New SACD player Marantz SA8001 : leave it on?

I have decided to keep the Marantz SA8001 SACD player. Can I leave it on all the time? Is it better that way, as far as longevity of the unit and sound quality are concerned?

*I think* the sound quality should be better as it will not have to warm up every time I turn it on.

I used to own a Wadia 301 CD player and the manual suggested to leave the unit on for longevity and sound quality, and the laser will be off by itself when not playing.

I also owned the Benchmark DAC1 which did not even have a on/off switch!

I consulted the Marantz manual but I did not find any related info on this matter. What do you think/know?

The Marantz is connected to a PS Audio P300 so power stability should not be a real concern, I only need to know if leaving the Marantz on will be 1. good for longevity 2. bad for longevity 3. doesn't matter

Thanks!
