Running in????
That's funny on many different levels...
I bought a pair of Mission M35s and a Marantz PM7200 about 10 years (ish) ago. In the shop, the setup sounded warm as a blanket (I liked big bass and a warm sound at the time, so this setup was perfect). When everything arrived, it sounded pretty harsh tbh. Then over the course of a month (without moving anything I might add) everything warmed up quite nicely, and sounded like it did in the shop.
Elastomers and rubbers have very complex deformation behaviours. Their physical links are not permanent, and the chains of monomers are subject to deformation. This may manifest in a reduction in stiffness in use over time, effecting the inertia of the speaker cone. Its only logical to assume a bedding in period as the material moves from its static and unused state to its deformed state after use. Its been a loooong time since Ive worked with materials though, so I may well be very rusty

Paul, I am not saying there is nothing happenign with materials (in the first hunderd or whatever hours of use). What I am saying is that nobody could describe in specific terms or demonstrate otherwise that these changes affect sound to any material degree. If change in the material in such short period of time/use was so significant the product is flawed. I am saying is that these changes are not audible and maybe even not measurable. I am also saying that if you tested yourself blind you would not be able to tell a difference between an out of the box speaker and one that has been 'run-in'.

An easy boast to make, as it would be impossible for me to test a brand new pair of M35s agains a bedded in pair. I am not disagreeing with your experience however, bearing in mind your system is much higher spec than everything I have owned. I respectfully disagree however, as it was not a small diference between the shop speakers and the new pair. Sad face on christmas day, Paul was disappointed 
Can you explain how you know this? Please show your workings...
I have had my dali lektor 2's since tuesday, i have noticed a steady improvement in sound quaility, they sound warmer and more smooth, is it the speaker breaking in? or perhaps my ears getting used to them? whatever it is, clearly something happens.

Wrong way round.

Wrong way round.
So only one side of an argument has to provide any evidence? Interesting...

Not what I said.
So, I ask someone for proof that speaker burn-in isn't necessary, you tell me I'm wrong to do so and then provide exactly the evidence I was asking for? That's slightly odd...
