Do powercords make a difference in sound?

Tbg,

Sounds like we agree on more than disagree.

I wouldn't compare the technical complexity of building a good PC or launching a successful space mission to that required of a power cord though. Very poor analogies!

Plus the space program is government funded therefore I would look there for innovation perhaps but not value.

Succesful commercial computer technologies tend to deliver both or do not survive.

High end wires are a boutique market with limited market. By their nature, they have to be expensive in order to survive. Only a select few will see value for whatever reason.

I might like to buy NASA mission grade surplus power cords if available for market value. Anybody know of such a thing? I think I have seen some power receptacles around this site that are of similar lineage.

Rwwear, I'll take that title "fanatic" as a complement. :)
If using several sets of cables in comparison is fanatical, then it applies. If facilitating dozens upon dozens of real world comparisons on the effects of cables (including comparison of silver vs. copper conductors) is fanatical, then it applies. :)

You may take it as you may. If you have compared dozens upon dozens of cables I submit your judgement will become convoluted very easily after just a few. Unless you have a number of folks doing blind listening without outside influence and being sure to take notes, it would be in the least very difficult to believe your claims by me. I'm not insulting your methods, they are just hearsay if using a scientific approach. I have heard so many claims that just don't hold up under scrutiny that I have to have irrefutable evidence before I will begin to believe unlikely statements such as being able to hear the difference between copper and silver power cables. I am not saying you can't. I am just very skeptical.

we live in a stochastic world. there is a probability that power cords make a difference.

in the broader scheme of things it doesn't matter if there is a disagreement on this subject. if a consumer believes and hears a difference, that is all that matters.oo

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. :)
