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.

@12many I didn’t do enough experimentation to say one way or another that I preferred vertical to horizontal or vice versa. It certainly is more convenient to have one amp close to one speaker and thus used only short cables. But overall or in either case, having a channel (135 watts in my case into 8 ohms) to run the woofers and one to run the midrange/tweeter separately is like what they do with active speakers. There’s a lot more headroom, everything sounds clearer, and strain free. I assume the amplifiers also see a different (and perhaps easier) load to drive as well since the impedence load we generally see for a speaker is all the drivers taken together. But I’m no expert, just a guess on my part, |
