Biamping -- any good?


Recently, I read a speaker review in which the reviewer indicated that biamplification (versus use of the conventional single-amp configuration) had noticeably improved the sound quality of his speakers. I find this to be very interesting; however, having no experience in this area, I was wondering if anyone would care to share their good/bad experiences? The info you provide will assist me in determining whether I should pursue this aspect of audio or not.

I have a pair of Magnepan MGIIIA's that I want to bi-amp using the Magnepan supplied passive crossover. The configuration is as follows: preamp out to passive crossover, midrange/tweeter out to mid/tweet amp directly to mid/tweet connection on speaker. Bass out to bass amp to crossover(standard outboard Magnepan crossover) to bass input on speaker. This is the recommended Magnepan setup, also providing correct resistance in first passive crossover for mid/tweet and disconnecting mid/tweet capacitors in second crossover where bass amp is coming in. Anyone have any experience/knowledge of results? I am using two Krell KSA-50s to run. Thanks

The following is from B&W tech support is response to my question about BiAmping the B&W 801 & 802 speakers. "We did not make an external crossover for the Matrix series for use with bi-amping. Once again, bi-amping with an external crossover changes the characteristics of the speaker outside of B&W's design, effecting performance and voiding the warranty (and can cause damage if not done properly).
Is there any harm in using 2 identical amps to power the high and low section of a speaker already set up to be bi-wired. It was explained to me that this was simply the next step up from bi-wiring from a single amp.
Unless you have electronic crossovers, or just need an extension of your manhood, spare the costs and put it into a better single amp.
