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

I get burn in... should be called burn off just to get the manufacturing process off all the different manufacturers and parts to sweat off the packaging and sealants. But a light bulb is on or off. So SS gear in theory should sound the same. A light bulb does not get brighter after an hour. Is it your ears get programmed? Or is there and actual technical reason that it sounds better? Please pretend Im a four year old cause with Electronics I am.

@Millercarbon,
If you haven't anything nice to say, then keep it to yourself.

Thank you Al for mentioning that semiconductors are sensitive to temperature. We often forget it, concentrating on less important factors. Thank you also for providing Wikipedia link, for those who want to learn more, since semiconductor behavior with temperature is complex.

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.
That's about as layman an explanation one can give, and it was his first paragraph.

All the best,
Nonoise

I hate to judge before all the facts are in but tube electronics are also apparently subject to variation in temperature, at least in terms of warming up. That’s the way thing are.

I look at it as a performance cars, they perform better after they’re warmed up.
