We can ‘debate’ native DSD via I2S vs DoP in terms of quality differences (in the realm of DSD 64, there aren’t any!)…
Worth a read. Interesting piece on DSD and DoP - #7 by James
Before this transport exist, I rely on geerfab d.fob with a universal player (in essence a Blu-ray player) for this duty. This Onix transport doing much better job tbh.
And yes DSD output via BNC/AES and SPID/F would be DoP. No DSD output via USB.
