then i do not understand your statement about lively sound with hard to drive phones....that's a mjolnir quality, not gungnir's...
you should hook up both dacs to the Mjolnir and make a comparation
That's is indeed the sound comparison when trying each DAC hooked up to the MJ2 amp. But the Mojo is not really designed to be used this way permanently so not really a good comparison. It works in a pinch, but not an ideal setup.
