^ I haven't used JRiver and based on a little use with Windows Media Player, it can be used on its own (right-click file, Send To, Play-Fi device). fyi, the Play-Fi app supports 24/176.4 and 24/192 wav and flac. There are gaps when playing from a phone, I haven't checked from a computer, and I don't know of plans to add DSD support. Releases are ongoing - the latest changes from two days ago as shown in the Play store, noting that this app release also updates the hardware:
- Spotify Multi-Room! You can now create Spotify groups of multiple speakers within the DTS Play-Fi app, which can be selected in the Spotify app for playback.
- Hardware volume controls can be used on lock screen (Android Lollipop user only).
- Additional streaming and playback improvements.
The most important noise floor is in your head. Always remember to protect your hearing.
