Geoff, above and in many discussions you have stated that the wire drawing process impacts the wire crystal structure making it inherently directional.
Assuming it does, I think the question is does this impacted crystal structure in some way make an audible sound difference when the wire is inserted into a system in one direction or the other?
One might think that in order for it to make a difference, the signal, power, whatever, would need to flow differently depending on the direction of the crystal structure. This would imply that if the wire was inserted incorrectly from a directionality viewpoint, the crystals are impeding, or in my obviously non scientific terms ,snagging and impeding the signal or power compared to the correct direction and this somehow impacts the sound.
