Bryston amps Bridged3B's or 4B?

I recommend you post the same question over on the Bryston Owners circle on AudioCircle. There's a lot of expert Bryston knowledge there--and probably someone who's tried just what you're asking about.

Doesn't Bryston have a bridge switch on the back of their amps? My 3B does.

Are your speakers bi-wireable?

If so, you could go the vertical bi-amping route, without having to bridge (and lose power into lower ohms as Bob R. suggests).

Drive the tweeters or tweeter/mids with the 3B, and get another 3B or even better a 4B for the woofers.

i had the same problem.went with the 14bsst,,,problem solved.go withn the bigger amp and dont look back.
