You will find the same sorts of conversations about wines, whiskies, tobacco, cheese, art, probably TVs as well. Are there differences/ improvements? Yes. Can most people appreciate them? No. Does it matter? No. Do you appreciate a £30 wine more than a £10 wine enough to justify the expense? The same applies to high end music systems.

Like any component with moving parts things need to settle in.  I can imagine the diaphragm and the glue which secures it will stretch and soften a tiny amount at first.  Demo speakers and headphones in a shop have probably been through such "running-in"
 
Whether anyone really can tell the difference I don't know - I think a lot of it is audiophiles trying to justify themselves and their supposed expertise/opinion.   

A freshly made speaker will have a tight suspension, but before it leaves the factory, it will be tested and the suspension will have settled in 2 or 3 seconds.
In my youth I could hear getting on for 20khz. Nowadays, I'm lucky if the tinnitus allows me to hear 10khz. I used to have expensive Quad hifi, but now I use a Sony compact system.

I'm going with the myth theory.

I have never heard of this before! In you shoes I would take a cynical view of this claim unless I could find some, what I considered to be unbiased, evidence. My son-in-law is a sound engineer, so I will ask him his opinion as I'm now curious.

No Aurora Australis (although it was visible at Kiama, apparently. Kiama is not far south of here), but there was a nice moony at the bus stop last night.



Incidental to this, I called into the newsagent, and they had MRJ #300 in there, Some great pics of Chris Pendleton's layout in there. In the snow.

I have a feeling you didn't find that.

What a coincidence - I found one in my back garden too.

When they say over £1,000 the current price for one of these is over £1,800, makes N look cheap.

When I was looking for a mini Hi-Fi last year (for Christmas) some YouTube reviews of different makes and models referred to the speakers "settling in" or "burning in" before their true sound quality could be determined. Now I'm looking for a set of (over-ear) headphones and again several reviews talk about devices "settling down" with time to appreciate the sound quality.

Is this an actual thing that happens with all devices, is it something that us ordinary listeners will not notice; or is it a myth that encourages debate amongst experts ?

If it actually happens I wonder about the value of listening to anything in the shop before choosing which model to buy !

Please help educate me !
