HI screamer. I don't have the Digi models so would not be able to speak about that. Would be very interested of any blind A/B testing results you may have. Of course for this post, I was just looking at ethernet streaming to the DAC. For the most part, I have not used SPDIF of any sort other than as convenience (like TosLink out from my TV) for years on the audio side. Objrctively, coax and TosLink have more objective jitter and I find USB more consistent from a sound quality perspective. This is why I've measured USB or ethernet more over the last few years and used USB for playback where available. Of course that's not to say I believe I can clearly hear a difference...
