I actually used cable elevators that I made myself. The base and uprights were made from oak with some monofilament strung between two stainless steel angle brackets. I used this to keep my speaker cables off of the floor. It was not that I was worried about my electrons getting bruised but I was worried about the dampness from a poorly waterproofed and insulated concrete slab in the house i was renting at the time.

As far as all cables being equivalent, most of the arguements center around the fact that wire is wire and copper is copper. But for audio interconnects, video interconnects and digital connections you also cannot dismiss the quality of the connector. Almost every cable that has come free with a component I have purchased (and some quite expensive) has had what I considered poorly constructed connectors. This may be more important for video connections where many cheap connectors do not maintain a 75 Ohm impedance. I personally noticed this when hooking up a television to digital cable a few years back. The picture was very soft and fuzzy with a premade cable. When I replaced it with a home made cable with Canare true 75 Ohm connectors the picture became sharp. I then took the pre-made cable, removed the connectors, replaced them with Canares and low-and-behold I had a sharp picture. Whether this is as much a factor at audio frequencies as for video is up for debate but I personally like the secure feeling of using locking RCA's like the outlaw cables have.
