Cable lifters/towers- voodoo or the real thing?


This is something I've been wrestling with for some time. After spending as much on equipment as I have, I'm hesitant about dropping a rather menial sum on cable lifters or towers. It's literally the cost of a few cases of premium imported beer, but I just can't believe what I read about them. Six Moons glowed about Dedicated Audio's Cable Towers, but I'm not sure if I buy it. Perhaps it's because I don't understand the reasoning behind them. Any opinions or thoughts to educate me here? Am I being an idiot not getting any? Right now, I just have a tangled mess of cables lying on the floor, suspended in air from being relatively stretched....is it a good way to tweak a system?
afc
Digsmithd -- I'm curious. What kind of floor is in your listening room: concrete slab or wood floor over joists?
I have wall to wall carpet...so they are"necessary".I also have small shunyatas for cabling.As i said its something you just have to try for yourself and either works and you hear it or you dont?
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.)
