I also made the switch to SET 2 years ago and came back to my current, more conventional, set up with the AH dac, pre and Belles Ref 350 amp. They drive a pair of Dali Grand full range speakers (90db effecient).
I liked my SET system which consisted of George Wright 2a3 amps, Cain & Cain IM Ben speakers, matching subs, George Wright preamp and a Audio Aero tubed CD player. In the end I missed the scale and impact of a "full range" system. Sure, this system could play very loud and had good dynamics, but in the end it was not as flexible it terms of playing all kinds of music well. Loved the intimacy of SET, but found I could have it with my current system and enjoy improved dymanics and scale on other music.
I only say AH should consider an SS amp as I think (?) the SET lover is a far smaller group and potential market. I have also found one can get most of that SET sound with a carefully matched and thought out dynamic system. I know some SET systems can be dynamic and have a good degree of impact and scale, but I think we can agree they are still a step behind the best "conventional" systems in this regard.
