Rsbeck's suggestion of examining one's room and system configuration to trouble-shoot a sonic problem makes common sense to me. It's possible that folks asking questions about cables as a solution to a problem haven't considered whether room treatment, or a component is to blame. No disrespect to you, Harnellt, if you've already considered...and eliminated...these variables.
I believe cables do sound differently. However, no cable is going to properly solve a problem if the root cause is a component, or a room that lacks proper treatment. I owned loudspeakers that I found terribly bright and lacking in bass. I tried several different cables, and I heard only minor variations between them and not enough to fix the sound of my system. Eventually, I changed speakers. Changing speakers made all the difference, and I would have saved myself a lot of time if I'd changed them sooner.
