jadis js-1 dac... leave powered up or off?

I don't have a manual, This has separate powersupply
the power supply has a digital toggle switch that-
lights up Red & an analog toggle that lights up Green.
My Question is, should I leave it on digital mode
red light when I'm not playing it or shut it off completely? I play it everyday. Also on the dac the
first 2 green lights go on, the third doesn't go on.
The unit plays & sound's Great. Using with Wadia #20 transport, Jadis DP-60 preamp, Air tight amps,martinlogan CLS speakers. I listen to opera,classical&jazz, Thanks...
