Cable Current Flow Direction

just to complicate things, w/some cable manufacturers, directionality refers to where the shielding is connected, if at all.

If the cable contains multiple conductors (signal & ground) and a shield, the shield is connected to ground on the sending end only. On the receiving end, shield remains open with no connection. Arrows will point in the direction of signal flow toward the receiving component.

With coax type cable, I have no idea why there would be any directionally,
other than “audio fashion.” Company ABC adds arrows to their cables
because Company XYZ has them.

I doubt that I could actually ever hear the difference. I have some cables with a small band or label at one end. Is there a general industry standard as to whether the banded end is the source or the destination? Or, does it vary according to supplier, as some responders have suggested?
(I do have some "arrowed" cables and the supplier of these told me that the arrow indicates the direction of the flow. They also told me that at one end the sheild is grounded, but not at the other end.)
In all cases, I am talking about RCA cables rather than XLR.
Thanks again!

Thx, Tls49, that's what I was trying to say in my non-technically educated way; however

Arrows will point in the direction of signal flow toward the receiving component.

not sure that is true. I believe that some folks believe that all grounding should be oriented toward one component, which, it seems to me is most logically, the pre-amp. However, I doubt that there is any universally accepted standard, so I think that if the OP thinks that it's important, he or she should ask the cable manufacturer.
