Does anyone know if the DMP will pass DSD on the bluray sets to the DS JR with HDMI
That might be the wrong question - the DMP does pass the DSD to the Jr (and Sr) from BluRay discs, but depending on how the BluRay disc was authored the DMP may not let you navigate and play the disc… Many discs are authored assuming you can see a picture that shows you how to navigate, the DMP can’t guess the menuing structure of a disc and find the tracks that you really want to hear…
How about the Pure Audio Blu Ray discs, mainly the CSNY 1974
Some have reported that the Pure Audio Blu-Ray discs work, but I wouldn’t bank on any specific one of them working flawlessly without explicit testing. They definitely have a better chance of working than video centric discs.
