I dropped off my Schitt Yggi+ OG with a top end headphone vendor for him to test it out for a few weeks. He is now coming around to how incredible this DAC is. Not warm, just neutral, and relatively low cost.
Since this DAC is no longer made the replacement is the Schitt Yggi+ More Is Better (MIB). I am going to convert my Yggi+ Less Is More (LIM) to the MIB for my headphone system. My phones are extremely detailed and neutral and sounds very good on the OG. A future upgrade of the phone I have is a bit warmer. I heard it on the Yggi+ OG last week and it was stunning.
