Lak, long ago I bought five 18KVA cracked high voltage isolators from a store called the isolator store in Iowa or Nebraska. They are heavy. I support the waveguides of my URR speaker wires on them as well as the URRH pcs to components on the top shelves.
I found that the man who ran Rightway Audio was right that one isolator should be between the floor whether bare wood or carpet. I would say that a wooden rack used as you do to hold the waveguides up would be okay and much better than a metal one, but a ceramic isolator would be better.
On the single isolator versus multiple set, I was at a manufacturer's home where he had three isolator rings on each speaker wire. I asked if I might change to only one. He said yes. I had to put the one on speaker stand under each wire with one isolator on top. When we turned the music on he and another listener were very impressed. He said had I not heard it, I would not have believed it!
Glazed ceramic is the best isolator.
