500+ Head-Fier
I had a bifrost uber a while back and unfortunately it was before I had the Aune S16 and the Gustard X12. My recollection was that it was very similar to the Aune. It uses the same Japanese chip for DA conversion, but an earlier model. Very smooth and musical. I thought the X12 was better than the Aune in most ways, so I sold the Aune. Based on this experience, I would probably end up giving the nod to the X12 if I were to do a head to head comparison to the Bifrost Uber.
