Okay, I misspoke. The Minim Server I installed on my QNAP is for streaming RP FLAC (and any radio stations). I have my radio stations saved in a playlist (.m3u) file that I access through the Naim App. And the Bubble Server I installed on my QNAP is for streaming Tidal which I control through the Kazoo app. I’m on all Mac and iOS devices here.
There’s a couple threads here that detail how to do this.
Edit - Here’s the RP FLAC file thread. Pay attention to Adrian_P’s posts.
