Cable risers.
Cryo treatment.
Bogus.
Perhaps, you are right, but then, perhaps not. Consider the following use of cable risers. There are a pair of network cables in the plumbing jacket against the wall. There is a power cable for the sub (which you'll notice is the basic, stock cable) running along the front side of the cable risers. The sub output of my XO, the LFE output from my preamp and the speaker wires for the rear channel all run along the risers. This maintains the segregation of my signal wires along a parallel path with the aforementioned. That, I think is sensible - not a bogus concern. Ergo, such tools can serve a valid purpose, even from a most restrictive viewpoint.
Whether or not they may also provide a benefit by elevating signal wires above the synthetic fibers of the carpet is a matter I'll leave to others to argue, but they do provide other benefits which are of value to me. Hell, as someone pointed out in that other thread, they look 'kewl' (to some of us anyway). As they have a fair amount of weight and the wires can be strapped to them, they are convenient for routing purposes - being elevated forces any other individual walking in that area of the room to 'respect' the speaker wires. I should also point out that the porcelain insulators that I purchased for the task are quite cheap when sourced from an electrical supply house.
