Bi Wire vs Speaker Jumpers

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.

I prefer jumpers to internal bi-wire, but prefer a double run.  Read the Vandersteen website about bi-wiring...

@lak is correct in his advice to you.

An additional point, as you are playing around with bi-wiring (from the same amp) try crossing over the separate runs (hi vs low). This can be helpful as well.

Further, the cables (and amps) don’t need to be exactly the same either, as some prefer to fine-tune the hi and low frequencies. I’ve had good outcomes using completely different cables and amps.

In my experience if my amp and speakers are both Biwire capable I notice the layering is much better, I will strongly recommend to Biwire if both are Biwire capable, If the speakers are the only one biwire, I go buy a good quality jumpers..

Agree with Lak you have to experiment , different system different result....
