Cable insulation, graphene, electron flow... how does it work?

From my limited experience with graphene pasted on fuses, it appears to work when painted on the glass only. And I know that graphene painted on the exterior of capacitors can help improve sound quality, presumably by facilitating electron flow to and from the capacitors. I know graphene works on any exposed wire or solder joint. It also works when painted on the insulation of cables. It does not control vibration to my knowledge. Therefore, something crazy is happening whereby the graphene is facilitating the flow of electricity, even when applied outside the insulation.

I want to treat the inside of my old preamp with graphene paste, and I want to try it on insulated wires connecting the tubes and transformer. But there are places where one insulated wire touches another. If the graphene is really operating at some level outside the insulation (and I'm not claiming to know for certain that it does), would it cause a problem if the insulated wires are touching and coated with graphene?

Strawman alert. Electrons don’t flow. Besides, from what I can tell a few layers of Graphene will still act like Graphene, though perhaps not to the same extent as a single one molecule thick layer. So painting a very thin Graphene paste or “solution” on wire or a structural part or a solder joint or a fuse cap might not be such a terrible idea. Also, being very highly conductive, Graphene would make an excellent RFI/EMI shield, no? Not to mention the proposition by some that a percentage of the signal travels outside the conductor.

Had to google what y'all were talking about. Interesting.

It works on exposed solder joints, that I can say for certain, since I carefully covered every accessible solder joint in my preamp (over 100 joints) with graphene paste. The cumulative effect on sound quality is extremely positive.

I was impressed with Joseph Audio Perspective2 Graphene speakers that I heard at AXPONA. I believe they have graphene coated Magnesium woofers.  I also thought the previous version of the Perspectives sounded good too so I suspect it isn't necessarily the graphene that appeals to me.  It would be interesting to A/B both versions.  I'm not sure I'd be able to tell the difference.

Hey @three_easy_payments :

Some things to note: The Seas graphene mid-woofer has a heavily redesigned motor. If you read the Seas white paper they make most of the discussion about the corrosion reducing properties (a very important thing for Mg drivers!) and say very very little about graphene contributing to the sound.
