"Is there something out there under $1000 that really is a giant killer? "
I'm guessing almost anything home made that works. If its elevated, its elevated I would think.
Practically, I'd first work to avoid EM interactions among cables by arranging them carefully to avoid long close parallel runs. I would expect that to effectively address any issues associated with wire location, relative or otherwise.
I do not see why elevating a wire in of itself is necessarily even a good thing. The thing to avoid is EM field interactions among wires and other electrical devices. Elevating alone just to elevate might help but could make things worse as well if not done properly. The best "elevator" to accomplish this would be anything best applied to this end. I would not expect there to be any benefit in paying a premium for some device to do this marketed to "audiophiles" unless perhaps there was some cosmetic or aesthetic advantage involved.
