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🤔
