Don't bi-amp. You'll get better sound (and a simpler hook up) for your money buying one better amp than two amps and an electronic crossover for the same price. The comment made in the one of the other statements from the B&W sales reps was succinct, concise, and correct.
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.
