UPDATE:
My new HD-800 came in flawless condition coming from Sennheiser. Sennheiser also came through with the in ears sending me a NEW pair of IE-60s!!! Could not have asked for any better service. Thanks Sennheiser!

Nice! Congrats. :) Those things are amazing.
Just to report, I finally gave up on my HD800s I bought 2 years ago ( sold them a while back because I thought the highs were too aggressive and fatiguing about two thirds of the time, serial #11XXX I think) and got a new pair serial # 153XX and on initial testing sounds definitely less stinging/piercing/tipped up in the highs, and as a bonus the bass seems more transparent and there is more of it.
Now they sound crisp and extended, but not painful, and just barely annoying on a few tracks, say 15% of the time. These are not 650s or 600s, but they are now fine I'd say right out of the box.
I actually think the highs are about the same as my LCD3s, which were recently RMA'd to Audeze for new transducers. Now it is a close contest between the Senns and the Audezes.
So something has really changed for the better. Just using the stock cord on the Senns, which seems fine. (Using a Q-cable on the LCD3s, much more coherent and focused w/o changing the frequency response than the Audeze stock cord, which I don't like.)
I let them burn in all day and now they are even warmer, and to me that's a good thing, so these 800s now have very fine tonality, with no fatigue (at least on the couple of CDs I have tried).
These 800s are just plain better, a lot better, than my former pair.

I'm glad you're liking your current pair, but just to clarify, if you bought your former 800s over two years ago, I highly doubt they were in the 11,000 range. Did you mean 1000? That would jive a lot better with your story (and sound descriptions).
Yeah, that was probably a typo by rgs9200m as I used a HD-800 that was bought near launch here in Singapore and the serial number was only 2xxx
You are right, I did forget my older 2 year old serial # and and it was just a 4-digit #; I actually posted it in an old thread I started about a year ago about differences in HD800 samples. I could dig it up if I had to.
However I think though that we have enough reports of this on the forum to suspect otherwise!
Sennheiser's own graphs show otherwise (refer to the freq certificate thread). Disappointing that this rep isn't aware of his own company's measurements.
Also not true. Past SN2000, they've all been pretty much the same, save for normal production variances.
Curious...what don't you like about the 007? To keep this on topic, maybe you can include the 800s as a reference point.
It's unfortunate I've never had a chance to own the mk1. I loved them when I heard them at a meet, but I give very little credence to meet/store impressions. They have a rabid following, and I can see why.
