Dumbest cable question

I suppose there are dumb questions and dumb answers. Turn around an average fuse in a decent system and you will hear the difference

Some wire is directional! Easily proven using your ears.

More importantly, try it yourself. Don't ask, tell.

I believe zero about conductors being directional, but in the case of shielded cables you want the shield connected at the source but not the destination, which is the reason for the arrows.  In most systems though shielding is barely necessary so this may not even matter.

This is very far from the dumbest question I’ve seen here. Very far. I don’t have an answer for you, but Chris Sommivigo (stereovox/black cat cables) believes that speaker cables carry an AC signal, which is constantly varying back and forth 60 times per second, so no matter which way you orient cables, the signal flow will always be “wrong” in one direction. I don’t know if he’s correct, but many here claim to hear differences when the cable direction is reversed. It certainly won’t hurt the cables to reverse them. 

Nothing wrong in rotation, but whatever you do let it settle for some time.

Listen and evaluate.
