Those are indeed great results, with really low noise, but still I'm curious: Did you test to see if using the "Pure Direct" feature bypasses the digitization of analog inputs, like I believe is the case with most of their units in the past?
[In some reviews I can figure this out on my own by looking at an extended range frequency response curve that goes well beyond the audible band, due to the sampling rate limitations only found with digital, but I didn't see any such super high freq. response curves in your report. Thanks.]
