I have used a LUMIN D1 for 5 years - it ran flawlessly - it uses the Wolfson DAC / got constant updates on the software on the internet from LUMIN- when MQA came out my D1 could fully unfold the files at no extra cost - definitely heard an improvement in my sound. I stream Tidal HiFi . I sold the D1 5 months ago and now I run the LUMIN T2 in my main system / it runs a Sabre DAC - bigger sound stage and more detail than my D1. I just added a LUMIN D2 for my second system in the Mancave - love the LUMIN D2 - the Wolfson DAC has a warmer sound - vocals are great with the D2. Build quality on LUMIN streamer / DACs is great - software support is great - both the T2 and D2 are improving in sound as they break in.
just my 2 cents - Happy Listening!
