Cable lifters/towers- voodoo or the real thing?

Afc, you never said what kind of floor construction in your listening room, but speaker cables are the most vulnerable to both mechanical vibration (wood framing over a crawl space) and ground inductance (reinforced concrete slab, either on dirt or in a steel/concrete highrise.)

You're right, power cables and IC's are exempt ;--)

If you have carpet etc they work BIG TIME!!

If you have carpet etc they work BIG TIME!!

And what kind of floor construction is under your carpet? And what exactly do you mean by "work BIG TIME"? What do they do, or what problems do they eliminate; and what kind of cables are you referring to?

If you want your experience to mean something to others, you have to qualify your remarks. Otherwise, it's just another empty opinion ;--)

Nsgarch, I have a carpeted floor with plywood underneath....a carpet pad, too. Beneath the floor is the garage.

Afc, OK your problem (if you have one) is mechanical vibration, and not electrical inductance. Standard wood frame construction which meets the building codes, can vibrate a speaker cable lying directly upon the floor or even on carpet. Vibration introduced to the conductors can affect the music signal, but 'if' and 'how much' depends on many factors, such as the construction of the cable, particularly the thickness and material of the outer jacket, the cable's length, the strength of the vibration, etc. So the foam insulators would be appropriate if there is a problem -- but that's the part that's hard to determine.

If your speaker cables have relatively thin outer jacket material, or even none, like the Speltz anti-cables, then isolating them from mechanical contact with the floor (assuming the floor vibrates) should result in a quieter (blacker?) program background, with instruments and vocals having better definition -- but it's a tough call, and only you know if your system is improved.
