Best Sounding Solid State Amp?

For the money, I recommend Clayton amps. They have the bass control of solid state and a very tubey midrange. Check out the reviews. One mentioned the Clayton was the best sounding amp under $10,000.

Knowing your speakers and budget would help quite a bit. What kind of power do you need? What kind of music do you listen to?

Levinson Reference No.33, Lamm M1.1(hybrids actually), FM Acoustics (any model), Krell FPB600--these four brands would have to be at the top of most any list. All quite expensive unfortunately, though in this hobby, not actually the MOST expensive you can buy. Funny how that works.....

Threshold SA/1's mono-blocks.

Well indeed they are nice....but I would like to add the list Goldmund 28+ (I don't think you can do better under 10K) and over 10K try Jeff Rowland 12 or Goldmund 28.4+ mono pair.... Good luck
