FWIW,
I re-tested the "Less is More?" mod with different amounts of 100% cotton added to the cups ranging from 1/2 to 1 Jumbo cotton ball teased apart vs no cotton filler. To my ears, cotton added no benefits and actually muffled the sound proportional to the amount used.
You can increase the bass quantity by adding more tungsten putty. I know, it sounds counter-intuitive but that's what I hear.
The components are as follows:
1. Tungsten Putty around the driver and up to the edge of the driver perimeter, sort of like a 1/2" wall of putty. Again, add more if you want more bass.
2. Paxmate Plus in the cup bottom with the stock bass port felt in place and uncovered; and the central compartment uncovered.
3. Dynamat surrounding the driver on the ear side after first removing the dust cover and adhesive; I left the dust cover in place over the drivers.
4. Stock driver felt or 1.5 layers of Transpore over the drivers.
5. Stock ear pads with a "rope" of Kleenex rolled up and about 4 or 5 inches long, placed under the rear side of the ear pads. Shure 840 pads are optional and may change the sound.
6. Plasticine or Paxmate in the cup outer rims.
I found that tungsten putty flush mass loaded filling all the baffle compartments also works and sounds similar to the above. I medium mass loaded another set, all other things being equal, and got more bass quantity. None of these configurations caused bass bleeding into the mids and treble remained unaffected, too.
May be placebo, but I believe the combination of tungsten putty and dynamat around the ear side of the drivers improves SQ, and I like what I hear. YMMV, etc.

So I went to B&H today to pick up some Beyerdynamic pads for my HE500 and I ended up picking up a T50RP and SRH840 pads there as well. It's funny how a $30 purchase turns into a $130 or so one
Anyway I was planning on getting the latest BMF mod and I hope to do that this weekend. I have the Rastapants and one for the BMF would be good to compare just to see. I'm not sure if the latest BMF works for SRH840 pads but they probably are not too different other than stiffness and the thickness of the pads.
yeah...how do u get the srh840 pads on?
