Yes, the Sony X800M2 Blu-ray player can play a 5.0 or 5.1 SACD, and send that as DSD or (transcoded) PCM over HDMI to a Denon AVR-X4500H. In that AVR generation, HEOS can stream over the local network several types of files, including DSD, but HEOS is limited to 2ch...can't do 5.0 or 5.1 over network. I believe the AVR-X4500H can receive a direct DSD stream from the X800M2 over HDMI. I am not sure whether HEOS can likewise do direct DSD over the network...it might be transcoding DSD to PCM even for the main zone DAC which I think is AKM4458, which can convert DSD received over HDMI. Zone2 and network DAC is likely TI PCM5100, which takes PCM but not DSD (and so would require DSD-to-PCM transcoding to play a DSD file). If anyone knows about how HEOS handles DSD in Denon AVRs, please post.
