The difference between bi-wiring and bi-amping is fairly simple. Bi-wiring still uses a single amplifier channel for each speaker, it's just eliminating the need for bridging straps by carrying power along four separate conductors to the high and low binding posts of your speaker. Bi-amping, on the other hand, sends your amp's full power to your speaker's low and high binding posts, which in the case of my system meant that 250 watts of power were going to my 800's dual bass drivers and another 250 watts to its midrange and tweeter. Bass drivers are typically the hardest to drive, for they require more power than your typical midrange driver or tweeter, due their sheer size. Driving them separately via their own amplification a) puts less of a load on your amp and b) allows the bass drivers to be driven to their full potential for you're feeding them directly, versus having to shift power between an array of drivers. For midrange and high-frequency performance, more power directly fed to the source also equals better performance, especially with esoteric tweeters like the 800's diamond tweeter.

The difference between my 800s' performance with their included bridging straps being driven by 250 watts per channel and bi-amping was eye-opening. Bass notes possessed even greater texture and control than in previous listening sessions. Dynamics improved, as did extension, though I wouldn't say amplifying the 800s' bass section exclusively yielded deeper bass. Midrange performance opened up considerably, gaining speed and transparency in the process, and shedding a bit of Bowers & Wilkins' trademark controlled and dry sound.
