I'm sure you'll get a few observations but having owned a number of Bryston preamps and amps over the years I can attest that Bryston preamps mate superbly well with their own amps. Something has to be said for synergy between components from the same manufacturer. It makes perfect sense that a manufacturer's desired outcome for a particular product can be realized when mating that product to other products "in-house". I can't say that Bryston amps are overly warmish in nature but they are dynamic and transparent, at least IMHO...
