For anyone reading this and considering Moode Audio...FWIW, I have extensively used Moode, Volumio, and PiCoreplayer on all my RPi's, ranging from ZeroW to RPi5, and Moode has become my goto setup for all of them, so kudos to Tim Curtis and the Moode team. The reasons for me are
1. Simple installation via the RPI imager program, even for the ZeroW without any ethernet.
2. Seems to more easily support a wide range of I2S dacs, i.e. they just work in my experience, better than the others
3. Supports all my own use cases (mainly local music storage, spotify, basic DSP/EQ options, remote storage also works well for me) - so no real gaps in functionality for me
4. Access from within the app to the SSH web terminal interface (no need to use putty for windows for example) - I use this almost every time I use Moode, to see for example how much adding resampling adds to cpu load (important for ZeroW for example)
5. Uses MPD, which I have found I prefer to LMS/Squeezelite (as used in PiCorePlayer) - just a personal/subjective preference
I have also experienced some very good results with both Volumio and PiCorePlayer, but the combination of the 5 factors above make Moode my preferred option.
I do run Volumio on some of my non-RPi SBC (such as Odroid C4 for example), and it does a good job there, used with USB external dacs only in that case.
