First off, welcome to the Darkside.
There are a few of us with a BlueSound device and I think most of us here are happy with the unit. The app itself is pretty crappy I think. If you are using Tidal you can use Tidal Connect to stream right to it without any loss of quality. I think Spotify Connect works the same (though is not a cd quality stream yet.) Apple music uses Airplay within the music apps, so it only streams at CD quality.
If you have a large amount of personal digital files on your computer/network, you might want to look at Roon. It integrates you local files with your Tidal/Qobuz streams (not sure if Spotify is in there yet). I have about 2000 local digital albums and I find Roon is the best player for my needs, but it is an annual license instead of a 1 time purchase.
Overall I really like my BlueSound Node 2i, and cannot imaging being without it after about 18 months. I have it plugged into a 50yr old Marantz receiver and it would wonderful.
