Mojo,
The AxiomAir Transformer is a music streamer and has a decent BurrBrown DAC. I believe it would be kind of similar to the Squeezebox Classic without the remote. It has an analog input and a couple of digital inputs and a single analog output.
You connect to it via the AxiomAir App. It can access flac files stored on your NAS or plugged directly into the Transformer via USB. Via the app you can also access Tidal. Spotify Connect is available via devices on the same network. I believe it can also act as a Roon endpoint but have not tried that. One of its nicest features is multiroom Spotify Connect if you have more than one for multiroom audio.
The only current feature it is lacking for me is Qobuz and I use my Squeezebox Touch for that.
Hope that helps.
