Just listened to some Fostex T50RPs today... WOW!

[mrspeakers]

Yah, I played with stuffed 840 pads and other than a few small strips of paxmate under the back of the pad, left mine alone.  Too much pad stuffing is bad for the bass on these.  Your config is almost the same except for the tape on the center of the driver.  The reflect dot gives about a 1-3 dB rise between 3K and 15K, which to me sounds flatter, but per your taste, you did exactly the right mod...

Well, pretty much.  But I am unsure the effects of having paxmate vs. silverstone, or rubbery reflex dot vs. felt reflex dot is.
 
Also, forgot to mention, I ripped out that cloth/foam cover from the 840 pads.

So basically the pads is what make the difference in your mods?

I received this stuff today. It works well and easily for stripped headband hanger threads; just need one piece of this material inserted in the plastic receivers. It's more difficult for the 4 cup receiver threads. You have to cut very, very thin slivers of this metallic material, but it does work.
 
I think when I'm really absolutely, positively "done" with tweaking, I will use epoxy "spot welds" to hold the baffles securely to the cups.

I ordered some of this to repair stripped threads:

I'll post the results sometime next week.

mrspeakers, you really did some nice work with the RP2. I got mine out after using the HE-500 and HE-300 only for weeks and even right after using the HE500 they sound very good. I definitely have to say that the T50RP modded is my top value in audio purchases. Something that costs $200 including mod materials and pads should not sound this good.

Good point!

I'm curious - what do you guys think of the theoretical limitations of the stock baffles (which can be loaded with mass) vs DIY MDF or hard wood ones? I'm in the process of trying some different baffle types with my Dad. For a loudspeaker I can imagine the baffle vibrating quite a bit, but I'm really unsure about how stiff a headphone baffle needs to be.
 
What wins. Plastic + putty (less stiff, heavier) or MDF/solid wood?
 
Keep in mind that weight is an issue, but so is the hassle of recessing the drivers.

There is hope. I've joined 2 self-help groups...AA...Audiophiles Anonymous, and MA...Modders Anonymous.  It's been 2 days since my last mod.

when you get the newplast, the prophecy will be following its natural path eventually ^^

Although secretly, the AA and MA were formed by other modders solely to horde all the scarce resources for themselves...

Hey guys, one final question really before i decide to buy these and go to town. Whats the main differences in sound between the different mod versions?  Like rastapants vs BMF 6.3 or smeggys setup? Which sounds best or is suited for certain purposes?

 

[AnotherN00b]

lol, I don't think there will ever be any consensus here but almost all approaches attempt to make the sound as neutral, or "flat", as possible. Apart from Smeggy's thunderpants which is a driver transplant into custom built wooden cups, the mods are more similar than different and each allows personal variation to tune the treble and bass to your own preferences. The true Rastants v2 requires more expensive pads (the $150+ Stax O2 leather pads vs. $20 Shure 840 pleather pads) and the (likely) irreversable replacement of stock backing on the driver. There is a BMF variation that uses the $20 840 pads and is completely reversable so you might want to at least give that a try before going for the rastapants though many have been very happy with their rastapants. Both of these mods are still under development and testing so stay tuned!!
