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

Back in the eighties, I bought a pair of expensive IC’s. Until that, all I ever used were the thin cheap cables that came with cd players. OMG was the difference huge! From that point on, I believe that cables mattered.  In the last four years, I’ve bought seven power cables (all $500 and under.) and to be honest, I’ve not heard a lick of difference, but I definitely am not going to yell and call people names because they can hear something that I cannot. Maybe someday I’ll be able to try some expensive cables and see if then I can hear an improvement. But until that time comes, why should I care what others think? Or how others spend their money?  When it comes to HIFI, I trust my ears and not others beliefs.

I believe that I can hear the difference between cables that I have put into my system.  The physics of why that is the case . . . I haven't the slightest idea, although it seems like manufacturers believe that they need to say something to explain why you need to fork over sometimes big $$ beyond "buy my cable . . . it sounds better" and we end up with a bunch of technogobbledygook that probably has nothing to do with why the cable sounds different but sounds very scientific -- MIT, I am thinking of your "poles of articulation" nonsense.  So, the debate regarding why cables sound different continues and until some group designs a method of doing a real A/B blind test that eliminates any variances other than the cable, this debate will go on and on.

This brings me to the next logical point.  If it sounds different, shouldn't that show up in some sort of measurement on REW, or an oscilloscope, or at least something? If not, why not? 

@dill. I take objection to your post. That attitude would seem to place you in the 1% crowd who seemingly has sufficient resources to continue to upgrade equipment seeking to lift that final veil and achieve nirvana. For the rest of us 99 percenters. we are resigned to reach a point of good enough.

Being a KEF fan and owning a pair of R3 Metas, the implication is that I shouldn't be happy until I have a pair of Muons sitting in my living room. Just maybe I'm unwilling to sell or mortgage my house or clean out my retirement accounts in order to meet you lofty standards. Yes, I am a proud member of the good enough club.


llg98ljk - Your comments about me are not accurate and if you read the other posts by classicrockfan you would understand where I am coming from.

"the implication is that I shouldn’t be happy until I have a pair of Muons sitting in my living room."

- I made no implication to you of any kind.
