Hello, I too changed to AES from USB out of my Grimm MU1 and it is better! I am very interested in the N30, waiting on its certification as a Roon endpoint. I want to run Roon Core on my Grimm MU1 in my second system, and then possibly use the N30 as streamer in my best system. I understand Roon may not be best sound quality, but I do enjoy its music selections. I have modded my MU1 with a new ethernet cable inside it, replacing the stock generic 1 foot cable. It makes a big difference. Even so much so, that running roon core on this MU1 and then using the Tambaqui internal streamer (bridge) now sounds much better in the second system, even without a dedicated streamer!
