One problem i have with people reccomending cheap hardware store wire is that not all wire is the same. I have had problems in the past with certain brands of wire oxidizing inside the jacket, considerably. And then i have had other wire that didnt. All wire is not created equal. You dont have to spend a fortune to get a respected cable. Radio shacks MEGA cable was one of the wires i had that did NOT oxidize. But that stuff isint very cheap either so any real amount of the stuff would be quite pricey. I personally see no point in using anything less than 12 gauge, no matter how short the run may be unless cost is really an issue. And instead of just blowing the guy off about his speaker placement reccomendations, how hard would it be to just move the speakers and listen to it. He might actually be right. Then again. Maybe not.
