This is a kind of weird… Native DSD output from ROCK at the moment support only a limited range of DACs. You can see more on this thread where @andybob replied.
Probably I foresee this is going to be problematic in the future, only one DAC can be added one at a time; this requires software debugging and final QC. It may also need to have the hardware (DAC) for testing. By the time if that particular DAC is supported it will probably takes a long time!
DoP solves all the issues but presently it do up to DSD256, if your DAC can do DSD512, you are out of luck!
