Bryston Cubed Amps in Bridge Mode

I had dual 2.5B3 amps.  I found it was hard to find any specs into 4 ohms on them or any Brystons running bridged.  Research threads into bridging and they will discuss the downsides of this.  Using Revel 228 Be speakers, which have 2 pairs of binding posts, I found I much preferred running them non-bridged either in a vertical or horizontal biamp configuration.  Bridging them did not add any beneficial sound quality and in some cases sounded worse.  If you think you need 3-400 watts per channel, I would buy the bigger stereo amplifier.  

@jimmy2615 What benefits did you find running the amps vertically biamped? When you vertically biamped, did you use shorter cables between the amp and the speaker? I tried (for a short listening session) my amp (not Bryston) bridged last night and did not find it sounded better, in fact, it seemed the bass was less defined. As many others, I thought more watts would sound better.  I am going to try again this weekend. I suspect the damping factor was the reason.

With most bridged amplifiers, distortion goes up and the ability to drive lower impedance goes down. Who wants that?

The exceptions are amplifiers that "bridge" by paralleling outputs, such the McIntosh MC75. But even then, some users say it sounds better in stereo.
