Cable / Upgrade Recommendation

I always thought of Enid Lumley as a comical figure but after seeing the recommendation to raise cables off the floor repeated here and at Mapleshade, I figured, what the heck, like chicken soup, it couldn't hoit. I cut the flaps off a cardboard box, folded them in half and cut a "v" into the fold to hold the cable. Darned if there isn't a very slight improvement in image and treble "air". BTW, it's worth repeating that replacing the outlet in my apartment with the Pass& Seymour that I got from Kevperro made a HUGE difference, as much as the Asylum cables themselves.
