Which power amp?

I've owned the bryston 3bsst. It is a true powerhouse with an extremely powerful bottom end. I wouldn't describe it as bright or harsh at all. My problem was the bottom end was too powerful - I couldn't control it in my room. Bryston pre-amps - well that's another matter.

Maybe the 2bsst will do the job just as well for less.

Thanks Larry, I will take the Bryston in consideration. I guess it is really a matter of taste, because some folk say the Bryston might be too analytical and therefore it becomes a challenge in long sessions.

My current setup is A90 + CD 192 + DV 88 + T61, but I think my amp is not completely up to the task, as the FB1i's like more power.

For me the contenders are: Hegel H2a / Hegel H4a / Bryston 3B SST / Parasound A21.

Jvilly,
The Bryston is not known for any 'hardness' or fatiguing characteristics...actually, quite the opposite. It's on the 'dry' side of the spectrum overall, but not at all hashy or problematic in the parts of music which can 'tear your head off'. Plus they have loads of slam.
Based on your 'what I'm looking for' description, I'd say that the Bryston might be right for you.
Also, as to your comment about the Arcam CD192...it's not known to be 'hard on top', it errs on the side of softness if anything. (I'm a real fan of Arcam since owning the A-60 a legendary integrated, and my first 'audiophile piece' back in 1978...The inside was signed off by all who completed tasks...workmanship of an extraordinary level I thought. LOVED IT!

Good luck!
Larry
