To bridge or not to bridge....

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.

Richard,
First we've got to make sure that the author's speakers are bi-wirable. Second we need to know what kind of speakers are we talking about that even Bryston 4b-st doesn't have enough current to swing a woofer(is it some 1000W woofer??)

7b-st as suggested by Ozzfly is basically the same thing as 4b-st but made as a pure monoblock and certainly sounds better than bridged pair of 4b-st. Thus in the case with Bryston and with most brands it's much better to go for dedicated monoblocks instead of using bridged pair.

And at last the question:

If I have amp 1W/ch and I want to use a bridged pair will I add 3dB to the volume?
I guess not! The whole different issue when you double 250W/ch or 200W/ch isn't it?

My speakers are Kef 104.2..92 db..4 ohm and they have a single binding post only.
I have contacted Bryston,regarding this problem,on the off chance there is a technical fault.
Haven't heard anything yet.
Thanks ,so far, for the info.

Yep, the truth is there that your unit needs to be checked.
Good to have 20yrs transferable warranty though!

Bryston replied "very unlikely that there is a fault.Amps usually work or they don.t.
I guess I'm under powered or need hearing aids.
