I heard the Synthesis A100T that @audiotroy mentions and it’s a fantastic amp. I’ve owned and heard a lot of gear over the years yet can’t recall another component that impressed me as much.
There’s also its smaller stablemate with 40 watts that sounds almost as good.
I should also mention that I heard both amps at Deja Vu in Vienna VA on Monday this week. I had an incredible experience there courtesy of owner Vu, who spent a great deal of time showing me around their impressive facility.
Anyway, I don’t want to step on Audiotroy’s toes by mentioning another Synthesis dealer but feel it’s only fair to give a shout out to Deja Vu since that’s where I heard the amps.
Had $8k (or even $6.5k for the 40w) been in my budget I wouldn’t have hesitated.
Good luck with your search!
