According to the specs, the RW-800 should support DSD128.
What I’ve seen (RW-800 connected through USB to different Rose streamers):
- in Roon you can only set PCM until 384 kHz. If you try to play DSD, it will converted to PCM.
- using BubbleUpnp with DSD: If you don’t set resampling to PCM, play will stopped
- using directly in the Rose Air app something like MinimServer and try to play here DSD: Play will stopped like above.
So for me this means: No DSD support at all.
