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

Engineering wise, conductor signal direction makes no sense, especially since we are talking about AC signals that change directions anyway.

However, before anyone says no.  (Which I will quickly as an Electronics/Electrical Engineer), the real test is to hook it up to a signal analyzer, and see if there is a difference.  Then, play a song with the cable in question.  Then reverse the cable and place the same song changing absolutely nothing else.

Blind is better.  If the people in the room and yourself for that matter hear differences, well, there you are.

For Engineers this is a non issue as it doesn't impact what they are designing and using cables for in the first place.  For Audiophiles on the other hand, it is more perceived.

Science is not about perception, it is about repeatable environment and test, to repeat something under the same situation/circumstances/environment.  It is isn't repeatable, it isn't science.  it's magic.

But, I won't say no. I will say, show me.

No.

Also, these things are measurable by science.

It is just not worth it (Read cost effective) to spend considerable time and expense on cable directional issues for audio signals. For power transmission or distribution circuits from power systems, then cable science makes sense to pursue. in order to keep high voltage  transmission line losses low.

also, for audio or power cord cables, it comes down to:
1.  Impedance
2.  Capacitance (included in impedance) loading
3.  inductance loading (included in impedance)
4.  Resistance (included in impedance)
5.  Skin effect (maybe)
6.  voltage capability
7.  Current capability
8.  Costs to design/construct

Unless there is serious scientific reason why, (or serious money involved),Engineers will not be concerned with low level cable signal direction.
