Power Cords Snake Oil ??

“If it tests good and sounds bad it’s bad"

In other words, you didn't know how to test what you were hearing

"The truth is if we won the Nobel Prize for Physics you would then be saying: “Physics theory has nothing to do with great sound”. "

If you won the Nobel Prize, you would have gone through exactly the process I outlined. You would have published your work and proved to the satisfaction of others the correlations between sound and physical phenomena.

Obviously there are engineering, physics, and psychoacoustic phenomena behind what we hear. However demonstrating that something sounds one way or another is no proof of underlying physics. Like the majority of pc makers, you can sell your products based on sound, but if you are going to claim physical reasons that stand on any merit, you are going to have to provide evidence. Handwaving at theoretical physics is specious logic.

On white papers, there are about 80 years of work in audio that is firmly grounded in published measurement and engineering theory.

You are right there has been 80 years of "firmly published measurement and engineering theory";and look at the mess it has created.
Face it flex, you are a slave to the past. There are no words that will ever convince you of anything. That's not necessarily a bad thing, it just the way you view the world.
I think you sometimes forget that is a forum for the exchange of ideas, demands of scientific proof are better served in another setting.

Look at the mess it has created.... like acoustics, speaker design, electronics, digital processing, recording, microphone design, networks, midi. I think I'll stay lost in the past if that's true.

A forum for the discussion of ideas. String theory, superconductors... on Audiogon ??

Corona, no one seriously expects you to offer scientific proof, least of all here. Reread Zaikesman's posts if you need to grasp the issue. Discussion, real discussion, is fine.

Flex:
Is the one you are referring to?
"I think people basically *are* saying theoretical physics has nothing to do with great sound". I am not sure if he believes this or is saying that others do?
We believe it has everything to do with great sound that is why are so intrigued with "String Theory" because it is saying what we have experienced in the lab; there are no isolated events, all electrical phenomenon are interrelated.We are presently focusing on the relationship
between impedance and resonance. It does sounds strange!

IMHO & in my limited experience, I found that MOST powercords on the market is pure, unadulterated Snake Oil!! This has been confirmed to me by various audiophile friends many of whom use inexpensive Chris VenHaus Flavour X power cords after having tried several other expensive power cords.
I know that my pre (especially) & my power amp are sensitive to power cords. Searching for a power cord that has no sonic signature of its own within a reasonable price has been a tough assignment for me. I cannot afford an Elrod or an Electraglide or a BMI or any such $1000+ power cord! I'm presently using the ESP Essence cord & I find that it doesn't degrade the sonics of my pre & power. This I can tell you confidently. Is it "improving" the sound? No it isn't! I feel that it has practically zero sonic signature of its own.
Any time I hear or read that a power improves the sound, I'm leary of the claim. I believe that power cords cannot improve the sound; they can only change the tone i.e. colour the sound. All those believing that power cords improve the sound are listening to some form of distortion or the other that they perceive as "improvement". During the novelty period, it sounds diff. from what they are used to & it is mistakenly perceived as an improvement. Extended & critical listening reveals the flaws in the power cord & you see it for sale on Audiogon!
Electronics & Electricity will always be based on Physics (aleast on this planet!) & so equipment in these 2 realms will always have to honour these physics laws. Any improvements will have to be measureable. I'm convinced that if it's not measureable then one hasn't made any improvements or lateral changes or one doesn't know how to measure.
The money you can spend to lay dedicated lines to your wall outlets & to clean up the electricity coming to your mains from the grid will go far, far more than any power cord can. A power cord cannot fix what is broken (i.e. cruddy electric power) because it is a passive device. If you have a problem with your power, fix it at the source - that big breaker box located in your garage/basement.
If the power is clean, an inexpensive DIY power cable (VenHaus or Jon Risch type) should do just fine.
In audio, 95% of the stuff is TOTAL trash! Shifting thru this c*** takes a life time!
IMHO. YMMV.
