Paul McGowan up above goes into detail on the matter, says it doesn't matter with regard to biamping, then recommends biwiring! Holy smoke! I knew he liked wires. Meanwhile, the rather overworked video referenced on Matthew's post up above really does a good job showing that biwiring is nonsense from an electrical standpoint. I have to admit I am skeptical about those thin metal jumper straps often supplied. The KEF's I'm looking at has that internal so you would have to guess that's real wiring. Don't know about the PSAudio speaker. I would like to hear some thoughts on those 2 speakers I was looking at before I release the $$$. As far as the biwiring goes, I think if you have the cabling already (I do), at least it wouldn't hurt. If you don't I would spend the money elsewhere, maybe starting with better jumpers. Thanks for the comments!
