The upper end Rotel amps are very good. I was rather impressed when I heard them. The voicing is very slightly on the warm side (it has just a bit of a warm texture), but it still has excellent resolution.
The Bryston 3B amps are on the complete opposite side. They are clean and neutral sounding. However, they can sound a bit thin and without texture on some systems/speakers. I would generally recommend these latest Bryston amps if you have a very warm/slow preamp.
I own the B&W D3 speakers and tested some Bryston 7b3 monoblocks. I was able to get them sounding good with a fuse upgrade, but they just could not keep up with the other amps I had (Parasound JC1 and Emotiva XPR-1). The Bryston’s just sounded weak and thin in comparison. They did not have as much midrange/midbass body and it seemed the upper mids/highs were too clean and lacking grit/texture/resolution.
Other people may have different opinions/experiences.
