Done. Wow. The refined highs from the stock pads are back. Not as dull and dark as my second experience, which was a bit of cloth, yet no sibilance of unmodded oval pads. I don't have a lot of experience with quality gear and the best source I've ever had is a humble Cowon D2+ (rockboxed and patched for added voltage) so I wasn't sure I'd be able to hear the difference, but now it's obvious that the worst thing about sibilance (for me) is not even the harshness but a lack of timbre. The highs just didn't sound like real thing before your mod. So yeah, thanks a ton!

I can imagine the stock cable coming in handy during dj gigs. It's also incredibly strong, I seriously could not cut it with a normal scissors. Had to do it with some really sharp scissors instead.
 
 

Seriously, this headphone just doubled it's worth for me!
 
 

A bit of duck-tape to hold the cables in place while i insert the foam and driver!

It's probably the cheapest, and best mod available for this headphone! I actually think they're less sibilant now than with the stock pads.
Maybe it just seems less sibilant because the entire treble range is boosted, and not just 6khz region, which causes the sibilance.
And these headphones improve greatly when attached to a better source/amp. I use the fiio e7-e9 combo. Best thing is, you can get this combo under 200 dollars easily but it sounds really really good.
 
Glad I could help!
 
Now do the cable mod!

Looks great with the Mogami, did you got the 4 conductors cable?

I was thinking about getting Audioquest Dragonfly someday, but E7 (or E17) might a better next step, given their versatility and price. Not that you can get fiio that cheap in Moscow, but who knows. I mean, I did manage to somehow get my GMs cheaper than they are listed on german-maestro-shop.de
 
But if I do get Dragonfly, I may consider recabling the cans with something less intimidating than the stock things. No big *** plugs, that's for sure
As it is, I haven't done enjoying them and I'm pretty afraid to mess with them, given my zero experience with soldering etc.

Ohw man, you can get the fiio e7 for about 70 euros on ebay, but the gmps really do sound better coupled with the e9!
You could also get the dragonfly, and a big amp like the e9? Maybe even a tube amp like the little dot!
 
And I actually got the big plug because it's much much easier to solder, because there's just much more between the solder areas. And it just looks badass. 
If you have an old headphone somewhere, practice on those first.
But I have to say the cable is really easy to replace on the gmp, it's all very neat and the internal cables are pretty tough and thick.
Also if you want I could help you step by step, with photos.

I don't know. It's hard to think of Fiio now that I know Leckerton exists (damn you Head-Fi! ). There's no rush anyway: I've got other things to spend on and I've yet to enjoy listening to half of my collection on the current setup.
For the cable, still not sure if I'll get around to it any time soon, but if I do, might end with some Klotz things that already have 3.5 plug on one end.
Do you have to solder the other end, inside the cup?

Been away from the forum for a few weeks so I thought I'd share my impressions of the v900/7509 (non-HD) which I got used on ebay. Been listening to them almost daily since getting them, and they've given me almost everything I hoped for and more. They're a major upgrade over the v-6 for a portable, imo....besting them in almost all areas. I wanted a good portable without spending a lot of money, so for a bit over $60 used, I got way more than my money's worth. I was hoping for a closed version of the hd580, and I have to say, the v900 isn't a closed hd600/580. It's not as refined for sure, but I really didn't expect it to be, considering the price differential and the fact it's closed. However the detail retrieval is VERY good and the treble, while not very refined, is about the exact level that I like....a bit more than the hd580, but less than the 240DF, which was giving me sibilance problems. The mids sound very smooth and natural...with maybe a little dip in the upper mids, making them very non-fatiguing and flattering with vocals. The biggest flaw is a pretty big bump in the low end, but I wasn't looking for perfection in a portable phone, especially considering my budget. But most of my listening is focused on the mids and the detail and clarity is really impressive. They totally kill the v6, imo. I honestly could listen to them all day without fatigue and without feeling I'm missing a lot compared to my higher priced phones. Perhaps one day I'll get a good deal on a second hand GMP. I'm very interested in those after following this thread, but until that day, I'm more than happy with the v900 as a closed portable.

Never heard of leckerton, but I probably want it.

And yes, the other side of the cable needs to be soldered to the wires that are attached to the drivers.

I'm glad you like them, that proves that you don't need to spend monumental amounts of money to be satisfied.
Also a bass hump can be pleasant, especially in the train/bus or other noisy environments!

An audio engineer on one of the home recording forums raved about the 7509, and that's one of the reasons I decided to try the v900(same drivers). The dt250 is another good closed phone that can sometimes be found for an affordable price...unfortunately people who have them are usually reluctant to let them go. I had the 80ohm version and liked it a whole lot other than finding the highs a little laid back.

Maybe one day you should compare them to the 8.35.

I wonder if anyone has compared the 8.35 to the dt250/250ohms.
