I am a happy owner of a Yggdrasil Analog 2/Gen5 USB. The Schiit multibit DACs were the first to actually sound like music to me. I had a Bifrost with two different DAC boards in it before multibit and they were fine, but di not really make me want to listen to lots of music. That changed when the multibit board was installed. I liked it so much that I bought a Yggdrasil for home and moved the Bifrost to work.
Please note that the BiFrost 2 is now out and includes the new Unison USB board. It is supposedly the equal of the exiting Gen5 Gungnir. Schiit has bought a license to develop their own USB code and by reports, it is quite an improvement over the Gen5 USB board. Upgrades to the existing Schiit DACs are supposed to become available after 1/1/2020.
If you can wait, you should audition the Gungnir and Yggdrasil with the Unison USB board. Hopefully we will also get a Schitt product with a Unison code sender USB port.
