I might be beating on a dead horse by asking this question but I was wondering how these modded t50rp sound through a ipod Touch or  Sansa Fuze? Or do I need something like a hifi602 or 801 to make it sound good. What is the cheapest mod to do with the highest audio improvement?

Just curious (I already sent a PM to 1 person), what amp are you using it with? Was googling the likes of WA6 yesterday even though I know I WILL NOT AFFORD it

If you're looking for inexpensive, and DIY, try looking at the Objective2 amp. I personally haven't heard this combo (although the PCBs from the group buy seem to be making their way into the wild now), but early reports have been good. I know that LFF has used this combo for a while, so maybe he can chime in.

I've tried it briefly out of my iPod Classic. I do get sound out of it, but it will sound thin compared to a more powerful amp. Strangely enough, if we're talking pure volume, I can get the Fostex louder straight out of my iPod than either my Grados or Ultrasone HFI-580, both of which are notoriously easy-to-drive. But then when I plug into a proper source, the Fostex sings, while the others don't scale quite as well. 
 
Also, the mods with the highest improvement is mass-loading the baffle, and some sort of acoustic damping on the back of the cups, in my experience.

Which DIY amp will it be? I really like both of my amps with the T50RP I have but the V200 is better but also does add some warmth. The PPAv2 is perfect in terms of price to performance ratio since I got it at a steal but sadly the boards for the PPAv2 is no longer available.

per earlier, the facial sponge i picked up today and cut into the cups atop the paxmate didnt sound really any different than open cups with paxmate. like many others started doing a while ago like fishski and...cant remember the rest, the cotton balls in the cup work really nice. Thanks to LFF for encouraging me to try the cottonballs on top of the paxmate!

Waiting for my O2(amp) board actually

 
Someone's selling the Beta22 for ~USD930 locally
 
I'm intrigued by that V200.
 
WA6 looks elegant

 

[dogears]

Stock T40 + =

Easier than I thought

I'd like a comparison between your pawtex or whatever it is u call ur T50RP when you finish mods and get the chance to. What pads are those?

 

[dogears]

This is already way past half of what the Pawstex is doing
Pads is synthetic leather(?) from a local seller: http://www.cdrking.com/index.php?mod=products&type=view&sid=5206&main=34
worth <USD1 a pair. I stitched them together for one side (best sounding config for me).
Fuseboxx prefer 1 and wishing for 1.5 if possible [he owns DT770] when he listened with the Pawstex.
 
Hmn, maybe I'll stitch the stock pads together as well.
 
I'm off to cdrking later to get 2 pairs of the pads.
 
Ishca if you're reading this... want me to stock some pads for you???

 

[dogears]

Stockpads*2 on each side renders a different sound: thicker/flabby(?) bass that sounds like a ported (sub)woofer. Treble sounds polished and more extended.
 
And its definitely more comfortable

 

[fuseboxx]

Not sure if these cans really need a significant of modding since as far as I've heard, the stock sounds pretty good already and a matter of changing the pads - like what dogears mentioned - already helps with the bass quite a bit.

Having said that, the order I'd consider modding these cans is:

1) Change the pads
2) Play around with the 3x3 grills

I'd imagine one can do quite a bit of customization playing around with those grills.

^He means the back of the driver w/ the white paper thing removed and replaced with Transpore/Micropore/Masking tape combo as per my Pawstex (T50rp).
 
My plan is not to tamper with that anymore. Just to add my recipe on the cups and see how it goes

This is not really relate to this thread but i have just modded my current headphone while waiting for t50rp to be stock 

, inspire by dogear's ear pad mod:

The first thing i do was add some cotton wool to angle the pad, result was excellent, soundstage is wider, i can hear more detail. After that, i merged 2 pad together and expected it would be better. The soundstage after this mod is really wide but it lost the depth, the sound is more 2d. Maybe this mod is only work with the fostex?

 

[dogears]

^Heehee, thanks man. Not sure but it also depends on the pads.
 
 
BTW, fuseboxx prefers the stockpads*2 on the stock T40.

 

[dogears]

@proid, notice that my cdrkings pads are quite thin and its 'tougher' than the stock pads.
 
Just got from cdrking shop:

 
Stock T40RP2 with stockpads*2
(DT770 on the background)
 
fuseboxx w/ stockT40RP2+stockpads*2

 
note that pads are just pressing against t40 and fuseboxx

The T50RP requires some juice, a beefy amp, 3000mW into 50ohms aint exactly a light foot. The Schiit Lyr is a good powerfull tube amp, but I really want a Solid State, how would the Audio-GD C.2.2 go with the T50RP?
