Well, I will jump in on this thread. I use JRemote running on iPhone 7+. When attempting to play a DSF file on the iPhone, I get a notice that the song or album will play now, but then the Audio Streaming Error message pops up and nothing plays. Same result if playing the iso files from the same album. Of course, the 24/88.2 conversion of the DSF files plays just fine.
Are DSF/SACD iso files not supported for playback on an iPhone? Thanks. JCR
