Here is the ( i ) help for that setting.
Native DSD: If the audio device reports that it supports Native DSD then MPD will send the unaltered DSD botstream to the device otherwose MPD will perform DSD to PCM on-the-fly conversion.
DSD over PCM (DoP): There is no way to detect if an audio device supports DoP so only enable this if you are certain that the device support it otherwise the encapsulated DSD botstream may cause loud or unpredictable distortion.
Quick test using Allo Revolution DAC
MPD set to Native DSD. The DAC's OLED display shows 2.82M DSD64.
MPD set to DoP. The DAC's OLED display shows 2.82M DoP DSD64.
If your audio device supports native DSD bitstream over the particular interface you are using to connect to it and you are seeing DSD-to-PCM conversion by MPD when its set to Native DSD then MPD/ALSA was not able to detect native DSD supported by the audio device.
