Quite a few Bricasti M21 DACs for sale cheap

The mothership just called me back to tell me that there is a new MDX board. $800. Unclear as to whether or not it's user installed. 

Looking to go from M3 to M1S2. I don’t think I care for the new blue display and on top of it I just turn all of the displays off anyway. 
Did Joe mention any sonic improvements with the new MDX board?

@audphile1,

I also installed the Bricasti MDx upgrade board in my Bricasti M21. My system sounds clearer, smoother, more engaging with more musical details. I like it very much and also highly recommend the MDx board upgrade.

Please read the instructions carefully since it requires you disconnect some cables, remove the old board and install the new board. I had someone help me and the job took about 45 minutes (we moved very slowly).

@hgeifman thanks for this info! Very helpful!
