Pedja has designed a board for feeding the AyaII or any TDA1541A DAC with simultaneous mode which allows the TDA1541a to receive discrete left / right data to attenuate jitter and glitch pulses. The board will be populated so it looks relatively easy for a DIY novice like me to wire up.
The board uses the XMOS USB receiver chip, isolation, dual clocks, reclocking, inverted data options for dual differential designs and looks to include firmware options for right justified output needed for the Burr Brown PCM63/1702/1704 family. The design shows the usual excellence Pedja is known for. It looks like it will be around $250 landed .
