Dre makes his music go through a V shaped mastering in order to compensate for the crappy equipment it will be played on, and you can rest assured that he has had nothing to do w/ the beats whatsoever....he simply sold his name for megabucks, and he's gotten so greedy lately(prolly didn't ask enough in the first place?

) that Monster are dropping him FWIR.

Ahem ... you forgot to mention the battery requirement for the Beats, too.

I've heard acoustic foam anywhere in the interior of the cups outside the middle of the square is completely useless and only muffles the sound?

Not in my experience.  
 
I can totally measure and hear the benefits.  And I have one "reversible" setup with fully foamed rear cups that is a bit hot above 5K still.  So maybe this is true for some specific designs, but it's not a rule of thumb.

I've also experienced this same issue.  I ended up lining the whole cup at first and didn't like what it did to the sound with so much Silverstone in there.  I then backed things out and only placed it on the bottom, flat section of the cup itself.  Much improved sound.

Any chance you'd be willing to post measurements that show how each individual mod changes the sound (or, in this case, difference amounts of acoustic foam in the cups)? I think it would be awesome and helpful to have that sort of hard data on what each mod really does. I know this won't always show how two or more mods will work together, but it provides useful information in its own right.

I'm looking to do just that over the next few weeks.

I posted some pics of a stock waterfall, then adding just cotton, then cotton and foam. You could see cotton fixed a few problems, but the combo did way more..,,

I just picked up a pair of LCD-2 rev2 last night and must have really screwed up my mods on the t50rp lol, cause they don't sound anything like the Audeze

Every mod I have tried so far hasn't even surpassed the hd650's.

You're such a heartbreaker.

Edit: stupid post

The Audeze's have a lot of variation, so I don't think they're a good reference to use like this.

They can sound better, but it's DYI, guys, so YMWV.  
 
For any source, I always will take the Rastapants over my 650s, and for most material I prefer the them to the LCD2, though there are some recordings when the LCD2 sounds better to me.  This is kind of why I went on a test vs. pure ear rant the other day.  
 
Rastapants O2 current design:

 
 
LCD2 Rev 1 (Btw, when Purrin tested this set he said it was the best result he'd seen on the LCD2s to date):

 
And the HD650:

 
The 650's bass is not as powerful as the Rastapants, though it appears it from the charts, and the 650s mids from 1-5K seem over the top, and sound artificially forward relative to the Rastapants or the LCD2.  Also, you can see that below 100Hz, there's more distortion on the 650s than the orthos.  The LCD2 and 650 are both a bit flatter in frequency response than the Rastapants, but that's because they are open and there are no back waves or other issue to address.  However, as open devices all ambient noise intrudes, so this is a bit of a red-herring.  
 
Interestingly, the Rastapants kind of falls tonally between the 650 and the LCD2, and maybe that is why I like it so much.  Like the 650 it has the bass slam from 50-200Hz that gives heft to the lows that I love, and while it doesn't go quite as low as the LCD2 in practice I seldom notice the absence because it still has real output to near 20Hz.  In the mids and highs, the curve is closer to the LCD2, and it really offers the same clarity and ease.  From a transient response perspective, the Rastapants generally is faster than the LCD2 in the mids, and both the orthos are faster than the 650.
