As a prior Roon user and now Audirvana, I can say that Roon’s interface is superior, but Audirvana sounds better when connected directly to a DAC via USB. Roon’s architecture is designed as client/server vs Audirvana. Given this, testing multiple end points (roonpieXL, Bryston BDP-3, NUC PC (no moving parts), etc.) vs Audirvana running on a fanless PC (like a NUC) with a audiophile USB card, separate LPS powering the USB card, Audirvana sounds better to me. All other components remained the same. I even tried other software JCAT FEMTO, Amarra, Volumio, Daphile, but none other sounded as good or had a user interface close to Roon or Audirvana that I liked. Hope this helps.
