Hi Tony,
No that is not it.
The file wasn't there in the beginning, and was put there by Puremusic only after I had been trying tp play the USB because of the Bryston playing it mixedup. I can delete it without a different outcome.
With the file, Audirvana still plays it all correctly, as does my mac, Itunes or my NA7004 for that matter.
grts,
Marius
