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

RE: Cable shootout... Are all audio cables the same?

“So far I have not heard you say that the audio signal itself, the electromagnetic wave, the one that travels down the cable at near light speed, is alternating back and forth along the cable (as claimed by naysayers of wire directionality)”

Well that is true, I have not said that.
Perhaps I can clarify this further but it will involve some electronic engineering.

It is current alone that produces the H or magnetic induction resulting in a magnetic field B, it is Voltage across a load or resistance which causes current to flow.

The signal Voltage propagates at the cables propagation velocity and is set by the cables series inductance and parallel capacitance and can vary from near light speed to as slow as near half light speed.

It sounds like your confusion is based on the “signal” being somehow different than the Voltage which is the signal.

If interested, the next edition of “Handbook for Sound Engineers” being printed now has a chapter on loudspeakers which goes into this exact thing in some detail.

“So, whaddya think, is the audio signal traveling down the cable in one direction only?”

Again some confusion, YOU are the one who thinks “the signal” travels one way better than the other, my point is “the signal” is a Voltage magnitude referenced AC signal which spends half the time going one way and half the other.
