I have bi-wired every speaker that I've owned that could be bi-wired, but never heard any difference in sound. Bi- amplifying is the only way I heard a difference. Just try it both ways and see (hear) what you like best."
I do hear the difference in biwiring most of the time, and now that I use just Vandersteens, its 100% of the time. Its a big difference. But if you don't hear the difference, why waste the extra money on getting biwire cables?
