Sorry but that’s a bit off base. “Native DSD” most often means “the original DSD bits will be handed to the next device without relying on DoP encapsulation”. That kind of native DSD playback is not commonly possible – it technically can be done with USB but you need custom drivers and custom firmware in the receiving device’s chipset, which is probably what the Aurender is attempting to do.
The only reason you’d want that is if the process of unpacking from DoP causes some kind of electrical noise in your DAC that is detrimental to the device’s overall sound quality – or if somehow your DAC didn’t support DoP at all.
The DS DAC does not support this kind of “native DSD” over USB. And that’s fine, because there is zero sonic penalty for using DoP in this DAC.
The DS DAC does support native DSD over I2S in a clever scheme where the normal data line carries one channel worth of DSD bits and the LR clock line carries the other. This has the advantage of requiring just one third of the baud rate on the data line compared to the equivalent DoP encoding.
In the end, the thing that matters most is that you see “DSD64” or “DSD128” on the DS DAC’s screen. That’s how you know your transport is successfully sending DSD.
