Reagarding SQ….well, what I consider a ‘Belles’ sound. Very similar to my old 400A, but better at almost everything. The overall sound is what I would call ‘liquid’, and not a hint of anything being etched, grainy, hard, or cold. The gentleman I purchased them from has had almost all David’s Power Module amps, and as opposed to the 150A, 350A, etc. he feels the MB200’s are more tube-like. The others he knew were solid state. I can only take his word for that, but the ‘liquidity’ of the overall presentation is noticeable the first time I heard them. That said, it isn’t ‘mushy’ at all, but rather very refined, somewhat airy but full at the same time, reproduces a very nice big stage, good imaging, detail, much faster than the old 400A, etc. And with 64 amps of peak current they have a lot of grunt, power, and control.
When I had the B&K 3030 in, I had to reduce the loading on my Hagerman to 470 ohms, as it bothered me at 1,000 being too etched on the highs, where I had it with the 400. Well, one of the first things I did was set loading back to 1,000 with the MB’s, and all is good again, nice clean smooth crisp highs again (the Soundsmith MIMC likes 800-1,000 IMO).
Anyway, initial thoughts.
