Plus the Mjolnir is said to be an aggressive amp -> while it could be great to give a kick to Audeze's lacking treble, the Hifiman rather need something smoother/warmer.
MLE had great results with Lyr + HE-4. Considering how close the HE-560 is to the HE-4, and the direction Schiit went with the Lyr 2 (less thick), it could be a very good match indeed.
Yes very good point.
The Mjolnir is almost too bright with the LCD-X so I'm pretty sure that it's not going to be a good match with the 560s.
