Thanks for the link, Sinocelt. I too missed it earlier.
I have to say that I'm rather sceptical about comparing headphones in this way. I'd agree with the comment below from this SS YouTube comparison:-

'They sound totally different in person...what you're hearing is your own headphones when listening to this video, I don't know why this has to be said and why people don't get it themselves. These videos are very deceiving, because they don't tell you at all how these headphones actually sound. You can't reproduce the soundstage, clarity, resolution, detail, frequency balance, etc. while recording, first of all because the microphones used aren't capable of reaching the sound quality level that these headphones reproduce, and second, because what you're hearing goes trough several compression processes and trough you own sound system. I can listen to my T1's with my high end setup, and T1's in this video don't sound anywhere near as good. All the headphones they record end up sounding like 50 dollar headphones.'
In addition, presumably all of the headphones are amped in the same way. That, especially with the high-end headphones in this comparison, is bound to favour some headphones whilst giving additional colouration to some others.
I also listened to the microphone test which included the Neumann U87. Although it sounded good in some ways it sounded thin and coloured compared to the other three, much cheaper, mics. Clearly the U87 cannot be worse than the other mics (unless countless studios and recording engineers have got it wrong), so evidently these 'comparisons' are not telling the whole story. In all fairness to SS they do say that the particular application of the mics is important(!).
