@efoo I currently have a Lumin U2 mini with an upgraded power supply. I have had the D2 and P1 as well. Also have owned an Aurilac G2 streamer. If you like the Lumin sonically, really hard to beat. They are dedicated to building streamers and Streamer / DAC combos and that’s it. The parent company is in the professional / commercial audio / video space. Great App which is really important, update and upgrade their software regularly. My U2 mini is outstanding, I would assume the U2 steps things up further. They’re all in one solutions like the T3 are really tough to beat as well. I loved both the D2, step below and P1, step above the T3.
Good Luck,
