I just A/B's my Wa7's internal dac vs the my Mytek Liberty Dac, and I experienced the same thing. Now my dac isn't a Holo May, but I also heard the internal dac and felt it was a little fuzzy in comparison. It did not have the same amount of separation, so the imaging wasn't as pinpoint. However, If I didn't have the Mytek, I would probably never question using the internal dac. In fact, I was really enjoying it. I loved the sound, and honestly I felt like it synergized a little better with my speakers, which are more on the airy and agile side. However I am a sucker for detail, so I was pleased to hear the Mytek inserted into the chain.
