I disagree with Markanetz's general statement concerning monoblocks being better than bridged. Different brands act differently.
Although not knowlegable about Bryston, when you bridge them, they kind of become monoblocks. I personally am familiar with the now discontinued Cello products, and in my opinion, the bridged set of the Performance amps blew away the nonbridged setup.
I think I would TRY biamping with another 4B ST stereo amp. You could try horizontal or verticle biamping as well as bridging them.
Also remember double your power only adds 3 db to the volume. If you amps are clipping, this probably won't solve the problem.
Good luck and have fun.
