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.

mesch, it might be reasonable, but in the comparisons of gear I conducted it was not audible. i.e. it's not significant
A glass (or3) of good Champagne with a good smoke (of your choice) alway makes my system come alive. 
Must be the long warmup🤔
ANYBODY whose owned a class A SS amp will tell you those things need to warm up. The bias in my F5 doesn't settle to what it should be until it's been on at least an hour and I only do final tweaks after 2 hours when it's completely warm. Until it's all hot, things are drifting all over the place. Somebody wants to tell me that makes no difference?
Maybe I'm delusional or have crappy, thermally unstable amps, too, but my CAD211fes and 500MBs sound better after about 30-45 minutes of warmup.  Not that they are "bad" cold, just seem to smooth out a little bit.  Seems that way whether I stay in the room or turn on, leave, and come back after a short while.
