Hi All, Recently just for fun I purchased a short run of "expensive" speaker cable ($9/ft) and have been A/B-ing it in my system with great delight. I used to believe that there wasn't much difference at all and that cable was cable. But now I have proven to myself that there are differences that I can hear. And maybe some of that expensive cable is really worth it. I'm wondering what cables people use and how your understanding has changed over time?
