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.

Seeing that the answer may depend on the model of my CDP, last night I sent the question to Rega themselves & received a response:

Question: Is there any benefit to leaving my Rega Planet powered on all time or can I shut it off when I am not using it?

Answer: The Planet will not come to any harm if left on permanently, however in these environmentally aware times I would always recommend turning the player on 10 minutes before use. This will allow it to warm up to optimum temperature, save electricity and prolong the life of the CD player.

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.
