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

Resistance and capacitance are some of the electrical properties that change with temperature. For the electronic equipment to be able to properly measure and provide accurate and consistent results, these instruments must warm up and stabilize thermally. Some argue that ‘warm up’ may not be the right term to use, as some devices sometimes need some time to stabilize thermally.

If you look at Sterophile's test measurements, they always warm up or per-condition the equipment prior to testing.

Let’s have an oil thread!

Not.

Thank you "Test pilot" now I hearing a language I understand. SS gear should be rated at an optimal "Operating Temperature"  then... Be interesting if the ambient temperature (the gear was pre heated or your house was lets say 110 degrees if that was perfect for the SS gear prior to electricity was applied) would change SS sound in any way.

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.
