To verify that a difference exists, in your cable, you need an old Tuner with a meter. Don't laugh, this is a very sensitive test instrument, just follow the steps below:
First of all, I have to thank you for such an interesting example! No laughing at all, because I definitely know that the direction of the wire used as the radio antenna is just as important as the direction of the wire in the signal chain. This can be easily checked on any receiver, or better on an old tube radio, where the difference is more obvious. You can even see it on the TV if you use an old-style aerial antenna instead of a modern digital cable signal. The difference here will be noticed not only by ear, but also by eye, in case you care the difference between the image of old movies and modern digital ones.
But unfortunately this example can not prove the wire direction audibility in signal chain. The antenna picks up the RF signal, the meter also responds to the fluctuations of RF signal together with the level of rectified audible signal. There are a lot of extraneous interference in the RF signal, which change both in time and from the slightest deviation of the antenna from the initial position, this is the weak point of the receiver meter based proof.
Wires definitely has preferable direction, but each attempt to explain it by means of difference in electricity signal is easily challenged if you know the ropes of radio engineering. I still cant imagine how wire direction can be explained withing physics.
With respect.
