Do powercords make a difference in sound?

Rwwear, skepticism is allowed.

Does a conductor's judgment become convoluted by hearing dozens of symphonies?

Does a circuit designer's judgment become convoluted by designing dozens of circuits?

Your argument that the more experience I have makes me less of a good judge of a phenomenon is weak.

I used to be every bit as skeptical, until I got over it (i.e. put my pride aside and actually compared).

BTW, I don't disagree that humans are horrible at double blind listening tests. However, I also insist that humans have phenomenal capacity to hear distinctions in sound/music. The rub is that I believe we have poor acoustic memory, which makes us poor at the testing. So, both are true; there are differences in sound which are easily heard, but we are poor at matching/identifying precisely sound snippets under tightly controlled conditions.

Based on studies about recall and the human mind (i.e. how poor people are at describing/recalling details to police what they saw as an eyewitness) I think I have pretty good ground to stand on for my position. :)

Your arguments for are much the same as my arguments against.

Mapman, I only alluded to NASA because of this trite phrase, not rocket science. I do know a guy that used to be in NASA who got surplus electrical wire, he prefers newer stuff. He assured me that current capacity was not their only concern.

Rwwear, yours is just one side of the constant argument about hearing differences. I just compared two identical cables other than one using long linear crystal copper and the other silver, anyone who could not hear the improvement of the silver should invest very little into reproducing music. But my only dispute with those holding your position is why you care that I don't hold with your position. You cannot provide proof that there are no better or worse pcs. Please don't tell me of the same/different 30 sec. comparisons, they are invalid measures of what people hear.
