I agree with Big

Phoenix Gold speaker cable is very inexpensive and very good. I have their 12 Ga silver series OFC, and it's just excellent. I hear some Monster for 3.50$ a foot, and it was the same as the Phoenix Gold at 75 cents per foot. I HIGHLY recommend Phoenix Gold. You can buy it online at partsexpress.com and 123av.com

if you live near a StereoPlus, they have it in stores for very low prices.
