Mapeshade cable lifts or any cable lifts?

"Theoretically, the good ones should be able to improve the sound especially at high volume."

Many of these tweaks and "theory" should not be mentioned in the same sentence. They may or may not work, but there is almost never any theory behind them, or a huge stretch at least.
Same here. Cables vibrating? I don't think so.
Unless you're talking about the theory you conjure up in your own head. Then it makes perfect sense, theoretically of course.

Not to mention the static electric charge on carpets.

The comment on theory is too true.
I think Humans like to have 'reasons' for stuff, and so invent personal theories on the spot to self explain phenomena they do not really understand.
So all sorts of 'theories' are created to 'explain' the unexplained. The flaws in those theories do not invalidate the odd things going on in some tweaks.
They just mean no one has scientifically bothered to track down what is actually happening there.
So all those 'Cosmic' whatever theories of 'Quantum this or that' sound like crazy rubbish, and probably are crazy rubbish. But the actual fact of something occurs is real, (most of the time,anyway!, and somethimes it is too subtle to notice in a system, sometimes it makes a major effect. Then i have noticed the effects are cumilative. Several tweaks add up to a result.
Thus I have been doing stuff (free or nearly free) and just adding them, and lately got a great result from one (pigtil tweak with ferrit cores added), and i am certain it would not have been as good a result if the other tweaks had not been done.
So i am a tweaker, but ONLY for real cheap or free. Skip the expensive ones, as nearly all of them have a cheap or free analog. And i am skeptical, and really i have to laugh at some claims. But the problem is some of this stuff works. And that is why i am interested in it.
So my take is if it is free and easy to do what the Hell, try it. (though a few things are too far out for me too... LOL.. (Geoff, a comment for you!!))

"Cables vibrating? I don't think so" I bet you don't think that speakers vibrate either.
"Quantum this or that". That happens too of course, but that's not what I was talking about. Elizabeth, you want something good for nothing; special treatment, in a manner of speaking. I can understand it; good luck to you.
Interesting thread anyway.

I don't know about fancy lift products, but there is usually benefit to keeping the cables off of the floor. Especially carpet over concrete. It could be a capacitive interaction, I don't really know. Lifting my speaker cables did result in a bit more blackness in the background.

We Galibier owners have often demonstrated the effect of lifting the battery power supply off of the floor. There is no change in speed, but there is a sudden effortlessness when the battery is lifted. It seems that after these batteries have been sitting on the carpet for a while they also build a little capacitance. It can be demonstrated again, but the battery has to be used sitting on the floor for a while to build the effect back up.

Vibrations in cables do matter, but I don't think any of our stereos can put out that much energy to do this through signal power. ;-) However, try tapping on an interconnect lightly and see if you hear it through the speakers. This tells me the cables just need to be left alone, not nailed to the wall or something.
