K20 / Naim Naca 4 speaker cables are directional due to a burn in
process at the factory. If they are connected the other way around they
will adapt to that and after a couple of weeks they will sound the same
as before. There is a small audible difference.
If this is true
also for other cables there is no actual inherit preferred direction in
the cables
As I mentioned in previous post, the direction of metal cable is physically made and the sound doesn't change with the length of time. I heard sounds of many 40-50 years old metal wires in vintage gears melts like butter (in sound) in 1~2 minutes.

The current is alternating back and forth, not flowing downstream.
if the current flows better in one direction, it is restricted in the
other; therefore, directional wiring will absolutely make the sound
worse.
The current may be as you say, but the audio signal is not as you say. The audio signal goes in with positive wire and backs out with negative wire. In RCA IC, the negtive wire in correct direction is as important as the positive wire. The quality and thickness of wire in relationship between + and - wires change many things especially the speed of sound and rythm.
The audio signal is not flowing better in one direction but behaves differently in different directions. Typical sound of wrong direction wire is hot, grain, forward, no focus with wide sound stage (like out of phase). I know some super expensive speaker brands use all their wire opposite direction to make illusion of huge sound stage (out of phase).
