Should I build a ProtoDAC?

The FifoPi MA is a reclocker. The clocks can be easily changed. It operates in master mode like the Innomaker. The clocks in the Innomaker are soldered in place, and cannot be easily changed. The FifoPi Q7 is an I2S isolator for lower noise, a reclocker and the clocks can be easily changed. The Q7 also has FIFO memory, the MA does not.

Without a reclocker, the RPi produces the clock signal for the I2S. Jitter is higher. Subjectively, the sound is more focused with lower jitter.

There is a comparison chart of the three IC products on page 17 of the MA manual, section M.
