While not exactly what you’re looking for, I upgraded from a Zenith Mk 3/Phoenix USB to an Antipodes K50 G4. In my system, with my ears, the K50 was a significant upgrade (clarity, realism, separation.) over the Innuos gear.
I also like that the Antipodes offers digital outputs other than USB, I prefer AES/EBU. The user upgradeable storage is another big plus.
I do prefer the Innuos Sense app, however, over Roon.
When I was planning my upgrade, I considered the new NG Innuos products but found their product naming to be confusing and their trade up program wasn’t very attractive.
