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

[beckphotonik]

I have just downloaded and tried the Mozart Violin Concerto movement with no problems. I have an N1ZH60 MkII feeding a Chord DAVE. I have Twonky switched off and no MinimStreamer, I use Melco's internal DoPWav conversion. The USB cable is Chord Sarum, a notoriously poor cable for DSD.
Sorry if that puts the focus back on your kit. I have been told that Audioquest are particularly good DSD cables by the way.
