I am currently using the 12 gauge Home Depot speaker cable. I want to maximize the performance of my SVS subwoofer. Should I purchase the Kimber 8PR ($45) or the Better Cables single premium speaker cable ($75) ? Or should I just keep the Home Depot speakers that I currently have. Premium speaker cables seems like a small price to pay to maximize the performance of our $700-$1000 subs. That is if they work.
