Have ventured into SET with Jota mono's. 90% Analog. The Vinyl One has a volume pot with 70db gain and no noise. Power cords have really helped. ErnieM's on my integrated subwoofers opened things up.
Looks to me like a beautiful system. Could easily (as you insinuated) be used with any tube amp, although I’d imagine you would consider a SET 300B, 2A3, or 45. Unless I missed something, how many watts are you currently using?
