I think the review is rubbish. I mean, just read the first paragraph of the conclusion on page 3. Utter gibberish.
I do however pay attention to the JA measurements in these reviews, and his findings of "Esoteric N-01 offers respectable measured performance" is slightly underwhelming for what I hear in my N-01, which is absolutely stunning sonically for everything that I throw at it (however I'm using an external master clock and Halcro dm-8 pre-amp).
And as for the reviewer waffling on about the freezing issue, and after blurbing all that out he ends up saying the problem has been fixed in software, I mean WTF??? Sure, onus on Esoteric to provide a functional review sample with current software, but to expend all those column inches to talk about a non-issue that doesn't exist any more is pedantic and completely needless. And on that point, I've owned my N-01 for almost a year and it has been flawless in operation, not a single instance of flaky behavior.
