Biamping B&W 802 with Musical Fidelity and Bryston

Biamping with identical amps does NOT double the power because the energy spectrum of music is not uniform. The power gain, if any, is marginal. A single amp with twice the power is more but, still, not more than a few dB.

It's a good point. I did not think about it.

There's nothing scary or hard about bi-amping, and the audible benefits are many. I've been actively bi-amping for years(tube top/SS bottom), but it's much easier with two identical amps. Read this: (http://www.soundstage.com/synergize/synergize031998.htm) It contains tips/facts on vertical bi-amping that you might find enlightening.

In my opinion neither of those amps are "nice" on the top. I was an MF dealer and used a 4B for an hour in my system before I just had to remove it. Very metallic sounding to my ear. Too bad too I really wanted it, they are well built and as it was a trade in I could have gotten it cheap. I settled on CJ SS amps. I first got the 100WPC MF2100. Nice. I then got a MF2500- 250WPC and put the 2100 in the closet. I then bi-wired the 2500. Big improvement. I then decided hey these two amps both have the same gain,input impedance and sensitivity. I then implemented a horizontal bi-amp. Again another level of improvement. Not subtle either, especially in image and soundstage. Read Rodman's link too, it's good.

I agree with most here, sell the amp and get one amp which will do both or two the same to bi amp. I like electroids reccomendation, MF2500, but maybe I'm biased, trying to sell my MF2500A, ha, but I did biamp with two amps diferent manufacturers, cj mf2250 and rotel 1080, when I got rid of the rotel and added just the mf2500A it was much better. I didn't try the biamp with the two cj pieces because I just decided to get a whole new system. I geuss the point is the 250 watts not biamped was much better than two lesser amps biamped. I have a large room though and needed more speaker and more power, so selling all.
