soften up over time. That warmish, relaxed in the treble thing. Which component(s) cause that?
TIA

Your perception of the sound changes. The ear + brain combination is not an instrument that can provide an objective analysis of sound reproduction.
Depends on the length of time.
I don't deny it's partly due to capacitors, but your brain also adjusts. This is the tricky part, because it seems to be based, at least partly, on experience: recent, as well as past, and varies from person to person. But I am sure there is also some "nature" involved.
Right you are. Caps have a short period of break in while the brain takes somewhat longer.
Too much is never enough
Same reason your wife wants to paint the living room a different color every... two years? :)
Capacitors come from the factory "unformed," I have been told, and it takes a certain amount of cycling for their dialectric to adapt to the place in the circuit where they are.
I of course have no independent proof of this, it could be just an EE Urban Legend.

My Maggies were fresh out of the shipping box.
For the first (maybe) 15 to 20 hours, the image would 'jump' between speakers or even have a momentary dropout.
The ONLY thing I could blame it on was Capacitor Formation. I went thru a similar situation with my Studio Stobe lights which have a huge amount of capacitance to provide long flash times.
All that being said, I have NO idea if a capacitor 'knows' where it is being used.
Too much is never enough
Every wire has a dielectric that has to be formed, supposedly.
Does the molecular structure of resistors change? Do THEY require break-in as well? I don't recall anyone pin-pointing that as a potential issue, so maybe, not.
Do capacitors that need to 'form' or other parts requiring break-in ever sound worse? I've never seen a review or manufacturer that claimed a product sounds bad after 1000 hours so don't play it beyond that. ;-)
...tubes ageing.
If it's solid state, then I'd guess oxidized connections throughout if they haven't been cleaned with DeOxit in a over a year.
