Biamping B&W Nautilus 803's

http://www.bwspeakers.com/service/getthemost/ has a section on bi-amping and http://www.bwspeakers.com/service/faq discusses changing the internal crossovers (i.e. disabling them) as well as introducing active crossovers. Note that they almost dictate that you should bi-wire even though they provide jumpers but warn of difficulties beyond that.

But I have N803s too. And wouldn't it be nice to bi-amp ? I was thinking of using 4 of the channels of my 5 channel amp (Pass Labs X5) for a passive bi-amp of the N803s and the last one for my HTM2 center, bi-wired. Then a separate, cheaper, stereo amp to run the Signature 7NT surrounds. Trouble is that I've got balanced connections and I haven't seen Y's in this config, other than cheap microphone type wires. Anyone have any thoughts ?

Welcome. It looks like that from your profile you've just arrived. A word of warning. While this isn't like Yahooligans you may get flamed over your premise that biwiring doesn't do anything. I guess I'll be the first. Sorry. B&W make it pretty clear that they expect the normal hookup to be via bi-wiring. Some folks around here use completely different wires for tweeters vs. mid/bass. Thinking about it my bi-wire setup has silver for the upper frequency and pure copper for the lower. Guess I went a little overboard on that one. I'd love to bi-amp, and am sure it would make a difference. But it would make a difference to my wallet, my relationship with my wife (she'd notice another box, honest), just to improve the sound on a system that I already enjoy daily.

By the way my power amp seems to deliver anything that's necessary, including heat (I'm in Tahoe and it's damn cold right now). But it would be nice to use quality power to my mains by using 4 of the 5 channels.

Again, welcome.
