Bryston VS Musical Fidelity

I've compared and used many solid state amps. The Brsyton SST series amps offer great sound quality within their price range and up. As a matter of fact the only amp that has sounded better (in my current system) than my 4B-SST, has been a Pass Labs X-250.

Bryston amps have some of the best bass I have ever heard, solid, fast, and extremely well controlled. The SST series have very competitive mids and none of the exaggerated highs of the much earlier models.

As far a a MF to Bryston comparison, well... you can see I have no MF gear. They make fine products and I have never heard a MF piece that made me say, ugh!

Has any one listened to the Bryston and Belles amps side by side? What are the sonic differences? Also is there any difference in the Bryston line between the 4bsst and say the 14bsst or 7bsst mono's, or is it just headroom?

OK. Let's throw another amp into the mix.
How about a Rotel RB-1090? That's a
380WPC dual Mono amp. Two transformers
four power supplys, plus it's only 2K.
Thoughts....
