I am glad this came up, pulling the trigger tonight on a m80 setup and am now thinking about the details i.e. the cables.
I already read about high end cables being snake oil, so I am ready to do a bulk wire purchase.
Someone mentioned Home Depot, I just wanted to throw one more out there I am thinking about...Any advantages on using cable from monoprice.com? I found bulk cable here
I noticed they had gotten a best of 2006 award from secrets of home theater site.
