Hi Cmrkeung - maybe I can help a bit with this. B&W's should be bi-wired to get the best performance n almost all cases. You hit on the one exception that I know of. B&W's will almost always sound best when using AU24 in a single run with jumpers. I have sent both single with jumpers and bi-wire to at leats 10 of my customers and only one or two have preferred the bi-wire to the single w/jumpers. So if the majority is correct - this is what you should go with. Hope this helps - good luck!
