RDF i told you i will not let you weasel out of doing the math and i meant it. You made the claim many times that you could prove fancy power cords will fix ground loops because of the simple math E = IR. Now prove it.
Show the math!
Show the math!
Bigun - actually British mains plugs have brass pins, sometimes plated with non-tarnishing material. Brass isn't a great conductor (25-50% that of copper). Mains distribution boards where the services enter the house are often solid copper bus bars and connectors, but not individual mains plugs.
BS1363 plug tops used to have big rectungular solid brass pins.
But they brought in a new rule to help protect tiny fingers from touching the pins of a partially extracted plug top.
That change means we now have a much slimmer insulated pin for Live and Neutral and only the ends are the big chunky solid brass.

I will underline it this time:
I'm not encouraging anyone to pay a huge price for a power cord, but I always recommend TRIAL before buying when possible. 850 USD in not a small sum. My 40kg total weight DIY tube SET monoblocks cost this 😀
Everything on my audio system is tried and listened to before being bought. This is the way it should be. Yes, I know I am lucky to be a part of a friendly local audio community where we do exchange equipment for trial. I am lucky to have gained the trust of hi-fi manufacturing companies, where I get audio accessories home from them and try them before buying them.
Now I'm powering my system with DIY Neotech 3PS25 and DIY UP-OCC Neotech solid core cables with Valab carbon/rhodium connectors. Once I had the opportunity to not buy them and get my money back.... but I kept them. If they didn't make a difference to me, I still would've kept my cheap computer grade power cables until today.
The old 15A round pin mains plugs were the best but had no fusing. You can still get hold of them, but doubt that your home insurance company would be impressed if one caused a fire.
I have the smaller 5A, used for powering table lamps, spread around the periphery of the Lounge. One wall switch controls all the lamps.
The 6A MCB back at the distribution board protects the house from fire. I would not expect my insurance company to invalidate my house insurance because I have used a BS standard plug top and socket outlet.
And the placebo effect rides in on its black horse and saves the day for the golden power cord.
Do a listening test that controls the placebo effect, and just about all power cords sound the same - reason being that a well designed power supply (which are relatively common in these days) undoes most of the things that messy AC power tries to do.
And the horse lands on "Go" and we start all over again.
If you or someone else cannot trust his senses and suspects side psychological effects as undermining, there is nothing I can do about it.
I am curious. How many power cables have you swapped in your life? What were the audio systems you did on? What the cables were? I will gladly share my experience with this audio category, what about you?
I will be also pleased to learn your criteria of a well designed power supply. Because.. uh.. well, judging by your logic it seems many power supplies on many devices made by Philips, Arcam, Marrantz, Naim... and the list goes on; are so flawed. 😀
But I get surprised sometimes how naive and restricted most people are - trying to explain you how the universe works with high school knowledge. It reminds me how pathetic we humans are in reality.
That's absolutely correct. You cannot do anything about it, the psychological effects are inescapable, that's how your brain is wired. Otherwise, you'd be able to see through every magician's trick, every optical illusion, and be unable to have stereoscopic vision or sense images between stereo speakers.
If you're claiming that you're immune to it, that's ridiculous, unless you aren't human.
How can you be so sure, how my personal brain is wired and how my mind works? I consider it ridiculous to claim how the senses of another living being work.
And no, you cannot convince me with modern biological and psychological scientific "proofs" simply because science still develops. And this simply means - it isn't perfect. Period.
No, as long as we can keep people from finding out about human biases, we will likely have a convert.
Good, given that that the so-called undermining is scientifically proven.
I don't think you understand the true situation. By virtue of being human, you and I are programmed to hear false differences between power cables in a poorly designed comparison, which is your preference.
By false I mean that because of our biases and perceptual characteristics, we will very likely hear differences between two power cables that are identical, or the same power cable presented twice without our knowledge.
As long as you wish to continue to think as you do, please don't search for articles about unconscious bias and the like.
What logic is that?
It is true that high school physics is sufficient to explain why reasonably good power cords do not in fact sound different.
I think that one has to get into a second year psychology class to be taught about human bias.
You might be the creator of this realm we are living in. If so, I can believe you. 😀 I am sure you know very well how I am programmed and what is my life destiny.
Anyway, thank you for the vastly detailed answers to my questions. There is nothing more I wish to know,
Regards.
We take your claim to be human at face value.
That is a very naive view.
Science does not have to be perfect to work well and be useful in many ways. The laws of physics and engineering are imperfect and evolving, but we still seem to get a lot of good done with them.
If you lived like a full observant conservative Mennonite or Amish person your claims might be a little more believable, but then you wouldn't be posting on the web, now would you? ;-)
You're human. I can even be sure of how many chromosomes your cells have without testing them first. 😀
I suppose that in the past, many people seemed to get a lot of good moments of life, trying to think of planet Earth as a flat plane. Who could've thought that it could be round? Or square? He couldn't say such claims - he was a simply human affected by the placebo effect. Or maybe evil visions from unholy deeds.
The laws of physics were satisfactory back then. More than enough.
I am not sure when that was, because the scientific belief in a round earth seems to go back thousands of years.
https://en.wikipedia.org/wiki/Flat_Earth
"The idea of a spherical Earth appeared in Greek philosophy with Pythagoras (6th century BC), although most Pre-Socratics retained the flat Earth model. Aristotle accepted the spherical shape of the Earth on empirical grounds around 330 BC, and knowledge of the spherical Earth gradually began to spread beyond the Hellenistic world from then on."
If you truly want to live at the standard set by our knowledge of physics prior to the 6th century BC, be my guest. And, please throw your audio system and every other piece of technology away because they are based on scientific knowledge that was discovered since then.
I'm rather happy with the way that things have evolved since then. Without them I would already be dead several times.
Okay, so the human being "appeared" or "was created" on planet Earth some thousands of years ago. How many?
Thank you for enlightening my poor empty brain with such wonderful information from wikipedia. My old technological habits from the 6th century BC keep me from taking full advantage of the modern network system. 😀
My audio system is perfectly fine, but I suspect its power supply might be faulty, especially because I can distinguish sonic differences between power cords. 😉.
It's comes down to a matter of scale. It is a trivially small percentage of our DNA that defines our differences, we are in fact 99.9% genetically identical across the board. Anyone who claims they aren't susceptible to being easily fooled by their human senses (as all of us are) is in living in denial of that fact. Magicians earn their living by exploiting the frailty of human perception. Look up the McGurk Effect for a good example.
