Hi Damien,
I'm using a TeraDAC USB to SPDIF converter off an iMac, which feeds a Lavry DA10 DAC.
With the recent, latest version of Audirvana, I hear faint spitting/popping noises on quiet passages. This was not happening with the previous version. I've tried changing all available settings, to no avail.
Straight iTunes sounds inferior, but no spitting noises.
Any ideas?
John.
