Belles 150A ref V2 vs Bryston 4BSST2

Bryston has improved over 4BSST w/4BSST2
Less analytical/creamier mids & highs

Not familiar with the Belles 150; but I have been running the Bryston 4BSST 2 and have no complaints; it's a great amplifier. I would purchase another one in a heartbeat! Cheers

It's a solid workhorse amp. It does more good than harm. Is there better, yes of course, but pretty much more expensive. However, I feel the current retail price is a bit high for what the amp does.

Another vote for Bryston.

You don't see the Belles 150a for sale very often and it is relatively inexpensive to purchase but I think it sounds spectacular. One thing to be noted is that it has a very full sound, kind of reminds me of the Odyssey Stratos in that regard. I'm not a big Fan of Bryston bcause I don't think they are very transparent amps & transparency is right at the top of my list.
