I think the Lumin sounds better than many outboard DAC. The Bricasti is a great sounding DAC, no doubts in this camp.
However, I have heard it with a MAC mini setup, Esoteric SACD, and the Aurender N100 Network Streamer. The Lumin sounds better than the MAC mini, Esoteric & Bricasti - - - and is on par with the Aurender & Bricasti. If you did not know, the Aurender requires an outboard DAC, the Lumin does not.
