We are a an Aurender dealer. I have had a couple of DAC's that did not jive with the Aurender at first. However, their support team can help. Also, Aurender should be able to play DSD up to 128
Check this link out: https://ask.aurender.com/hc/en-us/articles/360026675894-How-can-I-contact-Aurender-Technical-Support to get your DAC going - they can remote in and update the 200.
Also, see this:
Aurender uses DoP (DSD over PCM) to send DSD files to DoP-compatible digital-to-analog convertors. Since DoP uses a PCM data stream, a DSD64 file will display at 176.4kHz, and a DSD128 file will display 352.8kHz on the Aurender Conductor app readout. Note that the receiving DoP-compatible DAC still reads the DSD file natively, as the PCM stream is simply acting as a transport for the original data.
