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.
