I think it depends on how you perceive treble. My HD800 have a serial in the 600's and I have zero issues with them without any excessive sibilance, harshness, etc.

 
I would agree - my serial number is 1300 and was the very first pair sold in the UK.
 
I have never had any issues with treble and only find them accurate and revealing.

I never had any issues with treble either, HE-4 are brighter than HD800 and HE-4 are actually my fav pair of headphones.

Would you say the higher serial HD 800 sounds 'better' than the lower serial model you had? 

Yes, the 13xxx is absolutely "better" in many aspects (highs and bass) and not worse in any. A great, great headphone now, and roughly on par (although different) than Stax 009s, believe it or not.

My 800 serial is in the mid 13000s and the difference is striking compared to my original one 2-3 yrs ago (900 I think).

Surely you cannot possibly compare a headphone you heard 2-3 years ago with one you are currently listening to?

I am sceptical as well. I had HE-500 loaner and the one I bought 6 months later sounded different from what I remember.
Edit: What I forgot to say is I thought it sounded different but it is not

I agree. That is simply impossible.

Unless you have them sitting next to each other at the same volume, you cannot make accurate comparisons, especially because the differences are not going to be very large.

I got the HD800s a few weeks ago and listened to them for a few hours and was very disappointed. I had two weeks to return them (or so I thought) and I only listened to them from time to time to see if I liked them better but I mainly listened to my HE-500s. 
 
After two weeks I contacted the seller and he told me I couldn't return them. I had completely misread the return policy on their website. 
 
However, after he told me I couldn't return them I started listening to them more and more, and, surely, I started to like them more and more. 
 
I went away for a week to visit my parents in another country and could only bring my Fiio E10 to drive them. It was far from perfect, but it made me fall in love with these headphones. 
 
I got back today and got to listen to them through my Lyr again, magical! I put my HE-500s on, and to be honest, I much prefer the HD800s now. I doubt my HE-500 will get much head time at all. 
 
It's very hard for me to describe the differences since English is my third language and my audio-related vocabulary is very limited but the HD800 is just so much clearer. The detail and the soundstage are simply spectacular. I just feel so much closer to the singer with these on. Voices aren't so distant anymore. 
 
Also, I mentioned that I thought the HD800 was lacking bass the other day. Now I think that all the headphones/IEMs I've tried have way too much bass. One exception though: for techno and music like that, the HD800s aren't ideal, but I don't listen to that stuff too much anyways so I don't mind. 
 
Anyways, I'm glad I couldn't return these headphones.

Is there a way to transplant LCD2/LCD3's midrange into these phones? Cause that would be the perfect phone for me.

Which one?  I'd take the 800 mids they way I hear them over most of the LCDs I've heard.  Never found LCD mids to be all that special tbh.

Hi guys, just thinking about a headphone amp for the HD 800 and considering the Schiit Asgard. Anyone here heard that combo?

 

[Maxvla]

I haven't heard it, but something tells me that won't be the best pairing, but for $250 you get what you pay for, a solid amp that does a decent job. (and I'm not being price elitist, just that combo doesn't seem like it would be a good pairing)

I wonder which the latest serial number is.  
I've got a new pair last week and S/N is 131xx.    That means there are ~14000 of these pairs  and  ~4500 were produced annualy since 2009.

The most recent are 16xxx.

I bought mine 3 weeks ago and they were 16xxx.

Thank You for fast answers. 
 
Actually it makes sense as this source says there are 5000 of pairs per year http://www.whathifi.com/blog/sennheiser-hd800-hands-on-preview-plus-how-the-163-1000-headphones-are-built
5000 per year, so in 3+ years there are ~16000
