Sorry, but I must ask why you think you need more power? The B100sst should be plenty for the Sonatina, which I think is a 93db, 8 ohm speaker.
bryston b100sst as pre-amp
I have been using my Bryston B100sst integrated amp for some time. Considering going back to separates but can't afford to go whole hog all at once. I have Silverline Sonatina speakers (1st edition), Oppo bdp105, Morrow sp7 biwire, Darwin Ascension 2 interconnects and Signalcable power cords. I would like a little more power. So, I would buy a used power amp and use the Bryston as a pre-amp until my ship comes in. Any suggestions would be appreciated.
Thanks,
