Update: So I was finally able to get my TEAC. As per big_greg's description, the unit is a real upgrade to my node 2. I am not ready for a final verdict but the soundstage is significantly improved. I was not able yet to compare the DAC with my MarK Levinson as I need to get an additional cable but will report back when I have that info. Setup was very easy and I did not experience any hiccup.
The downside is the TEAC HR user interface as big_greg explained earlier. I did not find the Lumin app to be better and as I only use the streaming part of the app, I found the Linn Kazoo the best so far: It allows me to access playlists and is an overall better navigation tool (my opinion!). I am still puzzled that some basic functions like random title play of a playlist or an album are not available. Also: All of the apps tested do not allow to continue a playlist once you manually selected a title from the list. You either start at the beginning or you need to skip titles until you reach the desired track. Any comments or suggestions are welcome. I am very happy with the TEAC. Thanks big_greg!
