The 6kHz peak is still a colouration whether it "bothers" you or not. It is not in the source music and that is my main issue with them. Having to purchase flawed amps that roll off the treble to account for this isn't ideal either as so many HD800 owners have done in the past (generally speaking). I don't understand why you keep brining up the number sold? I'm with you as a fan of these headphones, but I do realize that they had one serious flaw that thankfully were rectified in the S version with the Helmholtz resonator. While you mention the SR-009, you can't compare e-stats to regular headphones as the investment is VERY significant over a pair of $1300 dynamic headphones. First off, when they were released (and for a very good number of years), the SR-009s cost $5499 US PLUS you'd have to invent an equal amount in a dedicated headphone amplifier to get to hear them close to their very best. So we are talking about almost a 10X price increase. So your 5000 vs 50,000 unit comparison is roughly in the same ballpark when we factor in price. And with regards to the SR-007 MK1 (I used to own them too), they were BETTER than the newer MK2, why....let me tell you....the SR-007 MK2 had a treble peak (among other issues), that the originals did not. See a trend here? I never stated the S was better because it was released later, but that it did not have the treble peak, flaw, colouration of the original and were discontinued because the S version's sales had eclipsed the original because of that flaw that introduced a much higher emphasis on instruments in the 6kHz range that WAS NOT IN THE SOURCE MATERIAL. Thus the lack in transparency; the SR-007 did that in reverse. Please do not read things into my comments that I never inferred...it's rather frustrating to argue against a straw man. I would gladly state the opposite if the S had the peak and the originals did not (like the SR-007).
