The Yggi+ LIM is rolled off on top. It works for me on a bright setup but that was in the past so I am in the queue to convert the LIM to the MIB.
The MIB is supposed to be more like the Yggi+ OG that I also own and love. The Yggi+ OG DAC was involved in a shootout with the Chord DAVE and the Mola Mola Tambaqui using the $10k RAAL 1995 Immanis headphones. I was not there but the owner of the DAVE wrote the following:
Another Head-Fi’er, @yyzSB, sent his Schiit Audio Yggdrasil+ OG DAC with Danny, and I got a chance to listen to it not only driving my Immanis through my Zahl HM1 and VM-1a, but also through Danny’s Feliks Audio Envy. It has great tonal density—more than my Dave. And it does bass drum better than I think I’ve ever heard. Not only with the impact of the drum strikes, but the hollow reverb (I mean hollow in a good way here) of the sound of that strike bouncing around inside the drum. Timbre across the rest of the FR, and technicalities, were a touch behind my Dave, with the Yggi+ sounding a hair more digital. But the Yggi+ is also much less expensive and offers insane SQ per $.
My friend Danny whose hearing is incredible (a musician) told me that he liked the Tambaqui more, but he surprised me by saying even he would not be able to tell in a blind test.
Schitt is coming out with their FPGA Singularity DAC in 2025.
