Antman; I think it is time to step up and buy "real" speaker cable. The original set-up spec for 5.1 is all 5 speakers the same and I assume it means cabling to those speakers also. Most of us do not use the Multi-thousand dollar cables needed to the rear (side) speakers as the length is too long. A good place to start (and consider this a reference to compare other wires to) is Monster Cable "original" twin lead. Not too expensive and 100 ft can usually do the whole room for experimental purposes, or at least the rear/side speakers long term. Next step up smoother sound is Audioquest cv4, have not had success with other cheap/bulk cables, this stuff will also help your bass response. Lots and lots of other combinations but you need to rationally start somewhere, let us know and good luck, Mike.
