I just went to Home Depot and purchased their XP Monster Cable speaker wire. I got 112 feet for $32. They didn't have enough 12 guage, which would have sold for roughly the same. However, from reading the information here, the XP is only 15 guage, and I am really concerned with the sound quality. I have the NSP1 package, and I have the XBox, and want to have the best connection for 5.1. The longest speaker wire run I need is around 30 feet. Is the XP better than the Home Depot wire, or should I return it and get the 12 guage from another Home Depot, since there is another one closeby. I would really appreciate some advice.
