Linn 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."
HiFi Tuning of all people used to state that (their) fuses were not directional, that they break correctly no matter which direction they were inserted. Of course HIFi Tuning now admits they were incorrect and that their fuses are directional. Hence the diode symbol with the uh, arrow on their fuses today. Synergistic Reseach, in a similar vein, used to state that their fuses that were subject to one million volts ("quantum tunneling") would be not be directional, you know, due to the million volts. Now everyone and his brother knows that Synergistic Research fuses are dirctional, one assumes even Synergistic Research.
