Amp upgrade from Bryston 4B

Thanks for the responses. The pre amp is currently a weak point in the system. After spending the wk end using the Outlaw Audio processor in bypass mode for 2.1 listening I switched back to my passive preamp which is a big improvement in clarity and much more pleasing sound. I will eventually replace the Outlaw Audio processor, but 5.1 surround listening is not a priority. Therefore, I am concentrating on upgrading the stereo components first.

My current Bryston 4B amp with the passive pre amp has been a good match for the Thiel 3.6 speakers, but would like to upgrade. A bryston pre amp with a bryston amp has had good synergy reviews. The bryston pre amps have a stereo selection that is not a true bypass for fully using a surround sound processor.

Some of the fd back on this thread has indicated that a bryston 14b amp would be a good match with the Thiels. My understanding is the 14b amp is essentially two 7bs combined in the 2 ch amp. Any reason not to lean towards the 7b mono amps vs the 14b? Some of the other recommended amps with are also worth considering with a pre amp upgrade.

I believe some say the 14B sounds better. Don't hold me to that, however. According to Bryston, the 7B has more capacitance than the 14B, plus you can run shorter speaker cable, always a plus in my book.

step up to the 4B SST.

Or SST2, that's not a bad, and cheaper, idea as well. But stuff like Pass Labs is in another league.
