Another case for the "directionality" people, is that even if both ends
are not being bias differently and the current is truely AC, on the driving
terminal in this case is the amp, the voltage is always slightly higher
than the other end since there is always some resistive losses in the cable.
Think of the cable as a simple voltage divider driving the speakers as a load. You have input voltage and output voltage. Obviously for a voltage divider, the output voltage is always smaller than the input voltage. So at least in this case, you have "directionality" because the one terminal is subjected to one voltage and another terminal is subjected to another voltage.
What I said above is just theoretical. In practical situation, I have to
admit it would be different to hear the difference unless I guess have
have a really exceptional system with top notch transparency.
