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.

But try asking a EE. I'll be surprised if you get 15%.

Was there something that wasn't clear in my answer?

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.
