connect 2 different wire gauge to pos and neg speaker terminal

@almarg One of the best posts I have ever read on audiogon.  Your explanation seems logical, takes some of the mystery out of cable theory, and "almost" makes me want to fiddle with cable design.  I do appreciate that it is more complex than it seems.

Great post Al.

If the audio signal travels through the *dielectric* and not (rpt not) through the metal conductor I suppose we can throw out the whole skin effect idea, which says most audio frequencies travel *inside* the metal conductor at some depth, with only very high frequencies, perhaps above "audio frequencies," traveling near the surface, I.e., skin. How can audio frequencies travel inside the conductor when the audio signal - the electromagnetic wave - travels outside the conductor?

Al - thanks for the informative response

However, I need your help again...

Let’s take the IC connecting two components as an example...
- the signal conductor has an AC signal on it
- the neutral conductor is connected to the neutral sides of each component

On well designed components the neutral side of the circuit should always be at zero vaults - especially if grounded

If both components are well designed, then the neutral sides of the their respective circuits would be at zero volts,

Therefore, the neutral conductor of the IC should also be at zero volts - yes?

What exactly am I missing here ?

Sorry for being a pain and thanks in advance
