Van Alstine Synergy amps: Are they quality sound?


I ran a similar thread about a year ago, and got no feedback. I am simply curious why Van Alstine products don't receive more reviews and evaluation. Need some feedback about the sound quality and reliability of VA's "Synergy" amps and one integrated amp.

I owned the FET 600 and his latest FET tube preamp for about 6 months and enjoyed it a lot. Only reason I sold was that I made a major system wide upgrade.

I have had a Synergy 450 for 2 years, first time in 40 years I haven't been looking for a different amp.
Sounds like a high-quality 100 watt tube amp using NOS output tubes better than any currently available.
Easily betters the Hafler, Odyssey, Belles, McCormack and Quad amps I used before.
