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

There are warmup dedicated CD's I use the bellow :

At the big shows like CES almost all the rooms sound terrible on Day One. That’s because everything, the speakers, the cabling, the electronics are new. Now why anyone would think that was a good idea is a subject for another discussion, but most systems, including the really big expensive systems, didn’t sound even HALFWAY good until the THIRD day, which unfortunately is usually closing day. Pretty funny, in a way, right? And in many cases that was ONLY because the systems were driven all day and all of the night for two days straight! Hey, sounds like a Kinks song! 

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.

@erik_squires , When I ran a solid state preamp many years ago (Fulton modified Bravura), it really didn't sound right until it had been on for about 24 hours. This was so consistent I wondered why it was equipped with a power switch since it drew so little power.

We consistently hear changes in our gear as it warms up and its easy to demonstrate. But only an hour is needed- and really its only the first 15-20 minutes in which the gear shouldn't be taken seriously.

In terms of warmup, it sounds like tubes can do that faster than solid state; so I'm curious how that keeps you away from tubes?
