Part of it I think is that I am wearing the HD800 differently now - and I believe properly. I have moved up a notch on the headband instead of riding low and the cups are placed forward. I am getting a better seal and things seem to be a bit less bright.

Oh definitely crucial. I'm at 7 clicks myself.

I have some of noob questions:

- For the purpose of reducing the HD800 highs and 6K spike, what is the difference between Anax mod vs. EQ (some pro-audio VST/AU in the music playback software)? Other than the convenience of not having to deal with the EQ, does the hardware mod allows changes that are hard/impossible to do on the EQ side?

- If a given HD800 does not show the 6K spike on the FR measurements from Sennheiser, will the Anax mod reduce the 6K spike "too much"? Just wondering here if the variance of HD800 FR might result in the mod doing unintended sonic changes.

The Anax uses a semi-porous material (rug liner lol) that also absorbs some of the soundwaves which reflect from the mesh of the cups. I believe Arnaud ran a simulation of the HD800 on HF which seemed to indicate that the 6k peak was caused by the cup design of the HD800 (the internal dimensions, shape, cavity, materials, of the cup against the head).
 
It turns out Arnaud's simulation was correct. The measurements seen here are against a block of foam. Adding the material with the consequence of aborbing a good portion the reflect waves results in a less diffuse sound. Think of it was the equivalent of putting absorb panels in room with speakers.
 
The mod results in a less diffuse stage and more precise imaging. However the mod also takes away a certain level of openness or diffuseness which isn't necessarily a bad thing. The Anax mod version 2.0 described here if implemented with the foam rings will also elevate the bass and lower mids as a result of less leakage (I run the mod with the rug liner as described here and have since eliminated the foam rings - I encourage people to experiment.)
 
I guess you could say that the mod addresses the root of the problem vs. the symptoms. Some people don't like the mod because they prefer the more diffuse open sound. It depends on the rest of the system and what recordings you listen to as well.

Curious...I'm at 5 clicks. And I don't have a small head.

I guess I don't either. ;) I count the first indent BTW.

I'm still just using "Tyll's" version of this Mod(w/ the larger ring) & no liner, as I have'nt had any success figuring out  how to get the liner to lie flat against the inside of the earcups. Actually in my setup & with any of the source material I play through them I the improvement I've noticed is very good (Maybe a tiny bit of ear fatigue after 6 hours or more; & that's only a maybe). (I don't listen to "studio recorded" or basically any "non-Acoustic" based music if that has bearing on how well the mod is working)

I'm willing to trust the"ears" here that the "Liner" version is even better, so any direction to do this version would be appreciated !  (5 clicks on the headband here also; maybe we're all clones !!! Oh no !! we may not be human)

Oh one other thing , I am using the rug liner on another set of headphones,my Hfm HE 6s. When I was regrilling the 6s I removed all the damping material from that side of the headphones . There was an increase in openness & bass response,but there was also an increase in making them sound a bit "distant". I happened to look over at the sparsely used rug liner & wondered if I changed the grille material to window screen material & attached a circle of liner to the
screen w/small pieces of breadties how this would work. I kind of like how this is starting to sound. In fact I think I'll give them a listen after I move my volume up & switch cans.
