Yes, I have a whole house DTS Play-Fi audio system and its a blast to tinker with. 9.2.8 HT/immersive audio system with a Play-Fi streamer going into a Sony Signature dac connected to active Paradigm 40 speakers in the media room. The HT processor is a Marantz with Audyssey room correction (paid upgrade with calibrated mic).The HT is connected via XLR. The active speakers also have RCA on the back so flip the switch and now being driven by the Sony Signature dac via its preamp outs. The streamer has ARC room correction so now I have a two channel system completely seprate chain from the HT in the same room.
Desktop system- 2.1, Paradigm Active A2 speakers and a Klipsch Playfi integrated amp using preouts.
Back Porch/Sunroom- two active deftech W9 speakers using the built in play-fi streaming function.
Mancave- Onkyo play-fi friendly HT receiver running a 5.1.4 JBL immersive home theater.
Patio- boston acoustics outdoor speakers connected with a play-fi friendly deftech preamp and a parasound amp.
Garage- Martin Logan playfi friendly soundbar for both streaming music and connected via hdmi to the TV.
The app was glitchy years back but has been refreshed so many times now it works fine. You can also use the system with the spotify app or DLNA as well, unlike BluOs which is not DLNA friendly. I have a Bluesound Node and don’t like the fact that you can’t use DLNA in their system. I often use bubble upnp on my phone to steam from websites not in the play-fi app, NP. Sometimes I just use alexa voice control and don’t even use the app as play-fi is alexa friedly as well.
