This is then regulated by a low resistance 5687 valve controlled by an ECC83 for the very accurate voltage necessary for exceptional purity and performance. The pre-amp unit uses the “cascode effect” of using two valves together in a special way to obtain high gain with low noise this gives exceptional definition and sound staging whilst keeping the vivid colour and warmth that the PS1 phono stage is famous for. With two inputs and a moving coil option using Icon Audio's own “hand wound” moving coil transformers. The output is handled by the venerable 6SN7. Introduced in 1941, probably the most luxurious sounding hi fi valve ever, with so many old and new version.

Very Impressive Phono Preamplifier at Moderate Price
17 July 2020  | 

This phono preamplifier sounds transparent, dynamic but not too clinical. Music as simply flows out naturally and effortlessly, and is especially good at vocal and classical music reproduction. These sonic characters are probably attributed to its valve regulated and valve stabilised power supply.
I would like to say many thanks to Gary for good communication, secure packing and fast delivery.

Magical Sound phono stage
01 September 2018  | 

This phono preamp was recommended by Gary and thanks to Gary for true recommendation. I upgraded from solid state to tube state.
I would say, at first look, it looked costly for me but when i felt its performance, its beyond price.
Very crystal clear highs without being harsh, Amazing instrumental separation...I found this most recommended phono stage.
And thanks to Gary for good packing and very quick service.
