So you think wire conductors in cables are directional? Think again...

Here is a very relevant discussion among physicists about the directionality...the way signal and electrons should flow... based on conductor orientation. Some esoteric, high-end manufacturers say they listen to each conductor to see which way the signal should flow for the best audio quality.

Read this discussion. Will it make you rethink what you’re being told and sold?

Drive your car to work, then drive back. Your mpg is not the same both way because one way will have more uphill or downhill vs. the other way.

Same for electrons. They will expend different amount of energy differently directionally because the metal structure is not uniform.

At least that is the theory, but as far as if you could hear a difference, I don't know.  My old age hearing probably not good enough.

😀😂😂. Let’s just say this is a failed attempt to analogy

Here is a riddle for you guys.

Let's say you have a track from point A - to - B.  This track is not symmetric but have obstacles, uphill, down hill but everything is non-uniform.  May have more uphill or downhill depends on direction.

Case 1: You run from A to B then back to A.
Case 2: You run from B to A then back to B.

Will you expend the same amount of energy in both cases?

Ah, with a little bit of sleuthing, I found the article from the failed link where one of the engineers for Pink Floyd talks of how they built the recording studio on the Astoria. About 2/3 of the way down he goes into detail on how cables sound different one way over the other and that one is a better sounding way:

But hey, he's only a recording engineer working with Pink Floyd so what do they know?

All the best,

In all seriousness, to the OP: who cares. 
Step One: cables arrive

Step two: if they have arrows, place them according to arrows

Step three: done

Why is this so tough??

Unless of course you buy stupid shit Christmas “wire” from Home Depot, and are wondering why they don’t have any arrows on them. 
Which begs the question: why do YOU even have to worry about the directionally of the cable?
