This is NOT true. I have measured proof that PURE copper will visually migrate in a day or so, without added energy, except room temperature. I have pictures!
That still has nothing to do with "burn in".
Magura 🙂

Stick it in saltwater and I can get it to migrate in ten seconds.😀

Wouldn't a better word for that process be 'corrosion'?
Why should physical migration be one contributor to 'burn in'?
Beats me, but you brought it up.

SY will always never believe in 'burn in'. It would not matter what I said, demonstrated, or measured.
However, for completeness, read:
'Electron Microscopy of Interfaces in Metals and Alloys', Forwood and Clarebrough, pp 314-325 "6.41
Faulted Defects Generated by the Movement of Boundaries in Electron Microscope Specimens"
Then you will see fragments of pure Cu move over time on their own volition.

Putting the jabs aside, let's assume for a moment that John is correct here. John, can you suggest whether using a higher voltage and amperage would speed up the process ie: 120V 60hz or 220V 50Hz (mains power) or does this break in require you run audio frequencies as this the realm under which this wire is to be used?
Does this effect reverse itself over time if the wire remains idle ie: tempering?
Serious questions, serious answers only please.

It would appear that most cable 'break in' stays, until you radically move the wire, solder to it, or it perhaps corrodes with time. This is based on our experience. This is also because the wire components migrate to their lowest energy state, and would prefer to stay there.

Question to JC
If you believe the properties of cable are changeable, and these "conduction" issues are real, would the idea of an amp (or device) that applies a low level HF "bias" signal across the output terminals of the amp sound like madness or not. Perhaps somewhere in the 60 to 200 khz range, amplitude perhaps 20 to 100 mv rms say.
Or an amp that when "off" applies a small constant current through the speaker and leads, again say <10 ma for example.
Just an idea in thought 🙂

I would not do it, but who knows? Usually, to 'break in' a wire or amp, you want a changing signal source, or at least a source with many harmonics. This is what we have have found to work, over the decades. For the record, it is almost impossible for a manufacturer to fully 'break in' any component, even wires. It just takes too much time, space, energy, and the police get suspicious of what you are doing.
Thanks John,
As I say it was just a "wild thought" idea. Interesting to hear your thoughts though.

Ummm, where's the electrolyte?

Demonstrate and measure. Merely asserting and mentioning irrelevant references, you're right, that doesn't cut it.
Oh well, see what I mean? I have to give up. SY will accept nothing I can offer. I hope others will look a little deeper, or at least, keep an open mind about this. NOW you have come to know what is wrong with peer review. They would have trashed, Darwin, Einstein, and just about everybody else, at least at first.
Nope, I have nothing that would prove that Coca Cola and Pepsi taste different, either.
I saw them do spectroscopy on the old show Newton's apple that prove that Pepsi has at least one ingredient not in coca cola - its on the label - citric acid.
Were cable mfg's this forthright, we wouldn't be having this discussion.😀
I have to give up. SY will accept nothing I can offer.
Why give up? It would be easy for you to provide proof of your claim.
Simply measure the LRC of a straight piece of wire, before and after "burn in".
Such a proof I'm sure Stuart would accept. You could even do it right in front of him.
Magura 🙂
Does Pepsi taste like citric acid?
Yes, and so does the European Coca-Cola. Oh well, let's just call it "taste of lemon".
The European Coca-Cola is pretty much the equivalent of the American Coke-Lemon.
Magura 🙂
What does citric acid taste like? 😉 Pepsi, perhaps? Or if you were to somehow do a differential test, the residual would be largely citric acid.
Lets just for the sake of argument, say that electromigration happens rapidly at room temp. To posit that it has an effect on the sound is like saying that if someone dies after a rooster crows you should blame it on the rooster. How do you test this hypothesis?
