I can't talk to the Gungnir, but I do have the Bifrost with the UBER upgrade - which is basically the single ended output stage from the Gungnir.
The sound is open, spacious, very detailed, dynamic, but most of all very musical.
There is a caveat - both the Gungnir and Bifrost uses the USB power from the computer to power the UCB circuits, but there is a simple solution which I have explained in this post...
Schiit Bifrost with USB & Uber upgrades
Many other USB enabled DACs also use the computers USB power - so it applies to more than the Schiit gear.
You will also find using a good quality power cable like those from AntiCables will make the Gungnir perform to it's highest level.
My Bifrost is now performing very close to my analogue rig, so I'm toying with replacing it with the Gungnir - I've heard it's a little more natural.
Others I've spoken with are very impressed with the Gungnir and if the Bifrost is anything to go by, I can see why
Good luck with your choice
