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

I turn my system off (always have) when not using it. I believe it stabalizes in 10 or 15 minutes. I don't hear any difference and figure I'm saving precious resources.
Also, I've come to the conclusion that I don't listen with the same intent or intensity as some others on this site.

If it doesn't have tubes in the output, leave it on all the time.

No harm in leaving it on. Having said that...if the player has a standby mode you can probably use that. Most better players with standby are designed to leave that part of the player on that has the long warmup parts; and they shut off things like the display and the transport which don't matter to save power.

My CDP specifically says this in the manual.

Check the manual or the manufacturer if you like. Cheap players also have standby, but they really only leave enough on so the remote can turn it back on.

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.
