I have seen a lot of ideas concerning Cable lifters

Does anyone have some factual information on whether cable geometry affects the amount of capacitance with respect to say a floor being nearby?
For example:

• A quad core design IC, inside of a conductive sheath would seem like it would not change capacitance as it gets near a floor.
• A single unchecked speaker cable would surely see other things as they approach the electric field.
• and with some woven speaker cables, maybe they are more immune to the floor as the cable would effectively not have very much of an electric field as they are canceled by the weave.

Does anyone have some details on ^that^, or some empirical observations of which cables like a riser, and which cable are unaffected by the use of them?

@holmz Concerning your capacitance question, I might sound like I am on the negative side here but I seriously doubt that 'Capacitance' is the issue. That is unless the effect caused by the floor causes a parallel capacitance which would then modify the value of the internal cap as designed by the manufacturer. If you look at the formula for how a capacitor is rated, the air dielectric and the huge variety of materials that make up common floor coverings would create such a tiny capacitance it would not even be seen. I mean like, NOT in the same universe.

I sort of agree - but that “bunking video” posted earlier showed the capacitance changing.
If is is not capacitance, then there is only inductance and microphonics… if we assume that the resistance is not affected.

or we are left with pure imagination… but the bunking video was somewhat compelling that something electrical is happening, and they were measuring capacitance... Hence the reasoning behind my question.

I think asvjerry hit the nail on the head with pipe insulation.
