^^ I agree with Joel that the O2 as good low frequency but it also have good mid and hi so a good neutral well balanced amplifier. With the gain switch option you can get enough power for the modify power hungry T50rp.

Still liking the lead tape over the Dyna/Fat mat. It sounds cleaner. O2 also sounds great with mine, but I had to do a recable to get rid of the 1/4 jack. 

Metric and tweaked RP2... Yummm. 

mmmm lead    ^

+1 for O2. 

It really is wonderful with the T50 and Q701 which are also very power hungry. I wouldn't call the T50 really hungry though, as it sounds pretty good out of most things. When I want to listen to music spread over the freq. spectrum evenly I go with the O2 over the Lyr actually. :) The O2 fed by the bifrost is pretty special imo.

Agreed.  

While I've done some "exploratory" missions on my Fostex, it will essentially be very early this week when I get the proper acoustic foam in order to proceed with the gutting and rebuilding.  I'm also going to opt for building a new, Cardas cable to feed each cup and terminate it with a 3.5mm silver connector.  I've basically tried listening a bit with the Fostex with only the mesh over the driver face removed and can't wait to move ahead further.

In regards to the cups and the cable replacement, I hope to design something a bit neater that will make them appear better where the cable connects the cups.  I also have the Objective 2 amplifier as well as the C&C BH portable amplifier.  One thing I've noticed so far is that the C&C does some coloration of the upper frequencies with the sound on the Fostex headphones.  However, this wasn't the case with my Magnums, where it was harder to tell the difference between the O2 and the C&C - though the difference could be heard, it wasn't as significant as can be heard with the Fostex headphones.  Now, I'm curious where we'll end up once the plastix and foam get applied.  Hmm ...

Just looking forward to a good experience with these.  Also, I've noted that with my ears, the stock pads are actually not bad at all with the comfort.  If I could ask, how are people attaching the Shure 840 pads to the Fostex cups?

Thank you,

+1

Also adding tissue paper under the pads helps with the seal

You have to hold them at each point so they don't slip out again. It's quiet easy once you get the hang of it.  The Shure 840 pads make a significant improvement in bass I might add.

It just gives it a better seal than the stock pads.

By the way the Magnums and Fostex t50rp both have to be the best bang for the buck in hi end headphone audio.

Having said that, it's not because of the price that I like them so much.  I just love the sound signature of both.  Both have great mids for rock (guitar) and vocals.

I closed the earcup bass ports ~80% on my BMF V6.3 modded T50 RPs today.  Used the loop side of some peel and stick velcro to create the seal.   Just stuck it on top of the stock black fabric that covers the ports inside the cup. The bass tightened up in the lowest registers.  Made a noticeable improvement to me.

A agree that both are quite a bargain for the quality of sound obtained. It actually make it difficult to justify my other headphones  C'est la vie!
