The vast majority of the people who 'buy in' to the notion of hi-fi component burn-in are NOT kids in school (or who have recently left school).
Component burn-in has been talked about/promoted/recommended/believed by certain manufacturers, magazine reviewers, dealers and enthusiasts for the whole of the 30 years I have been interested in hi-fi.
So you should be addressing the accusations about standards of scientific education in schools to another era. To the era when the (mostly) middle-aged folk who believe this stuff were at school.
I don't think that peoples age or when they left school has anything to do with it.
andyjm thinks it does. And he is an engineer.
As for burning in cables, this only illustrates the paucity of technical eduacation in schools these days.
He blames the standards of technical education 'these days' for things like a belief in cable burn-in.
Not technical education a generation ago, or some earlier time, but 'these days'. I take 'these days' to mean during the present and recently.
That is why I objected.
People receiving their technical education 'these days' are too young to give a #### about such hi-fi tweaking fads that are at least 30 years old (or even older) and are - in the most part - something familiar to a few, much older, hi-fi enthusiasts.
Frankly the entire subject is obsolete. Only a very few people know about such concepts and even fewer care. Just like cable directionality* it's very old news and is not even controversial any more. (You need enough people who give a #### to make a controversy.)
*andyjm will probably trot out another lecture on directionality now I've mentioned it. Please don't. That subject is even older and even less interesting if that's possible.

But anyone who thinks that the conductive properties of a copper cable will change over time* clearly has a limited understanding of basic GCSE level physics.
I suspect the GCSE Physics syllabus doesn't really mention it...

If it had, perhaps I would have continued with physics after the age of 13.

Yeah, black holes, dark matter, supernovae, power from nuclear fusion... etc. What a yawn to a 13 year-old physics student when compared to the excitement of corroding copper and it's adverse effects on an audio signal!
Actiually GCSE level science does teach the conductive properties of metals in school.
Don't you remember being told about capacitance resistance and inductance in physics?

As individual concepts yes, but not in relation to how it differs in different metals, no (A-level physics student).
No signature worth mentioning...
Yeah to be fair at the time I was far more interested in chatting up the girls in my class and learning about a different kind of physics to bother listening to what the teacher was saying about capacitance resistance and inductance.
I'm slightly disappointed that your original post was moderated, meaning I couldn't make any reference to directionality.
However, my point was that whilst resistance etc is of course discussed at GCSE, its potential to change behaviour given different circumstances (stress, temperature, whatever) is more university level...
Anyway, burn-in of cables is b-llocks. Can we move on?
In this thread? Are mods not highlighted anymore?

Sorry about that post JD. Bet it made you giggle though.
To be fair I think you're probably right there. My bad.

Pleeeese people let's move on. Cable burn in doesn't exist.
Only if it's an in-line mod/edit as opposed to the whole post being unpublished for being too unpleasant to contemplate. I still get to see the unpublished ones though.
Naim cable is directional, so whats that say?
It says that their marketing people are working hard.
It says that Naim are talking b-llocks.
