The Lumin streamer is great. The Leedh volume control on the streamer is almost as good as the volume control on my Benchmark LA4 preamp. The Leedh is not perfect at very low volume.
Lumin has a new $9k streamer that seems like the internals of the X1 DAC/streamer stripped out and the DAC part dropped. I had the X1 and I thought the streamer part was great.
If you want to save some cash get a Sonore OpticalRendu.
