Which end is which?

Braided shielding is connected at both ends. Therefore there is no audible or measurable difference directionally at either end. Jasonbourne71 is vindicated !! Ignorance is bliss….Not !
Gullibility is alive and well….Sadly !

The red end wih an arrow indicates that it's a gozinta. As in it gozinta the downstream equipment. The other end is the gozouta, where the volts gozouta the upstream device.

Whether it matters or not is subject of hot debate between the earnestly misguided and the quacking hucksters on one side, and the physical realists on the other. Cables can matter, just usually not for the reasons and quasi-theories promulgated, and not as much as claimed.

...if a cable was directional, I'd rate it next to a subtle form of eq....
Then I'd wonder why someone would want that....

Anyway, far out and not long ago in sidereal time, there were those that claimed God spoke to them through their speakers.

I've always defaulted to giving another 'space', when it comes to belief....

...unless, I'm pissed....
