I have the Asus Essence One Muses Edition and the Mjolnir and I was curious as well how the Gungnir would be as a DAC opposed to the Asus. Right now, it sounds good, but I'm wondering if it could be a lot better.
When I was at a meet one time, I tried the Lyr/Bifrost on the HD650 and it was a lot better than the Muses. The Muses is actually very good with the 650 but not so much with my LCD-3.
I then connected the Lyr to the Muses DAC and it wasn't anything like the Bifrost/Lyr combo on the 650. In fact, it wasn't that much different from my standard Muses edition.
That's why I have such a curiosity for how the Gungnir/Mjolnir sound as opposed to the Muses/Mjolnir sound.
Because the mojo is powerful, there is quite a dynamic, lively difference with the Muses DAC as well as it working it really hot. The bass is there but not as much slam as I was hoping for. Perhaps that is LCD-3's fault.
I live in the DC area and if there is a meet here and someone has this combo, I'll check it out and see if I should just get the Gungnir and use that exclusively with the mojo. I'll never get rid of the Muses though, it is so versatile and sweet sounding with the 650.
