Since I have a new toy in AI and want to play with it, it gave the following caveat which may also explain different experiences:
if Qobuz Connect ultimately proves preferable to you, it doesn't necessarily mean Roon is "doing something wrong." It may simply mean that the Nagra's own streaming implementation is optimized to work most naturally with its native control path. That's a perfectly plausible outcome and one that's specific to your combination of hardware, software, and listening preferences—not necessarily a universal verdict on either platform.
