The Onkyo DP-X1 is a HIRES Audio Player with full MQA decoding capabilities (2 ESS Sabre DACS, fully balanced circuits etc), but MQA decoding is restricted to internally stored music. Neither the TIDAL App nor the ROON app can do the first MQA unfold, nor can the Onkyo hardware serve as a renderer for TIDAL-Roon-MQA files.
I think this is due to the limitations of the Android OS.
Does this also apply to other Android-driven MQA-decoders like the LG V30 and is there a timeline for a Roon update to fix it?
Android (at least the 5.1 on the DP-X1) is limited to 48kHz. Onkyo has a SDK to go around that by accessing the hardware directly (UAPP reverse-engineered this), and Roon Labs would have to integrate this into their app. Not sure if they would have an incentive to do so, even if the DP-X1 (and Pioneer siblings) are popular among audiophiles.
