Yes. Speakers. They have bits that move. It's the moving bits that make noise by vibrating. We call this noise music. Vibrating bits vibrate differently at different temperatures. Different kinds of vibrating will make different kinds of noise. It's, like, science. You could call it, "warming up." It's not (just) in your head. Things just start to come together and cohere just so-ly after about an hour with every set of speakers I've ever met.
As for the electronic bits that just sit about and pass electrons, all passive and not moving like, folks'll tell you warming up matters. I leave mine on all the time 'cause it's easier than wondering why I've never heard any difference. But, been years since I've really turned any of it off, so what do I know.....
