I received my tone board the other day. Playback has been without problems and I’ve played PCM up to 384 and DSD native and DoP up to 256. However when playing DSD the channels are reversed. I have duplicated this using roon playing via multiple devices, micorendu, sotm, and windows 10. All forms of DSD from native DSD formatted files to upconverted PCM to DSD files play with the channels reversed. Hopefully they will fix with a firmware upgrade in the near future.
