How Electricity Actually Works

Most obvious is why the dielectric, insulation, used to cover the bare conductor on ICs and speaker cables can effect the sound. Example Teflon vs cheap PVC. Going even deeper it may also explain why the geometry build of a cable can have an impact on the sound of a cable.

Can does not mean does in a fashion that can detected by human hearing. Everything can have an effect. Fortunately all these things are well understood by many, are easily modelled, and can be related directly back to electrical signal levels. That should be sufficient to make an accurate estimate if humans are able to detect the change.

Good reason to use coaxial cable.

Glad you mentioned coaxial cables. Great example for the discussion of this thread.

Here is how an AC signal travels in a coax cable. Note the signal does not flow in the center conductor. Note the signal does not travel back and forth from the source to the load. Rather it travels in one direction from the source to the load outside the center conductor through the insulation, dielectric.

Example: Power flow in a coaxial cable

Fortunately at the frequencies of concern for analog audio and our wire length field, signal propogation is not a concern though audiophiles get themselves worked up easily. For digital cables it is important but something figured out long ago.

I ordered a kite, some string, and a key off of Ebay last week.  

I'll let you know how it turns out.

Ha ha ha ha ha....

He is just so "deluded"!

Frequencies of concern?

How about, "Field interactions"? All of those pesky stray particles from simply wave diffraction. Particle Scatter from wave beaming crosstalk? Crosstalk from inductive winding archetypes. "Especially" with the common symmetry wire topologies so prevalent today and for those for absolutely no good reason. And so many, many more variables for affectation!

Correct "Signal Propagation" with integrity is ALWAYS a concern. "If it is not? You may have chosen the wrong hobby.

No matter the length, cross section or material mix used. The source signals integrity at endpoint is going to vary from its original form. Everything affects this. And always in a negative manner differing from the original form. And of course, "Every length, of every, single, (wire, bar or plate), in, on or even near, any and all parts, pieces and systems"? It turns out that ALL of that, just happens to be actual, "attenuating devices"! YUP, working, "antenna's"! Because if it is conductive, it has a polarity. If it has a polarity, it is broadcasting. If it is broadcasting, it is also receiving- "Noise/Distortions/Resonance" and more! And since all geometrically definable, "space" is not only surrounded by, but also just "Chock Full" of energy "in an insane amount of mass per unit of area". And mass equals what??

And that of course |IS| at it's core just another vibration. Which causes an oscillation....

I'll stop now, since I am sure everyone here see's where I am going with this...But why?

Ok, so you forgot about a variable or two. "So What" you say?

Any (one) variable listed above can be made to cause a terminal fault in any system. 

Now take them all. And account for them all in any given system. (As best you can). "This does not need to be perfect. Just your best work". In ANY given system.

Now;

Are you "Really" going to try to argue that there would not be any appreciable change in that systems functionality, if a full accounting and then following that a correction was applied?

That is all I am attempting to get you to see. But that should be enough!
