Better software for DSD

I have not had that problem with Audirvana/MacMini.

Your DAC doesn't support DSD natively

You need to set Audirvana Plus to convert DSD to PCM.

I take it you have A+ and not the free Audirvana - which I recall does not handle DSD in any form.

Audirvana Plus/Preferences
Audio System tab
Under DSD Detection, set to None: Convert to PCM

Select Max Sample Rate to 192kHz - the maximum your DAC can handle.

See if that helps.

Doggiehowser I have the Aesthetix Romulus Signature which has dedicated DSD. Pure music may work better with the Aesthetix than audio varna I'm not sure. I could try the free download.
