Can anyone explain in laymans terms why your gear sound better after warm up

Temperature is a parameter that is fundamental to the physics of transistors, analog and digital integrated circuits, and other semiconductor devices. Consequently their behavior varies significantly as a function of temperature, and a competent designer will design the product to perform at its best when it has warmed up to a stable internal temperature, while being used in a room that is at a normal room temperature.

For an example of how transistor behavior is a function of temperature see the paragraph entitled "Ebers-Moll model" in this Wikipedia writeup on bipolar transistors, and note the capital "T" (for temperature) in the various equations.

That's just one example. There are many other effects temperature can have on various kinds of semiconductor devices.

" cleeds2" is right. Everything is better with beer.

I've never made that claim.

I really wish I could. I can tell you I have had remarkably different experiences with different gear.

My current integrated takes no time at all after the muting relay has disengaged. It’s a class A/B amplifier. My Class D amps can take two days. However, I can only tell this for music, if the amps have been left off for a day. For use as the center/surround amps, they play perfectly well even when only switched on irregularly.

I have no idea why.

I stand corrected and applogies Mr. Cleed.. " Is it the beer or do speakers/electronics really need some extended warm-up period?" 

You were making reference to my post / question...

Pretty sure its gonna take an PhD EE X 3 / Designer or Nelson Pass to give us a real answer here about Solid State gear and warm up . And I personally think music sounds better with beer. Haha! Please lets not debate Amber or Stout.
