Class A solid-state power amp gets turned off when not in use because it runs hot and pulls a ton of electricity. It takes a little while to warm up too, but it’s not worth the current draw to leave it on all day.

If you’ve been to any hi-fi audio shows, you are in the one of highest 2 categories.
