Does that help answer your question?
From the position of "cables don't make a difference", that does answer the question, unfortunately, I'm of the other frame of mind.
Conductivity is definitely consistent in all of my cables, geometry determines capacitance and inductance and material determines resistance. These are all measurable things and whether they can qualify as affecting sound is another debate altogether.
As for switching out 5 or more cables, well, what if I think they are all a little different (some very different), and since all cables are different, which one is transparent?
