My guess is its mostly about electrolytic capacitors. They're the staple on power supplies and they have equivalent series resistance (ESR) which is fairly temperature sensitive. Higher temperatures lower the ESR, improving the effectiveness of the cap in reducing power supply noise.
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.
