Many new electrical facts have been established in the past 100 years, that support audible differences, between various cables, fuses, etc.
I couldn't find anything like, "Updated Electrical Theory For Idiots", but- did manage to find something resembling a cartoon, that even a child could follow. It neither mentions AC/sinusoidal waves in wires, nor does it go into the photon propagation of electromagnetic waves. It does, however, emphasize/demonstrate how Electrical Theory has progressed, since the 1800s:

These next two presuppose a certain amount of knowledge, in the field of modern Electrical Theory. Click, "more" in the first link's third answer, to get its entirety. Note how it mentions the OLD, "... commonly held misconception that the flow of electricity through a wire resembles a tube filled with ping pong balls...", to which the Denyin'tologists fervently adhere:

It's an established (measured) fact that an electromagnetic wave's propagation and speed, are dependent on the materials, of which the transmission line (cable) are made (ie: Dielectric Constant/permittivity). The better (lower) the Dielectric Constant the better the flow and the longer it takes for that material to become polarized. One reason anything that comprises an RLC circuit (ie: capacitors, cables, PC boards), takes time to, "form", or, "break/burn-in".*
*Some things that make the Denyin'tologists apoplectic:

The conductor acts as a waveguide:

Even the most inane (regarding the Sciences) must admit; braiding and twisting wires eliminates/reduces EMI interference.
That must lend credence to various cable geometries.
That better dielectrics enhance the propagation of electromagnetic waves (ie: your music signal), lends the same credence to choosing cables with better materials (ie: Polypropylene, Teflon, air, etc).
Of course: anything the Church of Denyin'tology's popes can't fathom, they'll summarily dismiss.
