Weightlifting?
I think many would on this thread: Those convinced cables burn in because it will affirm their belief, and scientists either way because it will prove or disprove something for which known properties don’t explain but for which at least most claimed observation doesn’t seem to have been conducted in a way as to eliminate other causes of being perceived to sound different. Should no change is found it closes the matter, while if definitive change is found it takes away the concern about reliability of observation and instead focuses on a need for further research to find the mechanism.
Nice day today. I flew Nice-Paris, had a good business meeting and dinner, enjoyed this thread.
Thank you all for your contributions. I have a lot to think about, I will keep you updated.
You should have travelled on the TGV. Think of your CO2 emissions.
Have a think about grain boundaries.
Copper wire is made up of grains.
Grains have grain boundaries.
Impurities are found at the grain boundaries. (If I remember correctly).
Maybe, the grain boundaries initially restrict flow, but when they are subjected to current over a period of time the boundaries are breeched resulting in a less restricted flow.
This is useful thank you.
I am collecting information on the alloys used to manufacture audio cables. It looks like many of these cables are plated, and irrespective of this we must remember the skin effect.
We would like a simple, elegant theory.
There is a lot of material from Naim on burn-in, be it in cables or components. Perhaps I should visit the factory.
My word you must be strong :0)
According to most sources, including Belden, skin effect isn’t a thing at audio frequencies. Just google Skin effect frequencies
Travelling on a train compared to plane wouldn’t make a significant difference to a person’s CO2 emissions …though certainly less than if they were to run!
TGV is electric. Vastly less CO2 emissions than flying.

That’s why France will be banning some short haul flights.
But the person will not be emitting less CO2 than flying…
Oh I see what you mean. Actual emissions from the person rather than emissions attributable to their activity.
Indeed! The wording of the original post was “your CO2 emissions”
I would suggest that if members wish to discuss the benefits of train vs. flying then perhaps start another thread, although I admit that the diversion here was somewhat refreshing.
We should consider to know if the burn in with a cable cooker is more ecological vs burn in by letting the system 24/24 during 1 week.
If you actually want my opinion - burn in applies to ALL Audio equipment it has just got twisted
off course some how on this thread.
The reason why you so rightly say there are no changes to the things you mention. Is that the burn in change while mildly audible is simply far far to small to have any relevance at all to the
other applications cables are used for and even if could Some how Magnify this effect it is
unlikely to be of a realm which would in any way effect the applications of such cables.
I thankyou for bringing this up as this has not previously been made clear.
Yes the idea of using the writing direction on the assumption the cable is drawn that way if that is your desire - is down to which way around the writing reel is put on and i doubt there
is any knowledge at all of directionality so this can be random.
There is a process that has to be followed so the direction printing should be printed in the direction that the cable and insulation is extruded. Luckily Naim double check by listening, which in most cases confirms all well. Until, something goes (very rarely) wrong, and then thank heaven for the listening checks.
Do you know whether the directionality of the cable is the same of the extrusion flow or the opposite?
It is always the same logic or depends on material, process, etc.?
I don’t know I’m afraid. One for Naim’s R&D.
