Got a 120, couple of questions

[ogs]

Hi all, I am thrilled to be a new 120 owner. This unit represents everything I want in a piece of hifi. I am running a Rega P3-24 and a MacBook Pro/Air 3.1 Beta for Spotify and iTunes streaming, as well as a Chromecast Audio also for Spotify which may soon be sunset if Air 3.1 continues to prove stable. Speakers are KEF LS50, and I love SAM. This system is used on the desktop and will get a ton of hours.  

I have been playing with settings for the last few days and there are a couple of general settings that I have questions on.

1. Is anyone not using dynamic power management? It appears to be default as of the 8.x firmware. Not sure I love the concept for a piece of hifi but Devialet thinks it is worthy of a "default" designation. Would love opinions on this, I have yet to A/B. 

2. What about putting the unit to sleep? I have the display going dark after a few seconds during normal operation, and then the unit goes into low power after after 30 minutes with the display still completely black. Then After another 60 minutes, the unit goes to sleep and actually powers on the display (very low brightness showing "Devialet 120") while also requiring all of the settings to be reloaded before the device will play music. 

I am leaning towards disabling sleep, and just letting it stay in low power mode in order to keep the display always off and avoiding the 10 second bootup while coming out of sleep. Any reason not to do this? 

Thanks

I turn off DPM when I listen to music, but keep it on when the amp is not in use. There is around 10 degrees lower temperature with DPM on. I *think* I have better sound with DPM disabled, a little rounder and more coherent, better sound stage detail, but the difference is small. This is with 9.0.1. 10.0.2 may have changed this (my amp is a 250).
I keep sleep mode disabled  and use the low power setting as you do. I also like to have the display go dark. The amp uses around 15 minutes to sound it's best after start from sleep (cold) mode so that is one reason for not using sleep.
One more reason for me is that I use a microRendu. There is a bug in the combination of Devialet and microRendu in squeezelite mode where microRendu 'looses' the DAC on input change or the amp comes back from sleep. The fix is as simple as restarting squeezelite on the microRendu, but I prefer to keep the amp on.
