Stupid question of the day: Should I leave Amp on?

Joel:

In my experience it is more important to leave the DAC on than the transport. The DAC takes days to get going - mine takes ten days to sound right! I'm serious. My transport is usually good after a couple of hours. With a one box player I would be very tempted to leave it on the whole time for the DAC's sake.

Not a stupid question at all - we're all here to learn. My gear stays on unless I am away from home for an extended period, or there is a thunderstorm - in either case it gets turned off and unplugged. I agree with Sean; most of the equipment I have owned during the last 15 years needs a couple of days to get spun up.
