I have 2 servers running, one is a NUC which is always on. I have it running a number of docker images that I want to be on all the time (CF tunnel, Crowdsec, NGINX PM, Vaultwarden, Plex for music, Audiobookshelf etc) this also serves as a gateway/proxy. I also have a bigger machine which I can run when I want. This serves my plex video collection and other services I don't need 100% uptime on.

I recently purchased a nice amp with built in DAC and speaker setup. What I would like to achieve is a headless plexamp docker instance running on the NUC so that I can connect directly the NUC to the DAC on the amp and play my music directly in high bitrate. I also have a small 10 inch monitor that ideally if possible I'd like to display the track details and album art of the currently playing track.

What is the best way to achieve this? Should I run plexamp headless on the NUC, or get a separate pi to do this? Also, as I cant find a linux driver for my amp does anyone know whether there are generic linux audio drivers to support DSD/high bitrate music playback through a DAC. I guess my other option would be to run a windows machine to do this, but if at all possible I'd like to avoid this. Has anyone had any success in a similar setup? Also does anyone know if the album art thing is possible?

If there is a better way of doing this then I'm definitely open to ideas. Basically I'd like to be able to sit down on the sofa, queue up sone tunes on my phone and have them play at max quality, with a nice little album art display.
