So you can "break in" a set of headphones? I thought that the sound that comes out of them always remains the same.
Oh, child, you have such a rewarding journey set before you.
Yes, Brand New things that move require time to move a while before they relax into the best version of what they are or can be. Cars, toasters, plumbing fixtures, etc.
Headphones work by moving. Hard to see sometimes, but as they "relax" into to the way they will perform for most of their life, they change the way they sound.
Not always good, but good OR better is the hope as you "suffer" through the break in period.
Sound equipment often gets BETTER as they get used to being used. That, in essence, is the hope, while one endures break in.
Yet there are lots of people who claim there is no such thing as break-in on headphones. They are wrong, it's that simple. I'm an audio equipment manufacturer's worst nightmare and will invariably hear if there is something wrong with the product. Ask the Sennheiser tech who eventually gave up and granted me a fresh pair.
It's sort of a curse sometimes, too, because few others will hear the difference and understand what I'm on about. Explaining what I perceive as insurmountable problems with a product is an absolute pain.
So break-in is absolutely real and actually a wonderful thing because the discovery can be amazing. Such is the case with the Dali speakers. They're not yet for critical listening but after a first, very satisfying, tuning of the Denon amp yesterday, they are getting there. Falling in love with them.
