Hey @edin123 check out one of my last posts in this thread. The Lumin T2 did sound better after some initial burn in and the bass had improved. I think the Lumin crew recommended at least 200 hours of burn in. I also added a sBooster power supply later on, and it seems to improve the bass further, but not drastically though.
Overall I'm very happy with the Lumin T2. I'm now waiting to see if Lumin will be updating their flagship DAC X1, perhaps a X2, in the near future. When that happens, I will consider upgrading my T2 to the latest and greatest model.
