Of course, I do not own KEMAR or even artifical ear with trustworthy mic's.
I have different revisions of, hmm, kg926 based phones (I owned, many, if not all, revisions, from the first that shined with C.E.C. CD and almost failed with cheap portables).
What I'd wrtten before - in the way I've used to use phones, 11'ths tend to overexaggorate (too loud) sounds in ~5-7 (8) kHz interval. If technitiansa at Klipsch made KEMAR (or similar stand) measurements, and had results, I would be glad if they shared )
I must state, that overall sound resolution is improved considerably, even with double flanges, that's a win! But with some tracks, some hardware settings, (and with my sony mini HiFi HP out) I got high frequency artifacts.
That is why I asked about measurements, to understand, do my observations differ from them.
BTW, I think I've understood, what way I should amplify sound to obtain good results.
And I have a recommendation. The way the flanges are placed on the phones are unnatural. Right should be rotated CW 45 degr, and left - 45 degr CCW, by default.
