Now I know why my setup isn’t audiophile grade"triboelectric draining carbon sheath"...
"rhodium-plated connectors"...
LOL.
Triboelectric effects are not static electricity. It is when physical movements cause noise. The funny thing is that the two materials the worst in this regard are silver against Teflon. So their choice of materials creates a problem which they then solve with a layer of carbon. Can't make this stuff up.Wtf is a "modulation cable"? How do you get static electricity (triboelectricity) build up on something covered with a grounded shield?
Rhodium is a solid choice,but all others..."triboelectric draining carbon sheath"...

Does not conduct as good as either copper or gold... Also more expensive.Rhodium is a solid choice,but all others...
Shielding cannot be relied upon to conduct that effect away. Or I should say when it does that is what creates the noise. Microphone cables move when your singer is moving around. For line level home use a complete non issue.Is it not the static that makes the noise?
From Wikipedia: Often static electricity is a consequence of the triboelectric effect when the charge stays on one or both of the objects and is not conducted away. The term triboelectricity has been used to refer to the field of study or the general phenomenon of the triboelectric effect,[1][2][3][4] or to the static electricity that results from it.
Dosnt the shield conduct that away any way?
And when do cables move?
The difference in conductivity for less than a mm is negligible. Gold and copper are soft and will wear and copper will corrode. There are cheaper materials that do the same thing as the rhodium.Does not conduct as good as either copper or gold... Also more expensive.
Sure I can see it with mics and a lot of gain. I have never seen a singer hold a mic while recording in a studio. I would think the mic handling noise would be a bigger concern than triboelectrics.Shielding cannot be relied upon to conduct that effect away.

I at one time recorded the level of this effect in several cables and posted the files. It was high enough to be a minor possible issue with Microphone use with one cable.
With most cables it is not a problem, but I have found one where it can be. Monoprice Premium XLRs. Fine cables, but they have extra layers of shielding, and just a conjecture, I'm guessing this creates more triboelectric effect. They exhibited more of this than any cable I tried. Only a possible concern with cable movement on a microphone and not much of one then. No issue for any line level use, nor a microphone on a stand with the cable simply lying on the floor.Sure I can see it with mics and a lot of gain.

Why is this not a problem with guitar cables? Lots of gain into very high impedances.
