I would like to do measurements but currently a KEMAR or HATS with appropriate couplers and analyzer is just way out of budget. And even when you have it, it is only really good for comparative studies as there there is no rock solid correlation between measurement results and what the user experiences, especially the high frequencies response is hard to capture correctly. On top of that with super aural headphones you have a lot of noise from position, cup to head seal, distance from driver to ear etc.
Inner Fidelity is great as Tyll has measured pretty much all interesting headphones in the world on the same setup. His measurement setup and method is the best there is and while we could probably buy the same gear I doubt that we will ever reach the same proficiency in headphone measurements that he has.
