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

@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!

 

Two Styrofoam cups and 20 feet of string works great for me.

I order drinks from my wife, Wilma, in the kitchen for my friend Barney and me.

 

Fred,

Yabadabbadoo!

Thanks for all your inputs. Filtration through the common mode choke EMI combined with galvanic isolation of the transformer should be able to eliminate unwanted signal noise completely. This is not my opinion but one of the established principles of signal electronics. But I agree with you on "   however good the filter, the cleaner whatever goes in: the less work the filter has to do and the cleaner the output." Happy listening!

You got the usual response from the folks who have crap for audio systems, can’t be bothered to try, or have genetically inferior hearing.

That said I think you have left out a lot for other factors on cable break in.

One of many others that can’t ignore is that electrons are physical particles and are charge aligned as they leave an amp. .
flowing thru a cable with metallurgical imperfections will cause the electrons to bounce around and get displaced in relation to each other. Overtime some level of these Imperfections will get smoothened out just like water will do to rocks overtime.

This I also believe is another factor for break in. I am sure there are more reasons causing us with better audio systems and ears to experience cable break in differences.

 

@tomic601 -

                                  As I've mentioned in the past:

     Feynman was and will remain, my favorite lecturer (yeah: I'm that old).

     He mentioned often (and: I took to heart) his favorite Rule of Life: "Never stop learning!"

     For all his genius, he never grew overly confident in his beliefs.    The perfect obverse to the Dunning-Kruger sufferer.

     ie:  “I can live with doubt and uncertainty and not knowing. I think it is much more interesting to live not knowing than to have answers that might be wrong.”

     and: “I have approximate answers, and possible beliefs, and different degrees of certainty about different things, but I’m not absolutely sure of anything.”

     Tesla is probably my favorite innovator, who (despite the incessant, projectile vomit, from his day's naysayers), took the World, kicking and screaming, into the 20th century, with his inventions.

                                                  His thoughts: 

     “Anti-social behavior is a trait of intelligence in a world full of conformists.”

     “All that was great in the past was ridiculed, condemned, combatted, suppressed, only to emerge all the more powerfully, all the more triumphantly from the struggle.”

                                                Happy listening!
