I wonder what the difference in sound stage is attributed to. Pads?

Yes I'm sure that it's because of the new earpads.
 
These headphones are really amazing!  I have the feeling that I might like them a little bit more than my HE-560..

Thought only build material is different [as included / available pads will soon be aligned]

  When I had the PM-1, been a few weeks though, they didn't have this huge, fantastic soundstage with the velour pads.  IMO, it was muffled/veiled with a drop off on the treble.  The PM-2 with the Creatolgy foam rings in the velour pads have a very different sound to these ears.  This is not possible with the PM-2 stock pads.  The PM-2 with velour pad mod sound more like an open Alpha Dog, beats the Alpha Dog hands now, and not just in open vs closed headphones.  My PM-2 now beats the HE-560 I just sold to get them in both width and depth of soundstage.  This is my opinion, and on another setup the results may vary.  But I have tried them on my two other solid state amplifiers, and I don't lose a thing in the sound sig on them.  I am going to give this some time, but I do like it very much right now!
 
The PM-1 stock velour pads on the PM-1 did not have the air and sparkle that I am now hearing on the PM-2 with the mod that I did to them!

 
Can you post a picture of the Creatology foam or let us know the name or model number?

I purchased the creatology type foam from Michael's, picked up several different samples trying to match the material used by Mr Speakers "Dog Treats", kit that I used in my Alpha Dogs, the material I used is slightly thicker though.  I am in the process of making another set, what I have works very well, just need a little better workmanship.  I will post pictures when I get material, and cut some new ones that will fit a little tighter without glue.  It is real easy to do, just need the material and a sharp scissors, an make sure the outside diameter matches the ring on the back of the ear pad.  I made a pattern for that, but need to be more precise on the inner hole of the ring, and I may experiment with a more thin foam, shopping today, will keep you informed.  I think the foam ring that Oppo uses really kills the soundstage on the PM-1 velour pads, the foam I used allows the soundstage with the velour pads to be as wide as the PM-2 pads.  I am sure Oppo experimented a lot with the material they used, and they tried their best to please every one.  I won't say that others would have the same results that I obtained because the changes can depend on the individual gears/setup, and your ears.  I think it is worth trying though, if you don't want to worry about reversing the mod!

I have the AD and I asked Dan the kind of material he uses. He directed me to the Creatology but it i snot a foam. It is a non-adhesive felt and yes it is slightly thinker than the one he uses for the Dog Treats but it works the same. I used it inside my Audeze Vegan ear pads that I sue in my HE-6 and worked great. I got confuse because Creatology also have actual foam sheets and I though that was what you were using.
 
Here is the one Dan recommended:

And here is the foam sheets:

Your Michael's link say for 3 years old and up.....I just barely qualify then!
 
OK, that is what I used, but it is thicker than Dan's, I tried to buy sheets from him but he only has the die cut pieces designed for the Alpha Dogs.  I am going to use the extra felt pieces from my Alpha Dog kit as they will be slightly more thin.  I use on piece in each ear cup above the pad on each side for my Alpha Dogs, and it works quit nicely to smooth the treble slightly.  I use two on each side on my Ultrasone Pro 2900's plus a dual entry cable mod on those.  The Ultrason Pro 2900's have some serious bass combined with HD800 treble (as noted by many of the owners with HD800"s).  The imaging on the Pro 2900's, and the clarity and bass is some of the best I have ever heard, don't want to derail this, just stating that this felt/foam does the job with treble harshness, while not affecting the rest of the FR!
 
Here is a picture of my first attempt at cutting the foam, but I need to do a little better job the next time around, now that I know how well it makes the velour PM-1 pads sound.  I love a wide and deep soundstage!

Is it me or the PM-2 leak a little bit more sound than the PM-1 ?

I won't be terribly surprised if we have a Oppo PM-1/PM-2 tuning thread soon here.   Surprised we don't get more opinions yet on the PM-2  from the LA meet.

I guess the surprising thing to me is Oppo's decision to only include the new alternative pads with the PM-2.  Would love to know why they only chose the one pad, although there are surely many reasons (including making money selling the others).  However, including only the alternative pad is a pretty strong statement about the changes they have made.
 
Also, if everything about the driver and any damping materials is the same, it seems weird, to me at least, that suddenly the act of holding your hands over the grill is now making them sound different (whereas it made very little difference previously).  I wonder if any changes were made with the damping materials, such as behind the driver and against the grill.
 
Either way, I'm excited to hear them, although I would be leery about them if they were changing more than that, but not talking about it.

They put the drivers from their 1100 dollar premium headphone into the 700 dollar one...  That's why they didn't include the other pads as they did with the PM-1.  With the PM-1, you get the headphones and a number of extras.  With the PM-2 you get the headphone.  Extra pads aren't that much more expensive in contrast  
 
Unless the damping on the back end or plastic frame made a large difference in airflow, holding your hand behind the PM-1 and PM-2 should theoretically be the same.

Maybe no one went to the LA meet (doubt it), or they haven't found this new thread?

I was afraid this was going to happen.........I love the Oppo PM-2!

I think the PM-2 pads have increased sound stage because their pads don't have the felt rings - we're listening to the drivers through a larger diameter hole.
