My tube preamp is only turned on when I'm actively listening, though I wish I could plan ahead and let it warm up for 20 minutes for better performance. The tubes have a finite lifespan.

In the past I have kept digital components on all the time (like a CD player or AV receiver). I know some audio tweaker expert suggested it, but I can't remember who. As long as the components aren't overheated I don't think it would hurt them.

Now, with two kids, I listen so infrequently that I keep everything off or in standby if possible. If I listened everyday after work I would keep the digital components on still.
