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

I don’t drink, so it must be the electronics. But actually, I do think after about 20-30 minutes things do sound better, more focused. I know that the cartridge always sounds better after the first side, I usually play a side of a LP that I don’t plan to listen to just for that reason. It lends to some credibility to the Audioquest DBS cables keeping them "charged" and for none DBS cables they must have a re-establish or break in that takes place when not in use or a while. Just my theory and not trying to start an argument on the subject, but I do normally put on some music while I gather the LP’s I plan to listen to before I sit down with my non-beer to relax. Again my theory and my way of doing things, ymmv.

My Krell monoblocks 450mcx clearly sound better after about an hour playing.
I also try to run a cd for awhile prior to listening session.  And only after leaving all 
electonics on Stand-by almost all the time continuously KCT and  KPS 28  cd.
If I shut off everything cold it sound poor for hours until warmed up
I'm amazed how warm my KCT remains even in stand -by mode and amazed how poor it sounds comparably  if not warmed up
Best sound is after a hour of playing with or without beer
I too enjoy a cold beer while listening.  I have kept these things in stand by mode for years now and only usually listening on weekends
I play cd and vinyl equally

The last time my system sounded bad, it had been off for 24 hours. I had forgotten about it when I sat down to listen, it had been on already a couple of hours, but ugh. I kept asking myself "why does it sound so bad?" until I remembered.

So, it's not entirely the beer.

This and my really random/erratic listening habits keep me away from tubes.

Had an interesting event courtesy of Music Lovers in San Francisco. I got to listen to the ARC integrated.

First, sounds good. Then over the next 30 minutes or so sounds really hard and grainy, and then it swings back to velvety smooth.

NO idea why.

I don't drink either. Well, I sometimes do but under different circumstances.
Two hours of warming up, after that I don't hear a difference. And I mean not playing anything for two hours. If playing, I can't be certain but I think it improves up to one hour. Mid-level solid state electronics, dynamic speakers, MM cartridge.
