Streamer always on?


I just obtained a new streamer (Arcam.) 
Should  the power always be left on, or turned off when not using?

I power down my Node2i at night before bed. You hold the play / pause in the center of the top control for 3 seconds to power it down.

Is that a new feature of the Node2i? Can you do that with the older Node2?
Not sure I never had the node 2. Actually I hold for 5 seconds not 3 and it's called vacation mode , I assume it's powered down as it will not respond to the app until I wake it up by touching the play / pause again on the unit. 
One of the main guys at Auralic, Xuanqian, indicates that he never turns off his device (or put it on standby).  He just sets the screen as auto off and leaves it always on. Their devices do not have a true standby since it doesn't actually reduce power consumption.  So they just call it sleep.  I follow his lead and leave my Auralic Vega always on with screen set to auto off.

I also have Node 2 that I never power down.
