I've been listening to my 880s on an Asgard. It's a perfectly fine match. A few weeks ago, I had the chance to listen with the Valhalla and they sounded like a completely new set of headphones. It took away some of the edge and graininess and felt like a near perfect pairing. I've now got the Valhalla 2 on the top of my wishlist.
