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

There used to be a working link I've used in past discussions on cable directionality and it's not coming up anymore.
(http://www.tubemastering.com/philtaylor.pdf )It had to do with Pink Floyd and the building of a studio on the Astoria (David Gilmore's house boat), a boat they used to record on. In between sessions, they swapped cable directions and easily heard the differences, preferring one way over the other.

The best I can do right now was to find an article that doesn't go into it in such depth but speaks to the differences in cabling that can be heard.

Scroll down to the "Grounding on Water" section in grey.

There's also this from Tony Farinella who makes the cables that David Gilmore uses: http://sparebricks.fika.org/sbzine28/ggg.html
There is a section where he discusses cable directionality.

Let's see... another non working link to TapeOp about the house boat and cable directionality....can't find anything else for the moment.

All the best,

What/who are RF Folks?

I can only think of "radio frequency" off the top of my head.

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?
