Flawless setup and no issues with OS, never experienced any hick ups or reboots. First unfold for MQA songs, I used Tidal mostly on this. Superb sound quality, better than anything I heard. Touch screen or screen with keyboard and mouse is needed and only way of using it. Cannot be controlled from phone, laptop or any other device. Higher sample rates don't have a problem at all. After editing all the root files to get bit perfect it is still not, came to know after I connected USB DACs and played AM files. Sound quality is Ok compared to others OS i used. Can connect USB DAC and HAT DAC, both can be used together. Can install any android app - Main purpose of build was Apple Music. I still have a the above boards, hats and display. I have used and connected following DACs with below OS's: It can be replaced alone without changing the RPI player and would definitely sound better than HAT DACs. I would suggest go for a external USB DAC.

The entire desktop becomes a visualizer and the visualizer plays for any sound that happens in my music room, for speech, any sound that is made in the room including music playing through my raspberry pi players through the amps on my speakers. What I have done is to have my 65" plasma tv connected to my linux PC and installed glava and connected a USB microphone to the PC. It also can play music with RT priority (realtime).

In fact mpd avoids anything that can use your CPU and screw the music. It is not a album manager and no fancy stuff like visualizations, etc are present. But MPD is just tiny program that sends the bits to your dac.

But what do you do when your player doesn't support visualizations or when you want your raspberry PI to give the best possibe music and hence turn off GUI and run it in run level 3? Also when you want to play bit perfect music, nothing beats MPD - Music Player Daemon interfacing with your DAC and giving the best low latency conversion. Various music players have visualizations (kodi, clementine, etc). I have tried various visualizers on linux.
