Hello all,
here is my small digital headphone-setup:
- PecanPi from OrchardAudio with Ropieee
- 2x 3-Pol XLR EP1C-cable from AudioVerse
- AudioTechnica ADX5000
Roon-Core on the ASRock BeeBox 7200U running ROCK, both powerd by HDPlex 200.
Sounds pretty good - have lot´s of fun with it 
The big headphone-setup is fully analog - sorry…
atb, Tom
