I listened to the Gamut room and was most impressed. There have been criticisms in the various show reports, particularly , of the first day, but I thought they were great. That means the whole package, including the electronics. The sound was powerful and authorative, detailed and neutral, but lacking the SS amp edge and harshness, which drove me to tubes.
The Gamut amps and CD players have a good reputation of course. I do'nt know enough about alternatives, to suggest one. Except, I did read a review, I think on 6moons, saying the Accuphase amps were a bit more musical, tube like, than Gamut. For me then, that would push me to Accuphase or Luxman, which I personally would buy, if I was not sold on SET's
