Cable lifters/towers- voodoo or the real thing?

Digsmithd, I wasn't enquiring about the floor finish (the carpet;--), I was enquiring about the floor construction -- what's under the carpet?

Concrete slab-on-grade (dirt), or concrete slab in a highrise bldg.,
OR
wood joists over a crawl space or perhaps over another room, with a plywood subfloor?

.

I have a simple rambler type home...crawl space.Plywood(under carpet) typical 70s flooring type plywood over crawl space...i do have a hell of alot of vibration(pisses me off).Hope i answered your questions?I do wish i had more stable flooring.

I asked because it's the floor *construction* that determines if and what kind of lifters/isolators you might need.

In a floor like yours, inductive interaction from laying on (or very close to, even if there's a carpet) a grounded surface like a reinforced concrete slab, is not an issue.

What *might* be an issue is vibration, and usually this will affect both speaker cables and interconnects (unless you have carpet in which case the interconnects are pretty well isolated by the carpet.

Cable lifters that can transmit floor vibration may not be that much help. A better solution in that case will be swimming pool 'noodles' if you can find them in a decent color ;--) Slice them into 4" - 6" lengths and string them onto your cable. (Gray pipe insulation can also be used but needs to have the seam held together with contact cement.)

Thanks nsgarch for the clarification....your thoughts may be spot on dude.I may go the shunyata route.many choices.

Went the Home Depot route with foam rubber pipe insulators. Looks kinda stupid, what with the insulators on the cables being about 3" in diameter. Don't know if it makes a difference. If it does, I can't hear it. At least it was cheap- like four bucks for a six foot long piece of insulation.

Now- what should I isolate? Just speaker cables? Power cords, too? Please don't tell me to isolate interconnects. LOL.
