How about a Bluesound Node2i for $499?
Pros-
It will do everything you want to do, play your library, use your phone as controller etc.
It is designed to be a music server.
It will play MQA and stream music via Tidal, Spotify, etc, etc thus giving you a much bigger library of new music and titles you don’t have.
It fits within your budget and has a good, up to date DAC.
The software can be updated, should last longer than a MM before it will be non-useable.
It should sound better than the MM.
You can upgrade the DAC later, thus improving the sound with time.
Cons-
It will not function as a computer, cannot do all those things.
You will not be able to load different media serving software. The BluOS is what it uses.
It takes a little time to get used to as opposed to your familiar MM.
