Good thread. I'm making my way through that T50RP thread as well in anticipation of my Fostex arriving tomorrow. Nice to have all the useful information sprinkled throughout organized in one place. 
 

 

[SLaRe]

Yeah, I´m waiting to my warranty to end so I can start modding them

 

[200poundsofamp]

Great stuff, haven't made it through those huge threads either. Few I've found -

Tried this one, seems like the best best if you don't have paxmate. It's impressive what just a thin piece of felt glued over the driver can do, really good isolation too.

Works best with 840 or O2 pads apparently. The leeperry mod is basically the same thing, only you leave the white felt over the driver.
 

 

[DaBomb77766]

Nice, I've gotta get a T50rp myself and try these out...anybody know the best place to get them from Canada?

 

[ardilla]

Tips/links to cables and pads that fit are also appreciated. 
 
Right now I use this, it fits and sounds way nicer than the stock cable (which broke very very fast), but since there is no angled connector, it feels dangerous, as it is sticking horizontally out from the headphone. Looks funny, though

Do you know where Fostex T50RP are still available ?

Thanks a lot, lets try this with the mods !

Why are you waiting?
Quote:

Yeah, I´m waiting to my warranty to end so I can start modding them

Quote:

Why are you waiting?


 

 
Because I have only one more month of warranty and I don´t like to mod things until the warranty has ended.
 

 

[ardilla]

^  I find that peculiar. 

 

[Lurkumaural]

^ Yeah, start now, and you can send it in if you goof.

 

[zammykoo]

Thanks for starting this thread! my t50rp is coming in the mail on monday, can't wait to mod!
