Can we talk streamers based on UI rather then SQ?

I'm a Node 2i user currently and looking for a change.
I've been reading lots of posts for the last week or so and I'm not sure if I'm more or less confused then
when I started. Lol
Looking to move on from the Node platform because the UI is bothering me.

Most of the topic of discussions based around the multitude of streamers seems to be on SQ.
I could be off base, but I think in my mid-fi system, (Wired 4 Sound STI-500V2 >dac to be determined>Dali Helicon 800) I'll be happy with the SQ of most any streamer. I'm much more concerned with the UI as I really just want it to work as intended.

I've got about $2K to spend on a dac and or dac/streamer. 
I see a ton of praise for the Lumin gear but I also see that it seems to be built around the IOS platform and I use Android / PC. Has this issue been resolved or am I making a mountain out of a mole hill? 

I also like the idea of the Pro-Ject Stream Box S2 Ultra, just have no idea what the UI is like.
Or any small form streamer that "just works"
I like the idea of being able to DAC swap with these.  

What I want out of it:
 Streaming mainly. Tidal, Spotify and the like. 
 Ethernet Connection to my router and no issues linking to my local music files. (Node keeps dropping my local files)
 
I like the look of my Jriver index but I'm not married to it.
Don't care about Roon at this point.

I don't need a NAS do I? I have less then 1TB of music. 

What will help me make this decision? 
 
Thank you
