When I first saw that crazy frequency response with the massive & wide dip around 3k I thought well there's got to be something wrong with the measurements here! But then I saw the listening tests and the positive effect of EQ as well as Audeze's admission that there is a massive error around 3kHz by working with Roon to create an EQ that has a large boost in that region. I find if quite amazing the frequency response is so far off, I've seen many headphone frequency responses, and I've never seen a massive & wide dip like that in a response. So a flawed headphone, it can't be denied, an error of that magnitude in a critical section of the frequency response is not forgiveable/usable, but it's good to know that EQ can go a long way to fix it. The bass performance was impressive though in terms of very low distortion, and that Dashboard that Amir used, which we're so used to seeing in speaker reviews, was interesting to see here in the context of a headphone review (or indeed speaker review if it had been). Particularly the contrast with the Sennheiser HD650 in terms of that Dashboard and the difference in distortion as well as the visualisation of the harmonic peaks that follow the bass note.
(Not read any comments yet, just read the review, so this is just my take on it....will read them now).
