The finest Cable Elevators you ever auditioned?

"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.

Actually I've recently discovered that some digested substances may increase audible frequency range. I'm planning to launch production of such vials that will be FDA approved and purchased with no RX. There are different formulas for different styles of music you're listening to.
Consult your doctor if you have alergies etc...
Price per weekly dosage vials =$$; monthly dosage etc... Morning, afternoon and evening formulas available. A special order is needed for night formula for night listeners. You can even match proper formula to the system components you have...
Just lovin that audiophile market LOL where sky is the limit!
