Does not support HD audio
I use Plex to manage a large video and music library. Much of my music collection is 24-bit FLAC and a few SACDs ripped to .dsf. Prism down converts the HD audio to 256 MP3. No, seriously. I tried Prism because my wife was having difficulty streaming her music to our Sonos speakers. PlexAmp has a couple of extra steps, but I digress. Denon’s HEOS app slings the HD audio files to the AVR just fine, and Plex and PlexAmp play HD audio through my iPhone (with DAC and wired headphones). With Plex set to pass through and DLNA turned on, Prism is still down converting music.
