Here are the two reviews from this site so far on the unit: Massdrop x Airist Audio R-2R DAC - Review & Impressions Index
@Torq does a much better job of describing what he is hearing… my review is a little rough as I am still learning how to compare, and hear the differences in DACs. But I will say this DAC was the first DAC where I actually picked up on the differences for the first time when I did the review. Also lots of pictures in both posts…I think I was still shooting with a camera phone at this point but uncertain…still learning photography too…so many hobbies so little time
