It's understandable to be skeptical as the proof is in listening. But remember, I been at SBAF a long time and posted many headphone mods here in past. . ..no visible changes to the HD800 except for the Dekoni pads. I needed to assess long-term reliability of the mod, which is why there was no mention since the January measurements. I have successfully gained greater control in dynamic drivers in general. I am currently tuning the HD800 character, to strike a balance between agressive or more laid back, as I noted in one of my measurements (not posted). This is not simpleton mods, and it is more than frequency response, as the image is not only cleaned up, it is larger and deeper. Currently,it is now close in character to a Susvara, which is my reference headphone choice which is what I want to tune it close to.. I posted link to the REW file here, for anyone interested to go over, and it been months of crickets about it, so I took it down .
