I've been using this for several weeks now - the engineering and parts and sound are of extremely high quality! At the Massdrop price, I (with my limited familiarity with DACs) am not aware of any other DAC that can match it. I had read a review on the internet that was not enthusiastic, and I strongly believe that review is complete nonsense and consequently I will never read another by that reviewer ("he who shall not be named" i.e. Voldemort). If you buy, check out the internal components and design (without voiding the warranty) and you will see that even inside, the craftmanship shines.
