Both DSD and PCM capture the same live stream from the microphone, but DSD playback is more straightforward with far less digital filtered steps involved. I have just mentioned Sony's S-Master technology in another comment, which sends DSD directly to the amplification stage without digital to analog conversion. And the output is music

If its going from dsd to a transducer and producing sound then it has done a digital to analog conversion, that basically just means you have a speaker level dac, which is admittedly quite cool. And its true that dsd is more straight forward but for a delta sigma dac that natively supports dsd the pcm playback is just fine, you aren't going to have audible loss.

Sony's method must be based on something like that: https://hackaday.com/2021/02/24/audio-out-over-a-uart-with-an-ftdi-usb-to-trs-cable/

There must be an ADC instead of a DAC and therefore DSD is treated as audio. This is definitely feasible
