Mono amps...

are they all basiclly bridged stereo amps or are some designed with a clean sheet of paper as mono amps? I am asking because I have had monoblocks for more than a decade and like the idea of isolating each channel and having the amps as close to the speakers as possible (in fact I miss stereo consoles...just kidding). Being in the market for Bryston 7B-STs, I asked whether they are, in fact, bridged 4B-STs and was assured they are not. Looking at a review of them, however, I read that they are, indeed, bridged 4Bs. Why I should be concerned about this is not clear even in my own mind. I know there are pros and cons to bridging. The slew rate is dsoubled, if I remember correctly. What it all means is a little more blurred. Any thoughts?

I would contact Bryston and see what they say about the bridged 4B aspect of your question. They should know better than any salesman or reviewer.

Bridging creates problems with low impedance loads for most amps. While i can't remember exactly what the deal is, i know that the 7B has some strange numbers for an SS amp when looking into different impedances. You might want to ask Bryston what's up with that aspect while you've got them on the phone. Sean
