Tested DSD 5.6Mhz with the Amanero board with the bit-clock reclocking mod and works perfectly. Got the sample track from Design W Sound (link in the Free Hi Res page or http://designwsound.com/dwsblog/2012/09/audiophile-jazz-prologue-part-04/). Design W Sound also has 384KHz sample tracks.
As with the DSD 2.8MHz tracks, the lower DPLL settings don’t work well (and I don’t know why as the bitclock for 2.8Hz DSD is the same as the bitclock for 44.1K PCM)
Notice the sample rate indicating 88.2K which is the DSD bit clock (5.6 MHz) divided by 64. I will change the code to correctly reflect the DSD frequency. The “DSD” indication confirms that the stream received by the DAC is DSD. This value is read from the status register of the DAC itself.
Also ignore the label “PC-LOW”. That is just the name of the input, and can be named anything. “70K” is the IIR filter for DSD and there are other values to choose from: 60K and 50K. “SLW” is the PCM FIR filter which probably does not do anything for the DSD stream.
Congrats to the Amanero team. Very nice board and nicely priced. Awaiting for version 2🙂
