I've owed a lot of Bryston separates, but never one of their integrated amps. With that said, for the most part, they merge the preamps and amps to create the integrated. Example - BP6 + 2B.
The SST series is where Bryston, IMO, got really good.
Bryston has fantastic bass control and impact. Overall, they are neutral. Paired with a bright speaker, they can come off as bright. However, that's just the byproduct of a poor amp/speaker matching.
