Dave, shortly saying for the entry- level Brystons are perfect - no comment. Much better than Classe, Krell or even Edge. They worked real great with my Totem Forest speakers. I used Bryston 11b preamp for a while and realized that it sounds too far away from music and I stepped into the different level when I traded 3b-st/11b for VTL MB100/passive preamp instead of Bryston components and entered entirely different world of musical reproduction. Let Stevie Wonder love Bryston but some of the home recording studio owners have Manley electronics and this is believe me alot different.
Aball, bipolar transistors have the highest rate of parameter instability. If you analyze the output curve set for different impedance loads and freequencies you'll realize when and where the bipolar element will "choke". Bipolar elements compared to MOSFET or tubes need an extreamly deep negative feedback in order to work in linear operation wich certainly causes the signal to be compressed.
