EEMAN and Jimna:

I am more than a little confused about the claims of a skin effect and surface area on 12 gauge wire. I could understand that claim if one were discussing a solid core 12 gauge wire. But most 12 gauge speaker wire is made from dozens, if not hundreds, of smaller strands that I believe have a larger total surface area than the cat5e cable does.
