I have a 350 and love it. I formerly owned an AVR300 and before that was a "Linnie" with Kairn preamp and aktiv Kabers w/3 amps. The improvement of the 350 over the 300, at $500, is the best investment in audio, IMO. The noise floor drops to nothing, rendering all instrumentation lifelike in body and spaciousness, and voice emotional quality will make you cry. When I was an audio dealer, from 1976-1998, that kind of improvement used to cost thousands, or even be unobtainable. The rest of my system is two pairs of AE1 MkIII with a REL Britannia 2 sub, and Arcam FMJ DV29 as transport (using the AVR350 DAC), Nordost cabling.
