AVA FET 600

I've heard it, a great amp. I thought very good bass tone and harmonics in particular.
I own a Synergy 450 which Frank is quoted as saying is a toss up with FET 600.
450 much better than Odyssey, McCormack, Belles, I had before it.
Call AVA, last time I was there about a year ago he was running a pr of Salk and one of B&W , I think they were 802.

I had the FET 600 driving my B&W 802’s until I did a major system upgrade. It was a great match. Had been using ARC tubes before but felt AVA much better synergy. The speaker connectors are, however, very ackward. Beyond that great amp.
