The molecular level explanation of "cable burn-in"


According to one cable seller

"The insulation (or dielectric) will absorb energy from the conductor when a current is flowing (i.e. when music is playing). This energy-absorption causes the dielectric's molecules to re-arrange themselves from a random order into a uniform order. When the molecules have been rearranged, the dielectric will absorb less energy & consequently cause less distortion."

So it’s the plastic polymer (as dielectric insulation) to undergo some sort of molecular rearrangements to minimize the distortion. Probably one of the greatest scientific discoveries ever!

“Many premium AC cords constrict or compress the audio transient as their characteristic impedance restricts the transient current.”

We all know impedance restricts current but how possibly “many” premium AC cords constrict/compress the audio transient (when not carrying audio signal)? Then again is it achieved by this molecular rearrangements of the cable insulation?

Unfortunately there are no measurement data or mathematical formulas to be found to back up this amazing scientific discovery. Simply “it happens”. So I came up with a formula for them.

∆E = P - SoT

∆E: energy absorbed by dielectric

P: energy (power) drawn from wall outlet

So : Smake Oile

T: Dielectric Transition Temperature

I could be mistaking, however I don't see a long visit by the classicrockfan on AudiogoN.

the cleaner the power (from the wall, cord, fuse and PS), the more faithfully the resultant signal, when it reaches your speakers for reproduction.

Do you know what EMI filter does and where it's located and how those x/y capacitors and common mode chokes work together to swamp out all EM interference noise that the power line picks up right from the power grid (not just the last 5 feet from the wall outlet) to your audio equipment. Yes the EMI filter should swamp out all RF signal from the power cable so the noise can't make it through the power supply of the audio unit. You just need a cable big enough to carry the current without heating up. And that's why you don't need a power conditioner either to clean the AC power from the wall outlet.

I bought amazon power cables for less than 50 and I love them because they please my eyes. They don't make my audio system sound any better than the stock power cord. What about $1000 power cables? A total waste of money. Nonetheless we all know "placebo effect" is alive and well so you'd believe a $1000 cable/the magic oil lamp makes your system sound better because you feel better about it.

Go find something better to do.

@rodman99999 All good…. i’m mostly in your camp… The moniker is my favorite salmon fishing plug… A serious boat and multi-quarry season make high end audio SEEM affordable ….

 

Ido hang out a few hours a day working in the Quantum computing aka bleeding edge industry… A great read for the Luddites is of course Surely You’re Joking Mr. Feynman.

While, i also fondly miss Almarg, i think he would like myself be the first to say we don’t as yet know everything and that lots of very interesting science is happening outside of Physics and EE. My memory is he worked on radar gear…. my own experience w phased arrays both orbital and not is that the absolute frontier of high performance is… still partly a black art. …..

I parse my consumption of threads like this…mostly to define who to skip over and who to focus on….. love to learn…

Of course, i believe forming a dielectric  and maintaining that state is important…. the amplifiers i use have a 128v DBS circuit for just that purpose…..

You ( those high on PS audio advice on speakers…should poke Paul about Octave and the microphone collection / selection…. my position would be work transducers hard… and for those in the digital world, PRAY they used a fantastic A2D….

@classicrockfan -

Is F=ma one of his theories? I know his theory of gravitation but not sure about his other theories.

    The main of the EFEs I'm thinking of is: G+A= kT, but- if the, "a" in your formula is lamda: YES!      We're on the same page.

 

     You do realize: that you own Kimber products, already puts you in the, "better cable" klan, right?

      Kimber (to my knowledge) has never made an inferior product, or- one that didn't punch above it's price range, as some would say.

       If you read my prior post, regarding how I'd suggest a power cable might be designed, you'll note my mention of Teflon dielectric and Litz.    Your 8TC speaker cables are a big Teflon dielectric, Litz (braided) cable.

       The design has been, "good enough" for a LOT of people, for a LOT of years and why they're still being made.

       They're good enough for my driven subwoofers and I could probably live with them on my mains (though I'd rather have 12TC), if I ever had to give up my Big Silver Ovals).

        Even Kimber's PBJ will outperform a lot of higher priced cables, IF your appetite leans towards a more faithful signal transfer.

         I had Heroes on a couple sources, a few decades back.   Tried a number of other of the better regarded brands and have been using pairs of KS1030 and KS1130, for the past 20ish.    I just feel they've remained consistent with the rest of my components and their upgrades.

"Do you know what EMI filter does" and so on.

         Yes.   I've a few decades of electronic repair, restoration, upgrading and building, behind my comments.

          One thing even the most inane EE should recognize: however good the filter, the cleaner whatever goes in: the less work the filter has to do and the cleaner the output.

           Typically: the first upgrades and/or replacements  I address in whatever the component, are in the power supply, because: that's to what you're going to be listening.

           I also mentioned that a power supply with a choke may respond less, to a high dollar PC, as they clean up a lot of what makes it through the rectifiers, x-former, caps, etc.

                                              Happy listening!
