Innuos Zen Mini Mk3 w/PSU |VS| Lumin U1 Mini

I can attest to the Innuos Sense 2.0.5 sounding very good, certainly better than roon (on my system).  Not full Tidal integration yet but works just fine for me and enough difference in sound that I have abandoned roon.  

I am exactly in the same decision making place.  I currently have a W4S modded Sonos Connect and am completely satisfied with the sound quality from Tidal.  But it doesnt do hires and when I stream from my CD and hires collection on a mac mini, it sounds poor in comparison.  I am looking to maintain the sound quality of my W4S modded Connect but also be able to do hires from my digitized audio collection.  It seems both the Lumin and Zen Mini can do both. Which has the better sound quality?  Also, I do digital volume control.  Can Tidal control either directly like it can teh SONOS?  Thanks in advance.

Oh, BTW, I am interested in the Zen Mk3, not the mini vs the U1 mini.

Full Tidal integration is not complete as yet on V2.0.5 of Innuos (IE: Tidal play lists shown in the same view concurrently with your ripped CD's.  I use Tidal exclusively on mine and like the interface quite a lot and of course it sounds much better than roon.  That being said, if Tidal native at present is important, I would go with Lumin. 

Thanks.  Also, for streaming hires  from a server/NAS, which sounds better, innuos or Lumin?
