"Hi I just got a Bryston 2B amp today and was wondering what people think of it"
------------------------------
All that really matters is what you think of it. And since you have a Carver amp to compare it to, Which is no slouch either, this should help you determine which is best for you. Play them both at the volume you listen to mostly and go from there. Myself, I value quality over quantity with respect to power, after all, a lot of the better AVR's out there can rattle the walls with bass, and produce concert level SPL's. But only the better amps can retrieve the small nuances in recorded music that makes it sound like the real thing too.
The 2B/3B/4B series Bryston amps are their first edition amps. The 2/3/4B-ST models are I believe a noticeable step up. That said, the first edition models are likely as good or better than most amps anywhere near their price range. It should sound outstanding operated under clipping driving just about any speaker made. Pretty much neutral in its presentation it will reproduce whatever you feed, Nothing more, Nothing less.
