yah, USB from Mac to Mutec is how I've got it. The reset is strange. It'll start with one monitor then move to another, then the last. With each one appearing to power down and back on.
Like I said, these PMC units have been replaced twice over. And oddly enough, sometimes this occurs when I'm not playing audio but monitors are powered on and still connected to the Mutec -- but is mostly noticeable when music is playing, typically mid song.
So to answer your question, I never notice it when sample rates change.
