Should a CDP be left on 24/7 or shut off & on?


I read once on Audio Critique that digital eqipment should be left constantly on. Over the weekend I had to disconnect my Rega Planet Original for for 24+ hours and, frankly, do not hear any difference from when it was constantly on. This obviously is difficult to A/B.
What do you do with your digital equipment: leave it on 24/7 or power it down when not in use?

Thanks.

I think you have already answered your quesiton. If you heard no difference in sound with it off, then there is no reason to leave it on. Trust your ears.
Some of you guys leave tubes on 24/7? What is the logic in that? Tubes only take about 30-45 minutes to warm up.
Robm321,

If you have not noticed already - there isn't much logic on this forum. ;)

As for the subject, I only leave my Integrated on - CDP stays off.
