I have a Lumin D1, which has the same DAC as their higher end models like T1 and A1. It is an integrated music streamer with its own DAC, and accept both USB input and Ethernet from NAS drive. The streaming is through Mimimserver, and support Tidal. I have it for a couple of months and it is flawless to play all popular DSD and PCM formats. In many ways, it betters my $4000 tube CD player.
