Better software for DSD


I have Audiovarna and when I try to play DSD files I get the music with hiss in the background. This does not happen with 24/192 files. I am using a Aesthetix Romulus player and an apple laptop computer via USB. Would JRiver or Pure Music work better?

I picked DSD over PCM Standard 1.0 as opposed to Automatic Detection. I don't see where you can pick DSD via DoP.
DOP is DSD over PCM :)

You can have a free trial demo of JRiver. See if that works for you.

I have never had any issues with DOP on any of my DACs which support DSD over PCM on USB on A+

You aren't going through an external USB-SPDIF converter, right?
