@rsf507, I like the Bricasti M21 DAC, including the MDx board upgrade, because it has the delta sigma and ladder DAC for PCM conversion. I like it fully differential design and its 'awesome' sound quality in my system.
Perviously, I owned the Bricasti M1SE DAC and I believe the M21 sounds substantially better. I use the ladder DAC setting but do switch back and forth. I have both the Audience Au24 SE+ USB Cable and the Kubala-Sosna Emotion AES/EBU cable, Balanced XLR connected to my M21 DAC from my Aurender N10 Server but use the K-S AES/EBU cable most of the time. It sounds slightly better to my ears.
I also have the Bricasti M3 DAC in my home theatre 2-channel system and it is also excellent.
