People are free to think anyway they want. The importance is backing up the claim with evidence. Do you have any?
Before continuing further, my best advice would be for the person to try two different power cords on his system, but built from different types of wires. Usually most audible different are fine stranded vs solid core. They don't have to be expensive, just regular hardware store types. Usually components near the source (vynil player, DAC) are the most sensitive. It's also great to have one or more unbiased people listening to your and listen for long periods of time with each cord, for example one week per cord. Do some swaps, listen for a month.
If one does find differences, then it's worth continuing futher.
I did once share blind tests of power cords in a facebook audio group and never bothered since then. I keep the evidence for myself. Is it worth sharing from a practical point of view?
How do you control the visual bias of seeing / knowing which cord is being used?
How do you keep the aural memory fresh for that long? We (humans) only have a few seconds before it fades away too much to be useful for objective comparison.
Of course it is. Without it, the claim has no validity. It's like someone claiming that he can fly like birds by flapping his arms fast. Wouldn't you like to see him reveal the supporting evidence? If not, it's a laughable claim, no?
1. The unbiased people are not aware/being told of any changes. They listen to the system ambiently.
2. It might surprise you some people can have very long aural memory.
Of course. A claim however can make some people want to try out for themselves and search for their own proof. I am not trying to convince people of right or wrong here, but sharing part of my years of experience.
Again with years of experience and testing out people. Experienced listeners can become quite familiar with timbres of all kinds of components, the same being valid for musical instruments.
I have never seen a solid core power cord.
Even the outdoor pump for my air-conditioner is wired in stranded. Yes, my hot-water heater and my well-pump are wired in solid.
Indeed!
Now I want some of those drugs!
I want to see lightwaves dancing in my mind.
OK, so you are just sharing your anecdotal perception. Got it. Then you shouldn't have written, "I keep the evidence for myself." because you don't have any.
How long is our aural memory span in numbers? How was the test set up? I'm asking because your results don't seem to be in alignment with scientific research done by other/s before.
😆 I've recently heard about the resurgence of certain mushroom...
You just KNOW that a thread about wire now 4 pages/72 posts long is one of those endless debates.
...........That got tired by the first page.

1. Why not? Besides I do claim I have an evidence for myself, but how would you deny this? Can you prove me wrong that I do not have evidence for myself?
2. Don't know about numbers, neither I cannot know how one puts auditory memory into data. What I know is that unbiased people can detect changes in power cords and on top of that, they can describe the nuances they hear.
Let me tell you....
My aural memory goes way back, back to 645 B.C.
Back to a time when polka dots made of cotton candy floated through space, and when they occasionally bumped into one another, they made a cute little giggle-sound.
1. You've supported your claim with another claim. That's all you've done so far.
2. In case it's lost in translation (perhaps English isn't your first language), aural memory span in numbers means how long we can memorize in duration. How many seconds, minutes, hours, days, weeks...etc. Same kind of question as "How long is your power cord in numbers?" You can answer in centimeters, meters, feet... etc.
In this case, that's what you believe. You haven't done any objective comparison to draw any objective results. All you've got is anecdotal perception, which you are free to have but it doesn't qualify as evidence.
Different parts of aural memory persist for a lifetime. Proof you say? Sure, you recognize peoples voices don’t you?
Back to the topic, if the power cable can carry the needed current without heating up and the contacts are not corroded you are in good shape. Putting an expensive power cord on a long run of 10 or 12 gauge solid wire does zero except costing too much.

Which part of aural memory did you think I was referring to when you wrote that question? Hint, post #64.
If that doesn't get through you, then answer this, you record the voices of those whom you recognize, then play back through 2 electronic audio systems, one with power cord x and the other with power cord y, then listen at matched level but one at a time separated by a week, do you think your aural memory is fresh enough to be useful for telling the difference if any?
