Technical and scientific discussion of amps, cables and other topics.

Take it easy, my friend.

Hi.

We are not comparing the light speed with audio signal speed.

The speed of light travelling in vacuum is used as a reference speed vs that of a signal wave which passes across a conductor, e.g a wire or a bunch of wires (cable) in the realworld condition: inside insulation.

The materials (nowadays mostly plastic compounds) which are needed to provide safe operation of a wire or cable, delay the passage of any signal waves in various degree depending on their dielectric constants, which is made relative to light speed travelling in vacuum since day one. Please don't ask me why?

Ideally, a bare wire of good conductivity, e.g. Ag, copper, aluminum,
slows down the transfer of the signal waves least as there is no insulation adhered to the wire, only air. Air is next best wave conductor to vacuum.

Skin effect, which is not such a burning issue for audio frequencies, is out of topic of this discussion.

PS: this is what I consider genuine & proper way of inquiry, which I am more than happy to tell whatever I know of. But I would be pretty negative to those who came up with so called inquiries with undisclosed agenda behind them.
