I am extremely impressed with my six foot analysis plus oval 9 biwires. My experience is limited, but they might be the best speaker cables I've heard. So good, that if you have to worry, you worry too much ! They sound as good as my $1100 red dawn (didn't direct compare) cables, and (in my system), better than the single wire/jumpered MIT 750 reference. Excellent cable - it just happens to be cheap. I wish I could find some interconnects with this price /performance ratio !

At Audioadvisor.com there are new (old 1999 version) MIT MH-750 Bi-Wire Cables. They would be around $450 to $500 at your length, which is half-price from what they were new at a dealer. For around $200 you could get the new (old 1999 version) MIT Terminator 2 BiWire which is less than half price when at the dealers new.
