Honestly, each speaker brand is different. Some speakers sound better bi-wired and some sound better using jumpers. You really have to try it yourself and then decide. I've owned a variety of speakers and I've learned that what I said above by trial and error. I've read somewhere (and I can't locate it at the present time) that states the specific reasons that some speakers benefit from bi-wiring and some don't. It had to do with the way the speaker was built and wired internally. I've never owned B&W 802 speakers so I have no opinion other then to say try it both ways.
