Bryston 4BSST2

As far as I know, the bridged Brystons are only able to drive an 8 Ohm load. You might wanna check with Bryston on that. The sound just might be close to the 28BSST2s. Hard to say, really.

Generally speaking, most people feel that you take a hit in sound quality when you bridge a stereo amp. There's a few exceptions, like the BEL 1001. The Bryston 4 is a very powerful amp that can drive just about any speaker with no problems. Do you really need all that extra power?

What are you going to use the 900 watts with? Your user name suggests your affinity for another brand of amps ...just adding to this curiosity.

A hit in sound quality? Depends on the amp, really. Again, what he needs to find out is if the bridged amps can drive a 4 Ohm and lower load.

You're right. Which is why I said this.

"Generally speaking, most people feel that you take a hit in sound quality when you bridge a stereo amp. There's a few exceptions, like the BEL 1001."

I said that because the OP said this.

"My question is... Is the quality of the sound about equal to the 28BSST2's"

""Again, what he needs to find out is if the bridged amps can drive a 4 Ohm and lower load."

Actually, he never asked about that. Regardless, it wouldn't make sense for Bryston to offer the bridge option if the amp couldn't at least handle a 4 ohm load. Most speakers drop down into 4 ohm territory. The company prides themselves on the fact that their amps can power just about any speaker.
