I have a ref5se and ref150, and ordered a gungnir last week. I also was looking for a balanced dac. I am using a Metrum Octave now, which I find to be excellent. For comparison, I have had a few pricy dacs in the past, and tried a Bifrost for a bit. I did like the Bifrost for several attributes, but preferred the Octave overall for its increased resolution and lack of any signature.
