I have to agree with Jason. I have my Asgard 2 paired with an Uberfrost and I'm running re-cabled DT880s to my Schiit. My DT880s used to sound thin and bright like many people suggest when they are underamped since I used to run them from a soundcard. They have much fuller mid-bass, slightly than warmer than neutral tonality, extremely detailed and well imaged highs, and plenty of air and instrument separation.
Let's just say my DT880s don't sound like the cans that they used to be. They have huge bass impact that really digs deep for a set of open cans. Asgard 2 and Uberfrost fixed all the problems that I used to have with my DT880s.
Let me remind you that I have burned them in for over 500 hours.
Thank you Jason and the rest at Schiit for bringing me an end-game solution under $1000. Truly, you must hear it to believe it before you base your options off of some people's opinions.
Noob question: What exactly does the Uber upgrade for the Bifrost do?
