Many years ago I worked at a professional recording studio where they left their (all solid state) equipment on 24/7. When I asked the most senior engineer about that, he said it was because there were way too many things to power "on" in the morning and to him, the extra electricity didn't cost him enough to sweat it.
I do not leave my equipment "on" all the time, all digital/solid state. Yes, I do hear it sound a little better as it's on for a while, but after 20-30 minutes, it seems to sound as good as it will get. My equipment doesn't get hot at all, it's all barely warm to the touch (except for my DAC).
