Looking forward to your impressions of the unit! There is definitely a bit of ground to cover, lol
That's too bad it wouldn't behave for you, hopefully, some firmware updates for the main issues at the moment aren't far away.
For the moment I do not have any real playback issues, other than the occasional audio dropout when listening using Roon. Tidal "Connect" has its issues, but reading on this subject will show that this issue is Tidal-related and not necessarily tied directly to the NS.
The Album art/Track bug is of course only annoying if you look at the screen, but it shouldn't be happening, and again only seems to be an issue with Roon, and not other modes like Spotify, or Tidal connect. Never thought I would see the day when I could say Roon has issues, it has always been my rock-solid go-to recommended software, but ever since the shift to the new 2.0 there have been some growing pains, but that version is new as well so we shall see.
If I could pick one thing it would no doubt be the software volume default, this needs to be corrected asap, while it is a fixable thing, I perceive a major difference in sound quality when it is enabled vs. None.
Hope you get things resolved quickly!
Cheers!!
