Hi! I hope I can answer your question. Before selling my Klipsch system about a year ago. I too wondered if it would make a difference so I ordered a set. I didn't order it purely based on looking for a sound quality increase but I also know that any wire -- even monster will have better quality and will be more rugged, will be able to sustain more punishment from stepping over them, running them over with my desk chair once in a while etc. Well, the quality was very well done and after all the beating its been through, the cable still looks brand new. Sound quality wise, I thought I heard a pretty good difference in the midrange. The highs wern't as harsh as they used to be. But the biggest thing was: better midrange for sure. Much more smooth and prominent. Bass? Of course, no increase because the wire runs from sub to satts, not affecting the subwoofer's performance. If money isn't too much of an issue and you can lay down 30 bucks for it, then i recommend them if you're looking for much better quality then those little tiny wires they give you or a slight increase in midrange quality. Hope it helps!
