The OPPO 205 functions - via USB and wifi - as a full Roon endpoint (rendering and decoding). wifi works flawlessly, if you have a good home wifi system (Linksys Velop, Google mesh, ...). If you replace the SONOS with a Roon Nucleus (or download Roon on a MacBook), you should be able to consolidate all your sources (stored and streamed) - except Spotify - on one very powerful streamer platform (Roon) with excellent user interface and use the OPPO as DAC.
If desired, Roon supports multi-room functionality as well.
This configuration supports hi rez and MQA as well.
I have compared the OPPO extensively to a number of other DACs (Mytek, Cambridge 840, DSpeaker X4) and think it is as good as all these very good DACs. When carefully matched for volume, none of my audiophile friends could tell them apart from each other reliably.
