Reviving this thread again.
Assuming that NAD adds DSD capability to the M51, will it be possible stream SACDs DSD "out" through HDMI from an Oppo BDP 105 to HDMI "in" on the NAD? What chip is NAD using currently in the M51? Will the "out" from Oppo be native DSD and not conversion to PCM while sending it through HDMI?
