I don't quite understand the whole reasoning behind analysing all these graphs and measurements, I've heard a fair number of the TOTL headphones and I can easily say that the "distortion" of some headphones and all these alother weird arbitrary tests and benchmarks mean nothing. Implying that headphone manufacturers don't know what they're doing by citing the fact that their headphone doesn't "measure " well is quite nonsensical, it's as if these audiophiles claim to know exactly how to engineer a perfect headphone...
This entire hobby is based on listening with our ears, not reading charts with our eyes. For me, the K812 Pros sound practically perfect (and will probably buy a pair in the near future) and the LCD-3s sound like a narrow congested headphone with no 3D sound stage and shelved treble, whereas according to their (arbitrary) ranking the LCDs are more fit to be a flagship headphone, because they look better on paper, rather than sound better in person.
It almost seems like these people would rather buy the headphone, put them on their head, and read a chart of how the headphones are so "technically perfect" without having them plugged in...
