Directionality

I like Sean's possible explanation ... grounding only at one end. Seems plausible. However the concept of ANY directional cables in audio because of "crystal grain", winding of strands etc etc seems like total nonsense to me since they're all AC signals. I have always tried "directional" cables in both orientations and never heard the slightest bit of difference, so my ears tend to agree that it's nonsense.

Sean has it about right... that's called a "drain wire" in
most places...

You'd want to know which end is which in that case. Thus
"directionality."

Anyone who claims the metal wire or the plastic insulation
is "directional" is, uh, questionable.

In all cases the signal is AC and reverses direction on
each and every cycle, so there is no "direction" to the
signal - think of it as pulling on the rope that makes
up a clothesline with pulleys! Back and forth...

I was once told by a 30 years old cable manufacturer/designer, directionality a more of a marketing phenomenon than practical.

Ben Duncan in HFNRR found bulk wire to be directional and presented his measurements and findings......

Bob, in what issue is that ? Do they have a website ? Sean
