I have the new Lumin U2 mini just to stream music into my dac (Esoteric K-03XD), I also upgraded the Lumin power supply by incorporating a PSU made by "Jay Audio", they called it another name, the sound improvement was tremendous. I love it. And that Lumin U2 is awesome. Very stable connectivity. Very good software for music. As for streaming Tidal, I am using Tidal itself not via Lumin app. I even unsubscribed Roon once I got it. The sound quality from the Lumin is better than from Roon in my system. And I am using a NAS to store music.
