If you mean the Massdrop x Airist Audio R-2R DAC (which, oddly enough, just started another drop), then yes I did!
Tonally they’re quite similar - including a general sense of “sweetness” to their delivery. The CYAN is definitely the more technically capable of the two units, across the board, however; and is best compared to units like the RME ADI-2 DAC, the Soekris dac1421.
