bi-amp

bi-amping doesn't do anything. your receiver is limited by the power supply, not by the channel output. technically the way receivers do it is called bi-wiring. bi-amping does do something, but you need 2 amps

I personally bi-amp my speakers and feel that they sound pretty good. Haven't tried traditional way, so can't for sure tell if there was an improvement with Bi-amping. There is a large contingent of prominent audio gurus saying bi-amping using a single receiver does not achieve much benefit, and would need a separate amplifier per channel set you are trying to amplify independently. I do it anyway because I have amp channels to spare, and nothing more to lose than paying for an extra pair of speaker cables..

actualy, because the tweeter only gets maybe 25 percent of the power anyway, biamping can't increase available power enough to make more than a decibel of difference. And if you're not clipping, you won't hear a difference between biamped and non biamped. That said, I biamped my Sonus Fabers and my Magnepans and everything worked dandy.
