Is it the beer or do speakers/electronics really need some extended warm-up period?


To me, one of life's best times are a cold beer and listening to good music.  I have noticed that the longer the listening/drinking session, the better the sound.  Is it the beer or do the electronics/mechanical components mellow out after some burn-in period?  Thought about listening with no beer, but that's not happening.

Electronics and speakers (cone type) do in the sense of getting maximum SQ.  They do not _need_ it to work and sound "ok."

It may help to distinguish daily warm up from initial 'burn in'....
Interesting about some systems sounding worse with warm-up.

Yea, I didn't mean burn-in, just playin time.  I imagine components properties change after being stressed and the best designs account for this?
I think most audio manufacturers believe their equipment benefits from an hour or two of being powered on. At least McCormack and Ayre and Atma-Sphere recommend keeping things powered on for a while.

I usually let my amp warm up for an hour or two before listening. I throw on just something for the first 15 or 20 minutes before sitting down to really listen and that seems to make a difference. I don't know if the speakers or amp, but there's a difference. 
I usually let my beer warm up for about an hour before gulping it down. 🍺 😛
