Do amps sound better when left on for 30 minutes ?


Do amps sound better just by having it left on for a while, or do they have to make sound in the warming up process ?

My experience is that they don't warm fully unless they are playing music. I can leave my kW500 on for hours and it still needs playing time before it performs at its best.
I have a tubed amp and preamp and they always sound better after a warmup time of 30-60 minutes.
I have tube equipment and turn them on and put cd on ( low volume ) play for 45-60 minutes..Usually cd is finished and is ready to go.......
I warm up tubes in amps 30-45 min as to not stress the tubes and shorten their life span. It seem after an hour to an hour and a half of playing everything starts to settle in and the system sounds more liquid (homogenous).
