Power cable from wall socket to power strip

@simna-

     I found so many different and contradictory answers and opinions so I wrote these questions that made some here mad at me.
                                        I’m sorry for that.

                                         You opened the thread with:

               I don’t want a discussion with ”non believers”.

                              Let the Cargo Cult go build another runway!

                                                    Who cares?

                                                 Happy listening!

@simna 

 How can the power cable from the wall outlet to a power conditioner have any importance?
The power has traveled through miles of ”ordinary cable” to my wall outlet, so how can this last bit to the power conditioner, that is supposed to clean the dirty power, have any impact on the sound?

       Did you bother to read anything I posted?

       Bother to LOOK into any of the SCIENCE involved/mentioned?

    Virtually every modern convenience, computer, electronic medical, listening or communication device you've been enjoying, invented since the late 1900's, resulted from the study of just those (mentioned in my posts) phenomena.

        While what I've posted are my postulations (far as PCs); they are based on some VERY SOLID SCIENCE (Physics/QED).

@simna-

                      What I would recommend, far as manufacturers:

  "I figure the best way is to borrow some high end power cords and compare them with an ordinary power cord."

 'And here come the cable deniers, lol. Saving the world... '

 'So old. So obnoxious. '

        Candyman, Bloody Mary, Beetlejuice, and the local Cargo Cult... WELL: those last ones can't even wait for their names to be spoken three times any longer: CAN THEY(snicker)?

                                  Let 'em go build another runway!

                                              Happy listening!

                                     A rewind:

rodman99999 5,456 posts 03-31-2022 at 12:13am    @holmz-       Bear with me a minute, in my folly, far as a possibility on why a power cord might make a difference.       Based on some of the theories on how electricity works, simplified:       The conductor acts as a waveguide for the signal/voltage.       Within the conductor: when excited by an AC current, electrons oscillate, generating photons/electromagnetic waves that travel, always from the source, to the load.        Keep in mind: all signals (ie: music, AC) are sinusoidal  waves        Those photons/electromagnetic waves travel through and outside the dielectric, which (according to it's permittivity/Poynting vectors) will have various effects on those waves.    One of the most obvious, is the dielectric's effect on the speed of the signal.       The better designers of printed circuit boards, even take the above into account, when choosing materials for their products.        I posted a link on the first page, that included data on the manufacture of semiconductor chips and what was observed when materials were cryo'd, during process.     Short version: better contact/lowered resistance between layers.           Under the scanning microscope: much smoother surfaces observed.        I would hope, by now, it's a given that various cable constructions, twists, braids, etc, can make for a cleaner transmission of signals (ie: Litz, etc).                     Just seems to me (a hypothesis): given the above (some theories and some things established/measured/proven), it's not a big stretch to believe a power cord, built of the best conductor (Ohno CC silver), wrapped in a very low dielectric coefficient dielectric (ie: Teflon), cryo'd for the smoothest transfer of those photons/magnetic waves and twisted in some crazy way, might not smooth out some of perturbations/noise, from the crap an AC waveform had to go through, back to it's generator.  (run-on, much?)        I haven't tested this, actually comparing two circuits, but: it wouldn't surprise me, if a power supply that used a choke, would be less affected by a better power cord, as the former can eliminate a lot of the high freq garbage, etc, that's either created by, or makes it through all the big converting/filtering stuff, before.        Never thought about PCs before the good stuff hit the market, but: the Physics/QED made sense.             I tried 'em, I like 'em and the science makes my head feel better.                               Don't care WHAT it does to anyone else's!

rodman99999 5,456 posts 03-31-2022 at 12:27am         OH, and: it takes some time for the dielectric to form, take a charge, polarize, or however one chooses to define the process, when a dielectric is subjected to electromagnetic waves, which affects the Poynting vectors, measurably/predictably.               The lower the material’s dielectric constant: the longer that takes.                                                PC burn-in?    Maybe?

                                                    Happy listening! 

     My first step (when addressing power to my system) was to replace the 14 AWG, that fed most of my upstairs rooms, with a 20A dedicated line (two twisted together, 10/2 runs of Romex*), on it's own breaker and the bus bar of the Main, with nothing but one side of the 230V, HVAC power on it (I got lucky, there).

                 The HVAC stays turned off, during listening sessions.

                      *My listening room's 120' from the mains box.

       Although I don't doubt that better outlets would improve things, somewhat: I used Hubbell, Extra Heavy Duty, Hospital Grade receptacles.

          That was almost 30 years ago and they still grip like a gorilla, so...

        An Audio Magic Stealth feeds everything but the Main Mono Amps and VPI SDS, in my actively bi-amped system.

         Though the purifier is there to do just that (purify), making it's job as easy as possible has been my goal in PC selection.

                                 From there, I'll hit the rewind.
