I had only a
short hour to enjoy the fujiya-avic festival this fall but I was
blessed: anakchan and I got to spend 20-25min talking to Axel Grell, who
is actually the father of the HD800 and HD580/6x0 series among other
things. That was just awesome!
We could talk about the hd800s tuning and he repeated pretty much the words from the video (response was made a bit flatter and extended at both ends of the spectrum).
When discussing the diy mods that were done to the hd800, he actually mentioned sennheiser tried to reproduce them to see what the enthusiast were raving about. Actually, you'd be amazed how much open he was and clearly listening to the pulse of the crowd (following head-fi in particular). For the felt mod, it turns out sennheiser felt this was kind of ruining their efforts to make a resolving transducers with too much attenuation of the highs and also affecting staging because of the dissymetric absorption in the earcup.
The hd800s tuning is not your typical diy trick apparently. Axel mentionned about a tuned absorber for specific frequencies (helmholtz resonator for those who know a bit about acoustics). That was, they might have addressed the 6khz peak without killing of the upper treble (they managed to extend the highs actually).
Unfortunately, I ran out of time to try the hd800s (would be hard to comment without familiar source and music anyhow) so I will let others comment on the actual sound attributes.
We also had some conversation in regards to the manufacturing of the electrodes for the new orpheus, I will post that in the other thread I guess. That was pretty cool conversation!
The good news is that Axel seems to be back to headphone R&D even though his official role is more in marketing as I understand. He was for instance involved for both the new orpheus and hd800s projects, so a great news I think (I still think the HD800 was one of if not the most innovative phone to be released in the past decade). We briefly talked about the moderate success of the hd700, and I have a feeling Axel will get involved in its successor and/or evolution
(note: he did not say he was working on hd700 successor, that's my take from the conversation).
Cheers,
Arnaud
