I wouldn't consider myself an audiophile, nor an expert on the subject. My goal was to commend Tyll on having the guts to call out what he perceives as an obvious flaw in a $4000 piece of gear. If you watch the video review he made, you can clearly see that he is not comfortable pointing out the flaw.
Most reviewers of any product tend to shy away from negative feedback for fear of blowing up their gig. I for one have never or will ever get a chance to know if it is true, but give the guy credit for calling it as he sees it, because in the end its his rep on the line.
lastly.... I am to a point in my life where it is no longer enjoyable fiddling with sliders every time a garbage recording comes my way. I do everything I can to ensure that my gear provides the type sound I enjoy and if I run across garbage recordings... they go in the bin and I move on
Just remember that one person's "flaw" does not translate into another person's perspective. The 200 ohm LCD-4s (which I will be updating my review down the road, as my initial one was for the 100 ohm initial release) are voiced with the same "pushed back treble" just as the rest of the LCD lineup; to account for the close proximity of the drivers to one's ears. And to my ears, I am quite happy with this decision. I totally respect Tyll and loved working with him in the past. Seriously folks, a 30 minute telephone call with him and you'll understand two things right off the bat: he's genuinely a very nice guy and he knows a whole lot about audio. So in the end, I strongly suggest you read several reviews to get a variety of different perspectives AND most importantly: hear them for yourself! Yes, I am a big fan of the HD800S (I bought a pair back in December and love what they can do), but I would still classify them as "brighter" sounding headphones. So this perspective from Audeze is very much welcomed to my ears.
With regards to critiquing expensive gear, I am on the record several times for stating that the even more expensive Abyss headphones (which have problematic measurement issues by the way) had significant issues for me (sonically, looks-wise, and comfort wise) and while they do some things "right", the overall presentation was too incoherent for me. But the LCD-4s, I'm a big fan of and as Tyll noted, these are the best Audeze headphone to date.
