I'm thinking DSD 256 MCH might be too much to process for the Marantz. I only have SACD rips which are DSD 64 files in DSF which is a DOP format. The Marantz reports it as PCM at the input and a rather high sampling rate at 176.4khz for such file. Interestingly MrMC reports it at 352.8khz fs. I don't have any files that is higher than DSD 64 so I can't be sure what causing issues with your set up.Only regarding Multi-Channel DSD files, do you think "DSD over PCM" feature is the reason for this? Those streamers can not play DSD files natively, so the file is passed on as PCM to my receiver.
