Very close the same in reality.  In an extreme near-field and enclosed environment, I suspect there's not a significant sonic difference.  That's what I observe with my two pair, old and new..
 
 


I agree, they're not too much different.  My experience is that it's not the geometry, but the seal and amount of absorption/reflectivity the pads have that an change things up considerably.

Same here. However, that FR graph still has a gradual shelf of almost 10dB between 1 and 3 kHz, and nowhere is the treble higher than the 1
KHz level. Not rolled off, but far from hot in the treble.


I don't hear my new one as "hot" or "rolled off." I hear it as damn near perfect.  :)
 
 
Kinda measures that way too.  Measurements will be up soon.

Yip, that's how I personally hear it too. The reason I listen so much with the LCD-2 is they have the ideal tonal balance for me.

One of the things I've been wanting to do is make a little gray swath in the background of the graphs that roughly indicates what flat is ... but I've never really had a headphone that I think nailed it well enough to know where to draw the lines.  
 
I just might now.

Even better, IMO, would be to "zero out" the graph using the LCD-2 as flat.  Like the way you zero out a scale before using it so that you are not weighing the dirt in the unit as well as whatever item you're trying to weigh.  This way, any dips or peaks would actually be perceived deviations from a perceived flat response, and you wouldn't have to interpret them. 
 
Since some people like the DF kind of signature as well (which I find to be highly colored towards bass light and treble happy) it could also be cool to be able to calibrate a headphone's graph to various reference points.  Mr Green could zero it out using the ER4s, and see how headphones deviate from what he perceives to be flat.  Others could use the LCD-2.  Maybe the HD800 or HE6 could be another. 
 
Just something I was thinking about.  The software to make that happen might be kind of tricky.

How about putting the new pads on the old pair and check?

Nice idea!

Tyll - can you listen to a good recording of violin music or brass instrument music on the LCD-2 and another pair of high-end headphones such as the HE-6, HD800, T1, or SR-007 and compare the detail resolution?
 
Whenever I read praise here for the LCD-2, I try them again to see if I missed something last time, and I just don't get the detail on acoustic classical music that I get with other headphones as well as speakers. I don't know if it's the shelved treble or something else, but it's a very obvious deficiency based on my listening.

We're actually working on just that.

They're glued on or I would.  After I do the official listening for the review, I might give it a go.

I heard just that until I got the new ones.

What the LCD2 don't do is add an upper-trebble hump that is often mistaken for detail.

Frequency graphs only detail the intensity that the headphones produce at each frequency, not the detail, the quality or the nuance.  Although the LCD-2s likely have much less bass than, let's say, a pair of Beats, there is a world of difference in the texture and quality.
P.S.  That comparison software shouldn't be too hard.  Create a function for each headphone being compared, graph both of them over the interval between 10 hz to 20khz and find the integral of the difference between their functions.  Then you have the difference between them.

Does anyone know when the pads changed?


 
This might be helpful to you: http://www.audeze.com/2011/02/pads-frequency-response-and-other-things/
 
EDIT: Also rather than people speculating about driver changes/modifications, why doesn't someone actually ask Audeze and get confirmation either way? Personally I'd be very surprised if there had been a change.

It might, certainly.
 
Here's some pix:
 

 
 

 


Is the new one on the left or the right? I'm assuming the left but please correct me if I'm in the wrong.
