Bryston amps Bridged3B's or 4B?

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.

Thanks for your responses. To Twoleftears, great idea, I will try that. To Rwwear yes my 3B has a bridging switch also. I have Vandersteens and I don't know how the speaker load varies.

If you search the Vandersteen FAQ page you'll find quite a lot on bi-amping. RV explains that when an amp is only connected to the tweeter/mid terminal, it "sees" the caps protecting the speakers but not the resistive load provided by the woofer. This situation can in turn cause the amp--particularly ss amps--to oscillate wildly, which can cause speaker damage (not covered under warranty).

RV seems to like monoblocks snuggled close up to each speaker. Still, I'm not quite sure about the need for more power, as RV repeatedly makes mention of 100W or at most 200W amps being more than sufficient, and Brystons aren't exactly current-impaired...
