This topic has been covered in several posts (over and over) recently. As I recall, both Ian and Alan (and I am in agreement) recommend good quality 12 gage stranded copper wire. (and yes you CAN get it at Home Depot or Radio Shack - and even Monster Cable will work just fine!) I know Ravi is enamered with some stuff from Kimber Cable - but I believe you would be better served to put your $ in good equipment and not overpriced "exotic" speaker wire.

Good Luck
