I agree with the comments on the soundstage somewhat, but I don't think it's that bad. That review manages to be positive it seems despite a few negatives.
Surprised he seemed to like the Asgard a bit more than the Micro Amp. Maybe Schiit made some revisions to make it sound better with the K702.
IMO the Asgard was a poor match for the K702, but sounded great with the HD-600 (and D2000). Upgraded to this Micro Amp only because of trying to find something that played well with BOTH my K702 and HD-650.
My Asgard I had didn't seem very powerful and it just feels weird having to max out the volume just for a silly K601. Guess this doesn't mean much. I really wish I had skipped the Asgard and went with the M-Stage, but I wanted a US built product.
The massive soundstage of the Asgard with the K702 ruins the sounds IMO, but with the HD-600/650 or headphones with a smaller soundstage, it's no problem. I don't even want to know how bad the Asgard would be for the K501!
If you compare prices, the $250 seems like a better value, but IMO the Micro Amp was worth every extra penny (it's $329) and I do think you're paying a little extra for the size and build quality. Micro Amp also just seems to be a better match for more headphones.
Micro Amp seems to be just about a perfect match for the K702 and Q701. This is the main reason I bought it. Still plan on getting the M-Stage one of these days just for comparison. I bet they have so many similarities.
