I have 2 Yggi+ DACs. I recently got the OG because a musician guy working at Schitt told me to get the last one available and I would not be sorry. I already owned the "musical" Yggi+ Less Is More and the musician guy told me it was awful. Though I like it with my brighter Magnepan LRS+.
It took my latest edition OG about 30 days to ’work’ properly. Robert Harley’s review is exactly how it played out for me too. The only expensive DAC I could compare it was the Lumin X1 that I owned. The OG and the LIM are easily preferred. I think the neutral OG is better than the warm LIM. The new MIB that replaces the OG is supposed to be very good and sounds more like the OG than the LIM.

Another reason, I went with the Schitt DACs is that a friend of mine who is also a musician had done a project with Schitt building an amp. He told me that he had a long talk with Mike Moffat (Yggi designer) one day and came away thinking this guy is a digital genius. My friend also was not enamored with the LIM DAC. He has not heard the OG but I think he will love it with my Yamaha NS5000. He loved that speaker with the Benchmark DAC3B and the OG is a much better DAC.
I like to give preference to designers that have done DAC work for a long time. Playback Designs, Schitt, Chord, Rockna. I tried a lot of ESS chip-based DACs and while good I wanted a step up.
