Parasound A21 or Bryston 4BSST2?

I think if you want the kind of sound typical of a tube amp, you should buy a tube amp.

Sounds like you should consider some Class A solid state amps. Pass, Plinius, Clayton, etc. Best of luck.

The Sim amp I was using was neutral enough and smooth enough to let all the goodness of a tubed phono preamp (Fosgate) through. So I don't require a pure Class A. Unfortunately that amp is not usable with a heavily damped woofer system. Hence, my search. Just trying to narrow down the candidates.

Both of them are good, solid amps. I'd go with the Bryston just for the simple fact that it's relatively hand made in North America (Canada.) The Parasound is semi mass produced in Taiwan. Also, that Bryston warranty is tough to beat. In addition, the Bryston is better built. However, if you like the sound of the A21 more, then by all means, go for that.
