Hifiduino-BII-Musiland in Japan…
Atsukita blog describes hacking a Musiland 03US for the I2S and feeding a BII controlled by an Arduino.
I like the use of a modular connector and using the aperture of the MULINK connector (which is not very useful for non Musiland DACs)
Here is the DAC playing 192K material over I2S:
Notice that the best DPLL setting for 192KHz is “medium”
