Stranded wire is not necessarily directional, only if all the strands are controlled during manufacture to be in the same direction. Without knowing for sure I’d guess the strands probably are all in the same direction. But if they were in random directions, not all the same, that would certainly explanation n why there’s no difference in direction. Audioquest controls all their cables and cords for directionality, including stranded cables and cords. I suspect Duelund is unaware of wire directionality.
