Life span of silver cables with cotton/air dielectric

Silver sulfide is a semiconductor with a band gap of 1.08 eV and thus would reduce the conductivity.

Party pooper.. it’s still pretty darn conductive.. Compared to spaghetti noodles, AY?  :-)

The whole point of using cotton as dielectric is to loosely cover the wire, so the main dielectric involved with the signal is air. Tight coverings exhibit dielectric absorption (DA), and teflon is the best solid, but not as good as air.

If you treat your cables with something, then that's the dielectric which a signal sees. If the dielectric is not air, you're defeating the purpose of a cloth dielectric.

But the issue with air is oxidisation of the conductors that is unseen and untreatable.
There was a time when most cables were sealed.  I even recall some manufacturers talking about a vaccuum.

Choices.....

Cables seem to bring out more strange threads than any other audio topic I know. Audio theater of the absurd I guess. That's my experience.
