Hi , I’ll try to make it quick. DAP: Pioneer XDP-100R (Android) Amp: Oppo HA-1 (usb in) If I use native Pioneer/Onkyo app I get all codecs up to dsd because the app can be set to usb output DoP. Tidal app does not offer output format to usb option, and it goes to headphone output only. Any ideas? Thanks!
