Marv, I still want to see the measurements from mine even though they aren't accurate with the other graphs on this site. purplegoat and I just want a direct comparison of both of our HE-6s since we were both in the same room at the same time. Actually, mostly because purplegoat has been nagging me for them. 

Thanks for posting that one. I guess it's time for Vegans.

Jason's mods are Vegans with sticky stuff (no HFM plastic ring), hardwired copper stranded cable, fuzzor mod but with soft adhesive back felt (not stiff adhesive back felt), and grill mod with cotton removed. Got the memorized at this point. 

I was thinking about selling the HE-6 but now seeing this graph I figure I should just get the vegans and do the fuzzor mod with soft felt. My big issue was the dip at 5k but Jason has fixed that.

And for those keeping score, ohhgourami's HE-6 in red:

yes. The treble got rolled on the measurement significantly. you might have the HE-6 with the smoothest / less peaky treble - and it sounds that way to me too. I do not like stock HE-6s at all.

That's the reason I like yours. As you know, my preference is "not bright".


What is the jerg felt mod? (sorry, I'm am lazy)

I don't criticize the sound for the tamed treble, I think the HE-6 is bright to a fault. I felt your HE-6 pulled me into the sound at an odd place, it might have just been because they were out of phase. I think you have the best HE-6 so far, but maybe it's just not the right headphone for me. That said, if there is supposed to be air and yours don't have it that would be an error IMO even if it's less pleasurable, but I couldn't hear well enough at the meet and I don't know well enough in general to make that assessment.
