Again, I apologize for any confusion but isn’t the data stream from a Roon core to a streamer (or dac) a digital data stream? And if it is, isn’t that a potential source of jitter? You’re right that the link I included had a different setup from yours, but the point was that the data stream from the Nucleus included jitter, but at a substantially lower level than if a pc (e.g., a Mac Mini) had been used. And that is completely consistent with a huge number of comments I’ve read from Roon users, and I believe Roon itself - that they hear a “substantial” improvement in sound quality between using Roon on a pc vs a dedicated core (e.g., Nucleus, or, in my case, a Small Green Computer).
In summary, I was trying to (gently) suggest that perhaps your test between Auralic and Roon was a test where the Roon side was decidedly suboptimal. No offense intended, and of course, I could be completely misguided.
