I’m a new user of Glider, and indeed IOS. I perhaps have a suggestion for the DSD library issue. I’m currently playing a DSF file, via Glider, from my Chord Poly’s SD card. Sounding great and corresponding light on MOJO, confirms DSD. I’ve also got an Android phone, which runs Bubble UPnP. Bubble doesn’t show DSD files in the ‘album’ or ‘artist’ folders, but does have a separate option, in which to view all files on the SD card, so I can play them from there. This has been working well for me, so perhaps this would be an option, of which to make available for Glider in the future?
