Here is mine.

Looks a lot like mine!

Here are my results.  Powering them with a Lyr and loving it!  

  After 2 weeks the headphones have not exhibited any harsh highs and the bass is definitely not anemic.  Just the right amount of warmth and a whole lot of detail.

Here's mine... SN 29547... sure looks a lot like the one just above  SN 34364 (no I DIDN'T copy his paper!)

Here is mine, purchased in early December 2014.
 

 
Yep.

In fact, the graphics are very similar. But the sound is different in the new series. More bass, but a little less space at the same time.
I had a lots of 800 in different series, but I stopped only 38xxx.

I had a second HD 800 too, with a markedly different graph. Its sound is more inviting, probably due to the "HI" that appears in the upper frequency range of the graph.

That's what the oBravo headphones sound like. http://www.innerfidelity.com/images/ObravoHAMT1.pdf Tyll's measurements are generous to the oBravo's real sound XD

I was wondering if the ones without the 6k peak, did anybody notice a difference?  Was it less bright, more bass, compare to the older ones?  If that's the case, less reason to jump on the HD800S haha!

In my understanding, the individual HD800 frequency response graph shows the difference of the said individual unit when compared to Senn's reference FR which is this one:
 

 
So the 6k peaking will always be there, more or less. That is actually a testament of Senn's QC on HD800 drivers.
