Hi guys I too have the Schiit Mjolnir/Gungnir 2014 and Bryston BHA-1 2012. I tried A/B the best I can using the Gungnir as the dac. I tested it with my Sennheiser HD800, HD600, HD650, Audeze LCD-3, and Beyer T1. I have to say the Bryston has a slightly brighter sound than the Mjolnir. It pairs really good with my LCD-3, Hd 600, and Hd650. I didn't like it so much with my hd800. There were times I had to go back and forth many times to really hear a difference. In my opinion, these are minor differences but audiophiles pay thousands upon thousand to get that small amount of increase in fidelity. I'm not saying which one is better. I think these are both great amps. I do wish the Mjolnir offer a unbalanced connection too then this would be the obvious choice for me. Best bang for the dollar. One thing that I did notice when auditioning with my LCD-3 was the Mjolnir sound seemed more focused in the center of your head, while the Bryston less centered and more like listening to speakers. I don't if you guys noticed that. I almost would have to give the edge to the Bryston for pairing with darker headphones. The sibilance does stand out a little more with the Bryston but you also get a little more detail retrieval. Again I am talking faint differences where you have to sit there an do critical listening going back and forth, back and forth. I think most general consumers like myself included will be more than pleased with either or. They are both great amps!
