Improving ATH-W5000 seal, bass & isolation with bigger/thicker pads?

Having an average or slightly smaller head, I've never really had a great seal with my ATH-W5000. Being that I like the wearing comfort of these cans and would hate to part with them, I keep trying to fiddle with their position to try and get a better seal, along with a bit more bass and isolation. But no, positioning doesn't help a lot for me.

So, the next step is replacement pads.

So, has anybody tried any thicker and bigger pads for W5000?

I'm namely looking for pads that:

 - is cleraly thicker, when worn, giving a better seal

 - have a larger circumference, so that the pads become even more CIRCUMaural than the stock W5000 pads (which for me rest partly on pinnae)

 - fits w5000 with minimum of modding

Are there such beasts in existence?

Can anybody hazard an educated guess as to how the following pads would fit W5000 (i.e. big enough/too big, need a lot of modding, not thicker than original W5000 pads):

 - Stax SR-007 mkII (look slightly thicker in photos)

 - Sony MDR-XB1000 (big and plush)

 - JMoney pads (for Denon, perhaps can be custom made for other phones?)

 - Audeze LCD-2 leather pads (also meant for angled drivers and twisting cups, like on W5000)

Being on the European side of the big pond, ordering all of these just to try out becomes a very expensive trial.

So I'm trying to narrow down the options, before I embark on blind orders.

If anybody has experimented on any other thicker pads, please chime in.

Thanks, I'l put those on the list

I wonder if there are any other option available or experience from other W5000 users?

Would LCD-2 pads, which are very nice, fit W5000?

No more ideas from other W5000 owners?

Surely some must have tried bigger pads on their W5000 as the original pads aren't very circumaural at all.

Thanks, I quickly browsed the F5000 mod thread:

http://www.head-fi.org/t/214363/w5000-fitz-mod-guide

But the whole F5005 isn't very well documented to the extent at least that I can find.

Further, they do not solve the issue that the W5000 pads are just too small for my ears.

I need bigger pads.

Ah well, I guess I just need to order a second pair of LCD-2 pads. At least they are big enough.
