I'm expecting it to arrive today or tomorrow. I should be able to pick it up once its here (my parents house) and bring it back to where I'm living, before the weekend.
I may not be able to do a direct comparison, but I've had the Dac3 for about 1.5 years now, so I'm fairly familiar with its sound. I figure I can at least give a ballpark comparison to differences in tonality, if nothing else.
