Silly conductors (here banana, mud) only add some resistance to a line, and do not make an audio difference stand out. iow: No need for high priced cables in general settings ever. (unless long distances, high power (so that adding resistance matter), or interference richt enviro (so shield your mud/banana)

Metals conduct beaus of delocalized electrons. Band theory is similar to thinking about molecular orbitals the concept from chem 1. When two atoms bond their atomic orbital mix and form molecular orbitals. But in band theory it is on a much larger scale 10^23 atoms or avagadros number. Insulators have big gaps in the connection band and semi conductors have small gaps in the connective bands.

I wonder what other electric words might prove useful here. I'm thinking explicitly about something like rhetoric's "conductive" character. Can rhetorical practice be thought through conduction?
