There's a flip side of the coin.
You collect some data and claim it is evidence for the shown phenomena. You haven't given evidence of correlation between the data and phenomena, but have already persuaded the crow it is the right data.
Now if the results of this data claim no audible difference (no existing phenomena) should exist, then the follower might believe so. And there will be no audible difference for him, he was already been biased to question anything as such difference.
Someone who believes only data and proof dictate what he hears is potentially prebiased to deny anything potentially existing outside his self-belief of correlation between the data and audibility.
You might discover marketing can be practiced in many colors.

Nobody talks about a single person here. To exclude phenomena like these, DBT's with as many unbiased subjects as possible need to be executed. This is the one and only scientific approach to approval.
Why should I squander money for anything with an uncertain outcome, especially despite of my knowledge that the (my own!) human hearing sense isn't a reliable measuring device?
Best regards!

If “audibility” relies on imagination and listener preconceptions (bias), then there is nothing relevant to be “heard”. Two different power cords actually “sound” the same, as they should. Claims about some mysterious difference, are not supported by any evidence.
There is none measurable difference at power supply output, with two different mains cords, so there must be something unknown involved, that nobody knows how to measure. Right.
It is the only straw that supporters of such claims can clutch on.
Actually improving amplifier power supply (which is measurable) will, in most cases, improve the sound.
Oh, I do believe that for you and others that can hear the difference, the effect is real. Perception is feeble and unreliable.
While listening, I find much easier to lift my spirits and perception with glass of wine. Less hassle than shuffling power, line and speaker cables and it improves the sound a lot. 🤣
Another more entertaining thread about power cables with undeniable proof that deaf 90 yr. nan with hearing aid clearly hears the difference when 25 mm2 power cable is being used:
Deaf can hear it
As for Covid, it is being said by some people that it was a new type of biological warfare.
Don't ask me if they were trying some unusual substances...
Some reputed researchers are now trying the mRNA method to develop medication for heart attacks, maybe they will develop a heart attack vaccine.
This wire business, power cords and speaker wires...maybe we should all have a button, along with the smilies, to point new posters at those, for them to read, before coming up with their theories...

25 square mm is the kind of wire rated for how many amps?
No need for an audio system, unless of course the man who started that thread can convince you to try.

I have a pair of 25 mm² cables to jump start my Ford diesel if I'll ever be in need to do so 😉.
Best regards!

Mine are 35mm2 🙂 But for jumpstarting this is hard to beat: https://www.telwin.com/en/prodotti/index.html?id=829566&lingua=E
And it doubles as a power bank for your audio gear!

Hi.
I started this thread (sorry again for bad English) and give some outcome after using new cable. Cable from original 1,5 mm2 to 2,5 mm2, silver coated. New quality silver plated copper plugs, silver plated copper ferrules. Total cost about 70 EUR.
Have listened it now almost 2 days and played many favourite recordings again. Reason to listen good music again is win already 🙂 Maybe it is from "self made excitement" or my old power cable was so bad, but feels that sound is better, more wide and dynamic.
I think it is point to try. If not better sound then you have one expensive power cabel for future diy electric component 🙂

Are you Markw4 under a different forum name? I'm asking because I couldn't help noticing the resemblance of your posts to his. 🤨
Indeed, the "burden of proof" is on the positive. You should be able to tell which power cord is powering your system solely by the sound, with someone else choosing which cord to use and plugging it in, and without you being able to see which one is being used. Being able to do this for more often than by chance (ssy, you're correct 8 out of 10 times) would be good evidence that you can tell the difference.
Definitely not. While Mark often discusses ears-only one-time-listening evaluations, he also knows how hearing can be fooled and how DBT's work.
AC power to many of our homes, travels part of the journey thru aluminum wires. Back in the 1970's many mistakes were made. Like an incorrect aluminum ally was used. And the wrong connector contact material.
Now the AC power companies use lots of aluminum wire. But it take special training, tools and connectors.
Same here in Germany. All conducters you see hanging from or between poles are made from aluminium. The simple reason: For a given conductivity, aluminium wire is much lighter (and cheaper) than copper. Buried cables, where weight doesn't account that much, are copper, though.

Not here.
OK, "here" in rural coastal Maine nothing can be underground, it's hard rock. But even in Florida or Illinois where sand or loam runs halfway to China anything over about 50 Amps is Aluminum. It is very hard to justify the extra $/Mho unless you need to retro-pack a tight conduit. Even then, heat often limits what "fits".
Do you happen to know how they do attachments? Welding?
For a time, houses were wired with aluminium wire. Connections to junction boxes, switches, and other wiring tended to go high-resistance, heat up, and eventually burst into flames. The U.S. Consumer Product Safety Commission (CPSC) reports that homes with aluminum wiring are 55 times more likely to have “fire hazard conditions” than homes wired with copper: https://www.familyhandyman.com/article/aluminum-wiring-can-be-hazardous-heres-what-to-do-about-it/

It is also necessary to have a scientifically plausible explanation for the phenomenon one is claiming to have observed.
If I claim that rocks drizzled with vinegar become weightless and float into the sky, but only in my house, and only when I'm the sole observer, and only when there is no video camera around; and I don't even have any scientifically plausible explanation for why vinegar makes rocks weightless; then why on earth would any rational human being take my claims seriously?

That's already been discussed in this thread.
The picture in the article shows a Bozo no-no. No wire nuts are allowed inside the service box. Plus the way a red and black wire have been tied together means a hack has been fiddling around in there. I'll bet there's other problems too.
IMPORTANT: I said wire nuts are allowed in the service box. Wire nuts ARE NOT allowed in the service box.
You probably have to change the breakers too. Look at the breaker type and you'll know.

Aluminum wires tend to corrode galvanically, if copper is bonded directly.
Brass or steel as the intermediate material works.
Corrosion is also an issue.
Here we have evolved the alloys to be used, and we do not have freezing conditions.
Aluminum terminations with aluminum lugs have been reliable for many years. You must use proper quality wire, and securely crimp lugs.
Also 50A connections mean that a trained person with proper tools should be working, not the handyman (or pretender handyman).
Our flat in Delhi had aluminum wires, which we replaced with copper as it was brittle.
But really, no fire issues, it is quite common here as the service wire from pole to meter, and on to in point of breaker.
My house has had it for years.
The only issues were rain caused corrosion between open conductor on pole and where the drop wire (service wire) were joined, that has been resolved by using special clamps.
Your weather and materials may be an issue, which caused your comments...
