You've been following the wrong sheep all these years. No offense, but you are very confused.

What's next, the sky is blue? Where does Maxwell discuss the audio signals? You seem to have the ridiculous idea that the energy that is outside the metal conductor, I.e., the e nd b fields, is unrelated to the physical and electrical properties of the *conductor* Hellooo!!Two can play that game. Einstein wrote e=mc^2 therefore I win the debate.

More names.15 years, you still don't get it.
@herman tried his best to explain to you how electricity actually works 15 years ago, and several years after that. The Late @almarg tried his best to explain how electrical energy travels from a source to the load. It ain't through the wires... @kijanki tried his best for several years. I provided countless Web links of the writing of men like Ralph Morrison. Nope you said Morrison had it wrong too.So up until you, no longer posted on Audiogon, I would tell you the signal energy travels in the form of an EM, electromagnetic, wave from the source to the load in one direction at near the speed,(50% to 90%), of light.
Because of the low frequencies wires are needed to guide the EM wave in the spaces between the conductors.
The source creates the energy and provides the voltage potential that creates the electric field around the conductors. That in turn causes the electrons, electric charges, to move in the wire, slower than cold maple syrup, ( see drift Velocity). The movement of electric charge creates the magnetic fields around the wires. Combined, they form the signal energy EM wave.
Using a 120V 60 Hz Ac generator for the source and a light bulb as the connected load.
The electric charge, vibrates, oscillates, 60 times a second in the wire. It hardly moves at all in the wire. Your theory, unless you have changed it, the electric charges carry the signal. Again, Google electric charge drift Velocity. Using your theory when you flip the light switch on it's going to take an awful long time before the bulb lights.It's the EM energy wave that travels at 50% to 90% the speed of light that lights the bulb. Flip the switch on, light bulb lights instantly. Electrical energy is transferred from the source to the filament of the bulb. Not the current through the filament in the bulb.
Current leaves the source and returns to the source. Current is not consumed... Energy is transferred from the source and consumed, (transferred to another form of energy), by the load. Energy does not return to the source.
"Conductors end up directing energy flow - not carrying the energy."
An audio signal does not return to the source.Signal energy EM wave from the output of an amplifier to a speaker voice coil.
"It has nothing to do with what we commonly call "current", which most visualize as electrons flowing back and forth. It simply doesn't work that way. There is an electromagnetic wave that transfers energy to the coil of the speaker. If applied to a resistor it creates heat. If applied to an inductor (coil) it creates a constantly changing magnetic field which pushes and pulls against a fixed magnet creating motion."
A better way to explain it.
"The speaker does not operate by electrons flowing back and forth, as is the common visual analogy for "current". Instead, a speaker uses an electromagnetic wave to transfer energy. This wave, when applied to a coil (inductor), creates a constantly changing magnetic field. This magnetic field interacts with a fixed magnet, causing the coil and the attached speaker cone to move, producing sound. In contrast, when applied to a resistor, the electromagnetic wave generates heat due to the resistance to the flow of electric charge."

This is the first audio cable designer, (holds many U.S. Patients) that talks about signal EM energy waves. (At least the only one I have read about.)
Galen Gareis explains it more eloquently than I could ever do...

1.0 ELECTROMAGNETIC WAVE PROPAGATION"The issue - What do we actually LISTEN to on a cable? What is the "root" reason to be for a cable?
Cables exist to move the "signal" from one place to another, but few really consider WHAT that signal is. The signal we "use" is the electromagnetic wave moving down the cable at the group velocity of propagation of the dielectric."

The "audio signal " is what moves the speaker diaphragm back and forth, nothing more nothing less, the other stuff you can forget about. It's the signal because it tells the diaphragm to move one way or the other. That "signaling" occurs in real-time, not at near light speed as you've been conned into believing. Since the audio circuit is AC the electrons, the charge carriers, the current being the total number of electrons per unit time. The electrons move back and forth, in tune with the speaker motion, since they produce the speaker motion. The frequency of this electron back and forth motion is equal to the instantaneous audio frequency. Electrons as everyone knows by now don't move very far at one time. On the order of millionth of an inch. OK, that part you didn't know. Speed has nothing to do with it.People believe things because they've been conditioned to believe them. - Audiophile axiom
