If you like the sound of the DAC then don't worry about a negative review or what others think.
Regarding the the review being a "hatchet job", I didn't read it that way. There was some early nitpicking about the remote and a power-up delay, but I didn't read anything I would classify as being malicious, unjustified, or irresponsible. Amir performed measurements on a brand new DAC using his test equipment. He reported the results and pointed out areas where the review sample performed well (linearity and dynamics) as well as areas where it performed poorly. He concluded that, in his opinion, a DAC in that price range should perform/measure better. He offered to revisit if the company disagrees with his results.
Maybe one problem is that we have been conditioned to expect that all reviews will be positive. Even the negative reviews are often carefully scripted so as not to offend. My problems with the "review" are that there is no mention about how it sounds, and the minor pile-on by other readers is mostly bad form. However, just because the DAC measured poorly is not a reason to discredit the messenger.
