Uh.. what? The R10 uses a very specific wood with a very specific shape to control resonance behavior. It doesn't have damping and the wood isn't "treated" in any specific way. It's using resonances to its advantage by altering the FR to add euphony and increase soundstage performance. The R10 is the only headphone of its kind; the level of engineering that was put into making it hasn't been seen ever since, making it impossible to compare it with any other headphone.
Using the LCD line as backup evidence is complete bull. Those headphones do not have earcups, the wood is completely decorative, it's literally a sleeve that goes around the driver, which incidentally is encased in metal. The driver just floats there, suspended off your head by the pads.
Even if everything you said is true, I highly doubt the FA-003Ti replacement cups are treated or dampened in any way; almost nobody uses damping in headphones anymore, they just slap drivers into the cups and call it good. Which is why 99% of all closed cans on the market can't even come close to matching open designs, especially regarding soundstage performance. In actuality if you made the best closed headphone you could make, said headphone would absolutely trounce an open design of the same caliber. It's just that no one ever does it because open is easier.
Sigh you need to learn a thing or two young grasshopper as you obviously don't know what you're talking about. Ok first of all the R10 does have dampening as does the CD3k both of which I've held in my hands and listened with me owning the latter. It uses white cotton wool as dampening, yes it's chamber design is of it's own kind but that doesn't mean any other company can't engineer it again one day. Every piece of wood is treated for whatever purpose it is going for, look up "wood treatment", no idiot company is going use fresh, raw butched lumber wood, pick a random piece, mill it down and use it for furniture, headphones or speaker enclosures, some do, most don't but it depends on what the end application is and where its going (indoor, outdoor).
Second of all saying using wooden cup's has high resonances is just plain bs, 90% of the time headphones using lighter material's as the back end cup such as plastic has more resonance than wood, don't believe me look up CSD plots for those headphones, metal grills in open design again resonant, these attributes are mostly not identifiable by FR charts, CSD plots and waterfalls reveal these issues.
With the LCD2's, you said wood in headphones you didn't specify where
so I made the assumption with my previous post that you were talking about wooden cups. Have you ever owned, listened or pulled apart any of the LCD2's? I don't think so, the wood is not just there for decorative purposes if Audeze wanted to do that they could've just made a wooden O-ring to sleeve around an inner metal ring or driver support which Hifiman did with there unreliable HE-5's that cracked like no tomorrow. Everything has an affect to each thing. You want decorative wood? The LE10's is your answer to that.
What I've stated is in general and is what should be done and has been done before, there is so much you can do with the design of a headphone and this applies to speakers as well, you can tune the enclosure/headphone housing/cup to suit whatever FR you're targetting for what the transducer's are most capable of in that design, there is so little you can do with tuning transducers especially dynamics, yes planars and ESL size of driver matters but at the end of the day you're not strapping bare drivers to your ears and calling it a final product, so using the right material, shape, distance of drivers, angled or flat, open, semi open and especially earpads these all affect the final sound and FR. Not all wooden cup headphones don't have dampening, I know for a fact that the Denon D2/5/7k range didn't which is why Mark made the mods posted here half a decade ago to dampen the drivers and wooden cups to get better sound using dynamat and dynaxorb, the FA-002/03 and Ti cups have something called steps which is milled out grove steps around the curvature of the inner cups, I've spoken to Dimitri before who works for FA and his sent me a diagram (subjective) one of differences in sound every cup they have offer's, this includes the 5 and 8 stepped cups, this is a form of dampening to elevate or attenuate the FR for a specific target or purpose, it's a common misconception to think dampening as adding wool to a surface.
Also comparing closed design to open design is apples and bananas comparison and I don't know why you brought that into the argument which the original statement you made was "wood resonate like crazy". As with the last point that you've said "almost nobody uses damping in headphones anymore, they just slap drivers into the cups and call it good" yeah this is true and that's why so many of those headphones are absolute crap when it comes to objective scale measurement. But you should know this by now.
