In Reply to: RE: Cable lifters....which dampens vibration better? posted by pc123v on August 02, 2014 at 10:21:55
can you show me how vibrations affect electricity travel in a wire please? Is there something I don't know?

Audio is now about insisting on how everything is an enigma, a mystery. In that the notion of religious belief replete with its anti-science basis, and freedom of commerce and the liberty to consume while spending one's own money are the order of the day.
... what we don't know we don't know.
If it's good enough for the CIA, it's good enough for... you get the picture.

Pay special attention to bullet points 3 & 4 in the history section:
"3. An electric current in a wire creates a circular magnetic field around the wire, its direction (clockwise or counter-clockwise) depending on that of the current.
4. A current is induced in a loop of wire when it is moved towards or away from a magnetic field, or a magnet is moved towards or away from it, the direction of current depending on that of the movement".
cable lifting mitigates the nasties created by motion and magnetism and can result in a lower noise-floor, thus allowing more of the oh-so-precious lower level details to be heard.
Everything is going to the dogs

But wouldn't a cable dangling between lifters tend to be more prone to motion than a cable laying on a solid surface?
At least I gather you are not pulling these cables tight and anchoring the lifters to prevent motion.
The EMI field generated is of interest. There is a reason why high voltage cables have very long insulators beyond the voltage implications. They utilities want to minimize magnetic interaction with environmental factors.
Magnetic fields are a oft neglected facet of any AC transmission. A vacuum is the best insulation but barring that air wrks second best. To fully isolate the magnetic influence, try using Z sleeves. The Z sleeves are modified zero gauss chambers and serve to isolate the magnetic field generated by cables from the environment, in addition to shielding th cables from external EMF influences. The work extremely well and even a 6 inch section thus shielded gives a noticeable increase in sound quality: dynamics and detail.
Of course YMMV and FWIW
So are you saying that a wire, that is moving, with current flowing through it will move into it's own magnetic field thus producing unwanted voltage in the wire?

"Still Working the Problem"
what I read from this article is that it MAY be beneficial to keep each speaker wire run separated, especially from AC powered cables, but I am sorry, I cannot see where vibrations impede an electrical signal through a wire. I am not an electrician, but I have taken courses in college and wired many, many homes as a contractor.
