SET 45 Amp Driving Dynamic Speakers

Larryi,
I'll stray off topic one last time 😊.  One of the very best sounding SS amplifiers I've heard are the Concert Fidelity ZL 120 and their ZL 200. This little known Japanese products sound absolutely fabulous.  They're hardly ever written or talked about, too bad. 
Charles, 

Larry,
Thank you. Never heard of Vinni Rossi. Zanden is very high end.
Charles, 
Concert Fidelity, are they more to your taste or mine as you see it? Or both?

Hello Inna,
I can’t honestly say that I know your musical/listening taste, rather I recognize that you prefer amplifiers of a certain power range. My taste is unambiguously towards the natural/organic sound with tactile realism.
The Concert Fidelity  SS amplifiers do that exceptionally well. I’ve only heard them with their sibling tube Line Stage which only further helps I’m sure. It’s a pure and natural sound character rather than electronic (the bane of many SS amplifiers IMO).
Charles,

I am using a Yamamoto A08S SET 45 with EML mesh tubes, driving a pair of Zu Audio Druids in a dedicated listening room about 15'x18' and the result is just stunning.
The transparency, detail, tempo, balance and realism is far beyond anything I've ever owned before, or even heard with other people's systems, some costing 10x and more. The cost of my amp + speakers (new) is less than $9K. I couldn't be happier with this setup.
True, it doesn't play nearly as loud as my living room 60lbs, 700 Watt Classe SS amplifier, and I don't expect it to.
When I want to turn the volume up and listen to hard rock, metal or electronic music at live concert levels, I do it in my living room with a system that excels at that :-)
Maybe one can have both worlds. I haven't found that setup yet, but I can only guess is that if it does exist, it will probably cost 20x more than both my systems together.

Ami, that's one of the things that I said - two very different systems.
Charles, of course I like what you do as well. But that's not all. Even flamenco music requires speed an drive let alone Mahavishnu Orchestra's jazz fusion. Bass is important too. Not exaggerated, but just as it was recorded.
It does appear that I strongly gravitate to Lamm/Atma-Sphere camp. Never heard VAC or Allnic let alone Ypsilon and Absolare.
