@colpgmrguy I consider the iFi streamers a bring-your-own-app streamer. iFi supports most protocols, but they notably lack the Chromecast protocol, which would be important to cast directly from Qobuz or Amazon HD apps.
On my Zen Stream, I've noticed that while casting either Spotify or Tidal (over Spotify Connect or Tidal Connect), my phone will lose connection to the streamer and I'll heard the song coming from both my stereo system and my phone. I suspect that this is the bugginess that other people experience.
On the other hand, I've had an incredible experience using Roon for years. This year, I started to use NAA, and that experience is also solid.
My recommendation is that unless you're looking to cast from Roon or use NAA, to try a different streamer brand.
