With what company do you practice your audio engineering skills?
I did my internship at my faculty research center (I'm more involved in research work, want to starting a master's degree in psychoacoustics this year), but I am very familiar with headphone measurements with the fixtures we have here in compliance with the IEC 60318-4 (711) and 60318-1 standards; a couple of GRAS units (including a 45CC with P51 mouth simulator) and a Larson Davis AEC206 (which is very similar to the 45CA used by Amir and Jude). We even have an anechoic room where we have tested prototypes from one of the most recognized speaker brands in Mexico for third party validation purposes.
That is why I defend Amir's practices and methodology during his measurements, they are much closer to what I have seen and experienced here (and compared at other research centers) than Jude's.
How about bad seal? As an "audio engineer" you should have no problem understanding what happens to a transducer when its operated outside of its intended enclosure (or lack thereof).
You even bothered to read Amir and Jude's measurements? Both have complaining about the results due to the tricky sealing, as I do in the first point of my last post.
There are sub-200 planars that don't suffer from this problem, maybe you should demand a little more for the extra thousands of dollars you pay, but it's up to you.
If you're on the "I trust what my ears hear and what the manufacturer tells me" side of things, I don't see the need to get into discussions about technical aspects that you clearly don't understand, enjoy your Diana and let the rest of us debate about it.
