For sake of clarity,Chord Mojo specifies, in its user manual, that DSD64 with DoP is possible for optical TOSLINK.
Now I can't tell if it works or not since I am not using DSD at all.
Regarding Optical transmission I will add that it:
- eliminates 100% external noises (out of computer,RF/IEM/etc...) by transport structure (optical fiber)
- lowers down computer's internal noises (Power Bus, RF,...) more or less significantly depending on implementation.
Therefore as mentionned by x RELIC x optical output is less noisy vs USB. Cheers
