Trouble Playing DSD128 on Melco N1Z > USB > PS Audio DirectStream

[magister]

The specs for the DS DAC say that double rate DSD is supported via DOP on all inputs (except Ethernet with the optional Bridge card which is limited to single rate), so you should be able to play the file. It seems likely there is some interaction with the Melco, which I know nothing about. I'd suggest posting the question on the PSA forum; people there are helpful and maybe somebody has experience with Melcos.
