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.

It’s definitely not the beer.

Just turning my rig on and letting it warm-up for an hour or so has never paid any discernible sonic dividends. Of course it’s better than no warm-up time at all but I discovered years ago that at least 20 minutes of actual system playing time is the magic number for me. Don’t know why....

Just to be clear, I think the 'warm up' (at least that i'm referring to) involves playing it- not simply letting it stand idle after turn on. @hifijones -thanks for bringing out that distinction. 
But kidding aside at least an hour warm up will start to bring out the beginnings of what will sound better and leaving it on over night (which I prefer) sounds the best in my opinion. At one point and a few years back I had some components that the longer they were left on the worse they sounded, no doubt a poor match for the speakers.
