I am seriously impressed Jerg. When I first saw your early mods (regrill and early Jergpads), I was mildly skeptical (try not to take offense). Now after trying it first hand, I apologize for doubting your efforts. I guess Purrin's measurements was the tipping point for me to actually try it with an open mind. Brilliant!

Thanks bro. As for the regrilling mod, I never mentioned but a quick and dirty way to get 80% of the effect of the mod is just to rip the fabric off the back of the stock grills. Cutting out new steel mesh to replace the grills is really quite optional in terms of sonic improvement.

Hmm, not that I doubt you or anything, but I feel quite uneasy about exposing the drivers further. I have a lot of dust in my room mostly due to carpets and because I spend most of my time on the desk moving around (even though I try to air it out at times).

However, I did try to listen to the 500s without the grills on and grill on and TBH it was difficult to hear a difference. I might be guessing but maybe a tiny bit more transparent and mildly more forward mids?

Not quite. That was actually a HE5LE mod that Dr. Fang himself proposed 3 years ago.

http://www.head-fi.org/t/491831/a-simple-way-of-adding-airiness-to-hifiman-he-5le-remove-grill-cloth

And the HE5LE reviewer over 6moons audio explained the effect fairly eloquently:

"The explanation I leave to the engineers. The results certainly take no guess work. While cosmetics do take a hit—you'll see exactly what the final photo shows which is now barely obscured by the open honeycomb pattern—those fine decay trails and reverberations that were previously obscured (killed by damping as it were) are now released. This has nothing whatsoever to do with becoming sizzly or sharp. It's all about the restored breath of life. Things which previously felt somewhat flat, reined in and muted open up. Recorded ambience deepens and with it, spaciousness. If you're careful with the removal of the cloth, it's easy enough to put back. Try and see what you prefer. To my ears, nude is definitely the way forward - and not just by a few marginal inches but significantly."

tl;dr the regrilling allows for much better plankton extraction in the sound.

this is really cool. would love to give these a listen.
not sure if you remember me jerg but I was at the montreal head-fi meet last year in august - and we just happened to live on the same street. :P (sorry for creepy)
never got to try the HE-500 with velours but I love the HE-500. I could bring my M^3 if you're interested in trying it. well mostly because I'd love to try the combo, as I'm getting a pair of HE-500... and your pads do seem promising. :D

gosh, don't be such a jerg... I mean jerk!

I assume no plans of doing this semi-commercially? I showed this to a friend who would love to try with his HE-6.

Interesting how the HE500 CSD voicing with the modded pads bear some resemblance to HE5/HE6 plots now (upper mids looks like HE5, treble looks like HE6), just with a much thicker lower end relative to the upper end levels.

After a bit more time with the Jergpads, I'm starting to become VERY curious how the V2 measures. The measurements are with the V1 pads right? Pad snipping, not the venting.

EDIT: Ignore me, just read it being V1.

Yes the pads I sent to purrin were v1, which is basically Parts I and II of the v2 guide. It did not have the velour top mod or the sub-bass mod.
