I traded my Schiit Mjolnir v3 for a AsgardX with Mesh card on Saturday. I think that is the same as the Mimir. I can send you some feedback in a week or 2. I need a headphone adapter to arrive before I can listen. I never heard the Mesh card since the AsgardX was connected to the Guniger 2 and I listened to that.
BTW - the Saga 2 preamp that I had waiting for me on Sunday is really good. A steal really.
