Metronome DSS music stream server

after several years with Oralic Aries I’m considering upgrading my music server.
I was thinking about the lumim u1 mini.
but I saw on the network an interesting device from the french manufacturer Metronome - DSS streamer.
Although it looks very high quality there is not much information or reviews about it.
Has anyone experimented with this music sever?
How does it compare to lumin u1 mini, or innuos zen/zenith ?

Just looked at it. It does not even have a dedicated app. They recommend mConnect.
