Since I was officially the first to know about the LE from Serge months ago, judging from what he has told me, a new filter and different wood selection will affect sound by a small amount compared to a good set from the very first batch. But the price is high up driven due to the fact you're buying a Limited Edition headphone with not so cheap custom wood selections.

The filter is different and I can get you pics from outside but not opening the headphones. My DIY skills are non existent
Yeh some pictures will do, no need to open them up as I don't want you voiding your warranty. I'm curious on the wood though, seeing wood gives me wood.
The Denon Dxxx, JVC DX1000's, TH900 etc all seemed to have a very different sound than plastics or metal cups. Maybe it's placebo or maybe it's me.
Indeed different wood do offer a slightly different sound tonality. This is due to the dampening characteristics and whether or not sound waves get absorbed more by the porous wood fibers or it reflects off it. Plastic and metal cups sound different to wood because they will almost always cause resonanting backwaves as sound goes through them, sometimes this can attribute to ringing or sibilance which is why some form of dampening is always good to prevent this.
Back to the Fischer FA011 Limited Edition, I sold the normal pair in anticipation of the LE and the buyer also remarked about a slightly recessed midrange.
Please Fischer don't disappoint me with the LE.
