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.

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

@almarg ,
Made perfect sense to me. 👍

All gear warms up. Any device attached to said gear must operate within design parameters as the gear warms up. It stands to reason that somewhere within the safe operating temp range there is an optimum or "goldilocks" value where the device operates best. 

Best guess is to say that it's not at it's coldest or not at it's hottest, leaving that area in between where it's performing at it's best.

Just to boggle your mind a bit, here's some experts takes on temp limits of capacitors from some pretty smart people: https://www.researchgate.net/post/Whats_the_meaning_of_the_limitation_of_the_temperature_of_the_capacitors
Granted, it's off topic a bit but it's relevant in that devices will warm up regardless of how you feel about it's performance so it stand to reason that the devices do have an optimum operating temp, and it's not at it's lowest range, at least with respects to audio gear.

All the best,
