How do the modded T50RP's stack up against the Stax range, anybody got both?

Well, if you think about it. T50RP are compared against LCD2 and Stax beats the LCD2 so I would assume that STAX is better then the T50RP

I can't speak for the Rasta.. but LFF took the Paradox to a SoCal meet this weekend which some other HeadFi'ers attended:

Thanks Marv for putting this together, was great fun.
 
Didn't listen to that much:
 
AD2000: A bit disappointing to me.  I'd never heard these before and was hoping the hype from a couple of members was warranted, but they were pretty average sounding to me.  Really grainy sounding which was annoying.
 
LFF's modded T50RPs:  Highlight of the meet for me personally.  Best ortho I've ever heard, only ortho that has a good amount of air and a nice soundstage.  This sounded more like an open headphone really...it totally caught me off gaurd.  Tonal balance was fantastic, very similar to the SR009 but wasn't as refined/fast/open.  
 
LCD3: I don't have much of a reaction to this headphone.  Sounded more balanced than the LCD2rev1 I had (haven't heard rev2).  Overall good but not a giant killer by any means in my mind.  I was thinking of buying one but am no longer interested.
 
It was nice seeing all you guys, you were all fun to talk to.  Cya next time

I know LFF wouldn't post this cause he doesn't seem like a guy who's going to toot his own horn, but.. I did.  More than anything, to prove it's possible get the humble T50RP, stock cups and all, within earshot of the 009.  Which is some incredibly high praise.

Wow! the LCD3 looks freaking huge. The Stax SR009 look so sexy.

Damn I missed that post on the OC meet thread - pretty damn impressive - I will have to check back on LFF's mods (where was that mini-wiki again?)

I tried from 1 to 3 layers of 3M Transpore, 3M Micropore, and Johnson & Johnson Secure-Comfort tape on the back of the drivers after removing the stock white material. Micropore does not let enough air through and seriously muffles the sound; this was just 1 layer.
 
Edit: I tried only 1 layer of 3M Micropore tape, not 3 layers. One layer choked the drivers so I saw no reason to believe that more layers would work better than one.
 
Two layers of Transpore or two layers of Secure-Comfort tape approximates the stock white driver material. You can tune by using more (less bass-more treble) or less (more bass-less treble) of these two types of tape in various placement configurations. To my ears, Transpore provides better clarity and Secure-Comfort tape provides a warmer signature.

what's better, micropore or transpore on the back of the driver?

I also think it would be valuable to have the premod graph at least, and it would also be cool to see what effect different mods have but it will be very tedious.

Mr.Speaker those graphs (and the gumption to set up the rig) are awesome. Any chance for a measurements of a single variable in the tuning of the Fostex or a pre/post mod comparison?

I hope LFF willing to share his mods

did you try 2 layers of micropore? that's what i use. 1 layer had too much bass.

I'm starting to really like orthos The T50RP started it all and now I got the HE-4 and HE-500. I think right now the HE-500 is better on a technical level than the T50RP but it is different in signature as well as design in open vs closed. However I am quite impressed with orthos and they all sound so good.
 
I haven't used the T50RP since a few days after the RP2 was done on my T50RP but it's time to go back to it. I guess these have more potential than the RP2 so hopefully some more experimentation to get it even better can be found.

^  I removed the white driver felt/paper with nothing else added over the drivers. That produced massive boomy bass. I next put on 1 layer of Micropore covering all the driver grid spaces that muted and muffled the sound. I saw no reason to try a second layer because that would have muted and muffled the sound even more.
 
3M Transpore is sold in drug stores as "3M flexible clear" tape and it is perforated. 3M Micropore is sold as "3M gentle paper" tape and it is not perforated.  "J&J Secure-Comfort" tape is also perforated.

I've been listening to stax a little bit lately, and read N3rdling's response to hearing LFF's T50. Now this brings something to mind. How much slower are T50 Rp's decay than Stax? In other words, I THINK we've reached speeds out of these drivers nearly as fast as the STAX ~with dynamic drivers~ which suppose embody a more organic sound rather than ethereal.
 
Summarized; how much slower is the T50rp's csd charts?
 
 
 
 
*modded of course.* Care to chime in N3rdling? I noticed Tyll does not have these.

i bought transpore and put 2 layers instead of the micropore. its much more clear and bright now. dont know if i like it though, music is less relaxing than before. i prefer a dark sound signature. i will try removing 1 layer. thanks for your help

i have lamda pro and I don't listen to them anymore. Sure they have better headstage but the fostex is more "musical". Better midrange bass impact and dynamics. I need to sell my stax setup. Anyone interested?

I have one set like this:
 
1. Super mass loaded plasticine in the back of the baffles
2. Paxmate Plus in the bottom of the cups, not on the cup walls or central compartment that houses the main screw for the headband hangers
3. Stock black bass port felt uncovered
4. 2 layers of 3M flexible clear (Transpore) tape on the back of the drivers after removing the stock white driver felt
5. 1/2 inch roll of gauze 2 inches long under the back of each stock ear pad; held in place temporarily with electrical tape
 
This offers a lot of bass that does not bleed into the midrange, clear midrange vocals that are neither too forward nor too recessed, and crystal clear highs with sparkle on high hats, chimes, and bells. It's actually got too much bass for me so I tuned it down with Paxmate over 3 of the 4 bass port slots. Another bass tuning approach would be to add another 1/2 layer or full layer of Transpore tape over the back of the drivers but this might effect the mids and/or treble.  Worth a try, but I know closing 3 of 4 bass port slots works for me.
 
Keep at it until you get it to sound the way you like.

I was at the meet in OC and, IMHO, I believe LLF's head headphones were the second best headphones there.
 
1. Stax009: Which of course is the best sound I've ever heard. 
 
2. LFF T50rps: So neutral and clear with rich bass and perfect treble (for me). You have to listen to Take 5 and Amon Tobin's-Splinter Cell Soundtrack on them... mmm tasty! They sound so open, but closed!? 
 
3. Purrin's/ Anaxilus Modded HD-800: Nice rich bass with pitch perfect highs. Very close for me with LFF's T50's. Daft Punk- Tron: Legacy Sdtrk- End of Line. These headphones completely immersed me in sound.
 
4. LCD-3:  Great all around sound. Crystal clear highs and well rounded, compared to muddled highs of the LCD-2's.
 
5. LFF's HP-1000's / Stax-007: What can I say, 5k plus of delicious sound. Massive Attack- Mezzanine reminded me of the concert of last year in LA.
 
6. AKG-1000's: The best, ugliest headphone that I have ever heard, and still want!
 
LFF's T50rp's will be my next headphone purchase hands down. For the money LFF has everything thing I review beat by a mile. I got an half hour with them and boy did they impress. Wish more people could have experience them, they were a real treat to listen to.
 
Let me state that I like a neutral headphone.
