As I understand it, this player does not have a clean digit output via the usb c connector, since when connecting my dongles such as e1da 9038d, fiby fc6, jCALLY AP90, the processing is still there and it feels if you try to turn on the equalizer. The same situation applies to the hiby r2 player of the first generation, there is also a change in the equalizer and MSEB on the connected dongles. These players do not have direct digit output without processing, most likely this problem is due to the simplicity of the solutions used in operating systems. Hence the conclusion that m1s and r2 are not very good as sources for pluggable external dongles.
