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

Here's another idea I wish I had thought about earlier. This could work to prevent stripping the threads on the two headband hanger receivers labeled "Ref. # 5 - 'Connector B' on the T50RP Parts List and Exploded View". I can post a picture if anyone is interested.
 
I bought some velcro "belts" at Home Depot to secure instruments and HAM radio wires to my hang glider control frame. They are about 6 inches long, 1/2 inch wide, pointed at one end and square at the other with a slit to accept the pointed end. You could use one of these wrapped around the headband hanger assembly instead of using the stock mounting  screw. It would be a cinch to cinch it down snuggly, avoid stripping the receiver threads, and speed up the process of making multiple, serial mod variations.

To fix stripped plastic threads in the headband hanger receiver: This is a ~ 1/2 inch piece of plastic bag produce wire tie with blue /white plastic. I bent it into a horseshoe shape and hung it over the lip of the headband hanger receiver. Insert it onto the headband and tighten the screw.
 
 

 
This shows the produce rubber band holding the cups and baffles together. This makes changing out mods faster and avoids stripping the threads of the 4 cup receiver compartments. The skinny blue object to the right is a produce wire tie encased in blue/white plastic sheath. Leave the plastic sheath on for the headband hanger. An X-acto knife can be used to remove the plastic sheath for bare wire insertion into stripped cup receiver threads.

Very happy to see you actively participating on this thread again LFF!
 
I had a dream last night that there were a group of head-fiers hanging out at some coffee house/bar (headphone club?) and I overheard you talking to one of your minions (lol) about the "secret sauce." Turns out it was Pokeman! (a small stuffed Pokeman figure crammed in the cups I guess). Anyway, you decided to take pity on me and help me with my mods so I went shopping with you and your possy! Very very strange since I don't ever hang out at coffee houses/bars anymore and I know nothing at all about Pokeman other than he/it exists (way after my time).
 
So I'm guessing that this is probably incorrect. But I might as well hazard a guess: since you said cotton + dryer sheets was close but no cigar, I am going to guess that the secret sauce is just dryer sheets (e.g. bounce) since you actually mentioned those way back in this thread? Perhaps the Paradox and CottonDryers use different amounts of this secret sauce along with other tuning? Perhaps part of the paradox is that they produce the opposite effect than anticipated (less vs. more)? Just a stab in the dark. I'm guessing that the Fischer 003 pads have as much to do with the sound as anything and there's no way I'm going to be able to pull off the FA003 sock mod!
 
Thanks for humoring me!

Thanks for the advice on the amps for T50. Looks like O2 is recommended by a lot of people.

NFB12, best DAC for less than $500, amp section better than O2, $240 shipped. Don't have to assemble...duh...

One more differences from RP2i (I think) is that MrSpeakers cover the breathing hole from the ear-side baffle with Paxmate. So it's seal.

Thanks hans and mrspeakers for your replies. Last night, i tried the rp2i with shure 840 pad with the vent closed 3 slot inside with paxmate and 3 slot closed outside with tape and it sound very well but bass is quite bloated. After that, i tried hans config with the felt ( my felt is 100% wool, about 2.5mm thick), the bass port like the previous config and this time, i feel like it lacking the very deep bass. So in my experience is the more i open bass vent, the more bass i get and the more i close the bass vent outside, the more mid bass is  tamed. So i tried this: cover 2 bass slot inside with paxmate and close 3 slot outside with tape and now it's well balance, the bass is deep and tight without bloated. I was wondering is there any mod that get the mid really really foward because using the pad riser which was introduce by HDman, i get very good seal so the bass but midrange is too recessed.
Here are pictures of my config ( this is the previous config so bass vent was closed 1 slot)

I was under the impression that the hole was left open. Either way, it's open on mine.

i just got my shure 840 pads in. they looked and felt nice but you guys did not tell me how much pain the ass these things were to get on. i had to man handle these on. lucky i didn't rip them. i had lot less issue when i was using my 240 pads.

EDIT: seems worth the pain and effort cause so far they sound insanely good. the foam used for the pads seems perfect as well. i tried the foam discs from my 240DF's in them and it seem to give them more bass impact presence but sacrificing bit of clarity. without the foam discs clarity jumped but the bit extra(not by much) bass impact presence disappeared. the foam is very very thin on the shure pads but i kinda wish it wasn't sewed in. it would made it hell lot easier getting the pads on. that's the only complaint i have with the shure pads. wish it had a removable foam disc instead. i think i might tape the outside or add bit of super glue on the edges outside cause it seems these pads can easily slide off.

It's a lot easier if you fold the "flaps" back over the side of the ear pads (kind of like you're turning them inside out?), place the pads on the headphones, and then roll the flaps over the cups. You'll also want to hold the flaps in place once you start rolling them on.

dang it...why didn't i think of that.. great idea. thanks for the advice!

just tiny bit of fiber glass or mineral wool will do the trick

Here's a picture of velcro straps used for holding the headband hanger together. Using velcro instead of the attachment screw avoids stripping the receiver threads when making numerous modifications. I bought the velcro at Home Depot and it can be cut to the length you need.

 

Vegetable produce rubber bands can be used to hold the baffles to the cups and prevent stripping the 4 baffle-to-cup threads. This photo shows only 1 in place but I typically use 2. The seal is good and further improved by adding Paxmate (or similar acoustic foam) to the cup outer rims. The blue rubber band is 9mm wide and ~ 4 cm looped and unstretched. I got them for free by buying green veggies.

RP2i at least has some measurements behind it, so it's not entirely based on subjective opinions. Not sure if that is something that you're concerned about or not. Personally, though, I'd recommend sticking with reversible mods if at all possible before moving on to permanent mods (such as removing the stock paper behind the drivers).
