Need feedback from Bryston amp owners

I owned the Bryson 4B. "Strong in the low end (bass)?" How about powerful, solid, extended and visceral. As good as I have heard in SS. In my DJ days I used the 4B animalistically. 4 hours (six on New Year's Eve) with the clipping lights blinking like mad. Never overheated/distorted. A work horse. In my home system: a strong B in the midrange and treble coupled with an Audio Research Pre.

My 4B never had a problem running tough loads. Ran Magnaplanar Tympani 1Ds. Talk about a difficult load. 4BST and the 7BST? No experience, but the 4B was a gem. Don't they still have their 20 year warranty?

"unrefined top end" never thought of putting it that way, but that may give you more than my B rating: I agree with Tvad. The midrange is wonderful (maybe I was a little too critical B+), and just misses greatness. Still a honey of an amp in the right rig..

Depends on the speakers. The 3B SST is wonderful. I heard it driving Sonus Fabers and it was lovely. If you don't need the watts, the little guy should do the job for you.
