Power Cables diminishing returns


I'm thinking of upgrading my PCs, but am wondering what the sweat spot is as far as price. The price point after which, you see diminishing returns. for example a $1000 is certainly not twice as good as a $500 cable.

In double blind testing audio reviewers could not tell the difference between PC's that were $50 and those at 8K. Several such studies have been conducted --- all with the same results. This would suggest that the "perceived" differences that a cable owner hears is likely rationalization for paying what they paid (or some other psychological reason for the perceived differences). Perhaps there are "real" differences, albeit subtle, in certain systems with fairly unusual system synergies --- but in controlled settings, no one has been able to double-blind distinguish between PC's.

That said, interconnects and speaker cabling is indeed quite a different story --- there the differences can be fairly large. But power cords no. I talked recently to Frank Van Alstine on power cords and he laughed at the notion that people spend over $50-70 for a PC... said, from an engineering standpoint, that anything more is a waste of $.
It's tiresome listening to the Flat Earth Society explain what a human being hears in terms of math and Newtonian psychics.
A human is a miracle of integrated being that hears with its ears, eyes, brain, CNS ,memory, conscious cells in its stomach and many other ways we know nothing about. Not to mention its soul. Of course if you can't see something you have trouble discerning, as you do with seeing if you can't hear.
Conductors in their 80's who can't hear a 5kz tone, routinely correct players playing 10hz tones!

We humans are several orders of magnitude beyond explanation
by Quantum means, much less by some fool running a double-blind "test".

One of them is when you leave the mystical out of the musical equation I don't know what answer you may get, but I do know it will be wrong.
But Schubert, if how this stuff works can't be technically explained, or can only be partially explained, upon what principles and upon what basis do the designers of the power cords design them?

The likely answer, as I see it: Upon some combination of trial and error, using a relatively limited number of systems; pet theories, whose applicability across a wide variety of systems is unproven; and, perhaps most significantly in the case of expensive power cords, by overkilling every parameter that the designer considers to possibly be relevant. With the degree of overkill increasing as the price of the cord increases.

Implicit in my earlier post in this thread is the thought that the system and component dependency of those effects that ARE technically explainable, as well as the fact that those particular benefits are obtainable at relatively low cost, can be expected to loosen the correlation between power cord performance and power cord price. Each of the three approaches to power cord design and development that are listed in the preceding paragraph can be expected to further loosen that correlation.

it is not easily heard and they the listeners were not stone cooled deaf as you said. They the listeners listened used a double blind test and could not hear a difference. That Mr. Schubert is the only proper way anyone can evaluate and determine if there is a difference. I myself am sick and tired of the self righteous so called golden eared. Who claim that it is so easy to tell the difference between different audio components. When in fact many blind studies have proven just the opposite. It is more tiresome to hear your rant Mr. Schubert on how gifted you are and blessed. That I should make a special visit to Lourdes to correct my deficiency in the hearing department. I can guarantee that neither my hearing or my common sense are wrong. And I can defiantly say that in a double blind test neither you or anyone else can hear any difference with any pc Mr.Schubert.
