I agree with several others on this subject that the Canare 4S11 oxygen free cable is the way to go and make 'em up yourself with banana plugs or whatever you need. I run two 14 footers without a hiccup from my system. Performance audio in Utah can sell it by the foot or premade at a higher price. Good service and quick shipping.
I agree with square80 and not purchasing boutique cables.... spend your hard earned money elsewhere...they ain't that significant.
