If you get a chord 2go/2yu you can stream from any app on your phone that plays music/movies etc. The chord app only accesses the chord streamer for settings and connection once connected (5 seconds) you just use what ever playback app you like. for example I use it with the iPhone tidal app / Spotify / Roon app etc. I even use it with YouTube.
your just using the phone sound output sent to the chord like you would if your using apple airplay, android equivalent.
its IMO the easiest to use yet (I've used roon/aurender/blue-os), you just use the streaming services app not a propriety app form the streamer manufacturer.
granted the chord streamer is not cheep but it is portable and sound very good better then the Aurender A10 I replaced it with.
