I currently use a pair of Cat 5 cables I made myself. Each cable contains 4 cat5e cables twisted. 2 for +, and 2 for -. If I remember correctly, each Cat5 cable contains four pairs of 24ga copper. So eight strands of 24ga copper per cable. Some cat 6 is 23ga. There is also Cat 6e now. The "e" stands for enhanced. It has a different and tighter twist pattern. I do believe that "data" cable based speaker cables have a higher capacitance cable as many have said. Not sure what that's based on but they seem to work fine for me. The way I understood it was the thought that the copper wouldn't oxidize as fast since they are individually sheathed, and since several small strands are better than one solid strand due to eddy current effect, I figured I'd give it a go. How does the high capacitance affect the output? I am not a speaker cable or interconnect wiz.
