Received my Bifrost MB yesterday and left it on for about 24 hours and listening for past hour. It's really close to Gungnir MB and now I'm wondering if I overspent on the Gungnir! 95% of my music is 44/16 lossless, but even my 96/24 tracks sound nearly identical on both. I don't have a full balanced setup with Gungnir so I can only assume that's where I will hear a difference, but for SE setups the Bifrost is an absolute steal! I may change my opinion once my Liquid Carbon arrives so I can try balanced.
Overall I think the entire line of R2R DACs from Schiit are redefining the long standing advice to upgrade headphone/speakers first. Since the vast majority of music is in digital form, I think people should reconsider upgrading their DAC first, then headphones.
Very glad to hear this (and would be listening if I hadn't missed the FedEx guy). It was my plan to replace my Gungnir MB in my speaker system with this, my speaker system being single-ended throughout. It is also my plan to eventually use the Cavalli Liquid Carbon in my headphone system. I am currently using a Schiit Mjolnir.
