I've owned an SLP-98 twice now, usually used with tube amps. The only SS amp I remember specifically was the Cary CAA-1 class D (which I happen to have listed). It was quite detailed, mids more forward than what I was used to, great bass, but did not sound as natural to me as my EL34 amp. I needed to have a cool running amp for a while, which is why I bought it. The Cary mated fairly well with the Cary, but alas not my cup of tea. I'd recommend sticking with tubes if can. I was considering a class A SS amp, but when I put the tube amp back in the system I decided to stay with tubes. BTW, price range and what speakers it would be driving would help narrow down the choices.
