Interesting you mention the Radio Shack cables. I have tried and used the thicker RS gold series a/v cables (yellow and white rings on the ends instead of red and white) because of a dimmer switch problem and I think they're fine. No frequency anomalies, good three dimensional palpable images. Depth, spread, isolation. No problems. Now, if anything, I have a bias in favor of the underdog, so I dont want the more expensive stuff to sound better. But Im also honest with myself. I actually prefer the Radio Shack cables to some cables, and cannot say for sure that I can detect a difference between the RS cables and, for example, Kimber PBJ. (I love the looks of the PBJ and want to like them more than anything.) In addition to the RS GOld A/V cable, I use Kimber Silver Streak and I think its more open and lets some more detail through, and I also use some $40/pair silver plated copper center coax with locking RCA's made by a local pro gear maker that I like the best. Now I know silver plated copper is not suppose to be good, but Nordost is doing it (didnt know that til later).
As suggested by another thread around here, and the designer of my favorite speakers, I'd rather leave well enough alone and enjoy the music through the equipment I have. I know it isnt state of the art, but its enjoyable. If you aren't unhappy with the wires you have then who cares if they sound different from other wires? If you have no wires at all, buy something inexpensive and dont obsess.
