DA1 module MA8900, DSD

Yes, what Peter said. If you use a ROCK Core or Nucleus both of which are Linux based; then you might encounter additional issues as Linux and native DSD can be messy and complicated, and sometimes not even possible.

Really, if native DSD at high resolution is your goal, then a Windows PC running the manufacturer’s ASIO drivers are the way to go.

If you decide to go that way then there are a couple of different ways to achieve it; PM and I can go through the various options.
