1. Of course, not trying to bring proof of anything in public here, again just sharing personal findings and it's completely OK to be viewed and questioned by others as just claims. Hope you're not insisting to say it is against forum rules or anything.
2. Months for some, even years for others. The voice recognition example is a good one. If the same system recreates two different nuances of voices, why shouldn't the auditory memory store them for long periods of time?
Coincidentally I have a version of this Knipex crimping tool that is destructive when crimping. It looks the same but crimps some pressure points 1 mm from eachother making the ferrule mechanically weak.
Practically no one that makes quality power cables will put stranded wire under a screw without using a cable ferrule as that is simply bad practice. The cable ferrules make contact to many of the strands just like the strands make contact to each other. The cable ferrule itself makes contact already at various places in the contact pin when the screw is not turned yet. When the screw is turned contact is made by the ferrule to the contact pin at various places and via the screw. The screw causes a dent by bending the cable ferrule a little causing the ferrule to have kind of retention mechanism. What else could one wish?
The tin/lead solder on stranded wire won't make a monolithic mass of copper! This soldering stranded wire amateur/DIY practice is exactly what is taught not to do to young techs. Tin/lead solder is just not meant to be under pressure under a screw.

I simply asked about the details of your process. I guess for some reason you don't want that to be known.
That's your belief. I don't think you understood which aural memory I've been referring to.
As for "same system recreates two different nuances of voices", it's 2 different systems recreate 1 voice, one with power cord x, the other with power cord y (2 there), to find out if there is audible difference from the same voice recording.
The best you can do from your outlet to your Amp is to replace your outlet with a commercial grade outlet, not pricey they go for about 3 times the cost of a residential grade outlet. Just get a length of nice Belden 12 gauge "power tool ' cable, terminate it with a commercial grade plug made for power tools, find a good IEC plug. Up to your outlet your home is full of galvanic contacts in the branch circuit and all kinds of low grade copper, and your breakers are another contact. And your neutral is probably being shared by two other nearby rooms. And the mains line into your home could have been there 50 years. Thinking that a power cord can correct all that goes on previous to your outlet is denial. One worthwhile effort is to pull a dedicated 20A outlet on a dedicated breaker, this is easy if your home uses steel conduit.

Do you have any hypothesis that would help explain why they sound different?
Suppose we make a stranded cable straight from the fusebox (the same length as the internal solid wiring and your DIY solid-wire cable) and compare it with the solid-wire power path, would the difference between these paths be even greater than the 6-feet of either stranded or solid cable from the outlet?
For a dedicated outlet the main goal is you'd want the get all 3 wires "home-runed" back to the breaker panel, IOW don't tap off of any other nearby junction boxes. This way there will be 0V potential between your neutral and safety ground preventing hum loops. I didn't know "audio grade Romex" was a thing, sounds like snake oil, just run 12 AWG Romex, 20A breaker and a 20A commercial or hospital grade outlet. Bond the safety ground in the breaker box directly to the safety gnd bus, bond the hot to the breaker, bond the neutral directly to the neutral bus. Now at least you'll know inside the home you did the best you could, prior to that you have no control over that belongs to the electric company.
My main hypothesis is acoustic vibrations. Check post 59.
It's a good question. My primary guess, the farther away from the system acoustics the cables are, the less audible they will be, especially power cables within a concrete wall. So I wouldn't worry about the internal wiring much. I find the most audible difference lies in the plugs (main plugs. IEC plug, sockets), where the sensitivity of audibility is more significant than modifying for eg, the mid point of the cable. Another hypothesis, is the better mechanically coupled the plug is to an acoustically ringing lightweight surface, such as a thin cover or PCB, the more its influence and its cable is on the sound.
Yes, you can practice directly on your ringing surface directly instead of playing with cables. I've been practicing this research for three years and never changed my cables since.
The material of the body seems as important as the metal contacts and it can be modified by the addition of different materials and mass.
Seriously, Psilocybin has most recently been discussed as a promising drug against CoVID

You can’t hear a difference if there is no difference. As long as cord x and y both provide the needed current there will be no difference in the sound of the amp. This is about power cords isn’t it?
Obviously, but some posters confuse the perception with audibility. Audible difference isn't required to perceive a difference. Sometimes just being told that there is a difference triggers a perception of difference.
I think you will find a discussion somewhere about silver plated vs. plain copper wires for power cords and speaker cables.
Simply put, use a cord rated about 50% higher than the expected current it is expected to carry, and use good quality materials and construction.
To me your perceived audibility of a cord, because it is near the unit, excludes the damping from the insulation coating the wires, which will absorb and distort the sound reaching the conductors.
That is bordering on OCD.
Some free advice: find something else to obsess about, OCD people need something to worry about, or they get disturbed, like a smoker needing his nicotine fix. It is an addiction of sorts.
Or you could do research on the subject of coated power supply wire distorting the 50 or 60Hz signal from outlet to unit when subjected to audio frequency signals from the audio equipment is it supplying.
You can compare different construction, insulation types, single or double coated, number of strands, and so on.
I insist your results should be repeatable with similar equipment anywhere in the world.
It will keep you occupied.

Not seeing anything wrong with is, as it is part of my research. I look at this as studying and knowledge.
In summary, denying a phenomena or looking for a simpler answer is not a proof of inexistence. You cannot give proof to prove me wrong either, you just shoot random claims simply looking for bias and excuse to deny something you don't believe in, but you also lack the evidence. Simultaneously, the brain can be biased to deny anything it percepts the same way it could to accept something that doesn't existing.
It's an never ending debate without useful benefits, but what keeps me sharing this knowledge is the people who are still interested in this domain and potentially reading the topic.
Isn't to show evidence on someone who shouts out rather strange claims that are very contradictuous to anything that is proven scientifically, rather than on someone who argues scientifically based?
Best regards!
Best regards!
Why would you understand it as shouting in the first place? In the audio world a lot is shared between the enthusiasts in the form of empirical listening and experience with equipment. Not every reader needs scientific proof of some sort.
This exactly is the reason why fooling the gullibles is that extremely successful.
