My thought is that there is tremendous market pressure toward making even high end headphones viable for portable use. Whether it means making small portable amps that can drive power-hungry headphones, or somehow making the higher end headphones less power hungry, the pressure is there.
I don't doubt that the absolute numbers are still there for desktop-only electrostatics and high end dynamics, but the numbers are going down as a percentage of the market, and the bean counters are very anal about that sort of thing. Not that they want to eliminate the niche product, or close the gap by reducing the quality and performance of the top end item. I think it's probably they're afraid of that huge gap between the $2k 'phones and that $8k or more 'phone and they want to fill in that gap some if they can, to lessen their risk if nothing else.
So exactly what Edifier will be able to accomplish I can't guess, but if they can make the high end electrostatic more relevant in the big picture, that will be a good thing. Relevant could mean a lot of things, but for me as an enthusiast who's willing to shell out even a few thousand dollars if the return is good enough, it boils down to "Can I ignore it and feel like I'm getting 99 percent of the best sound, or do I need to make the sacrifice and buy it because otherwise I'm a second-class headphone citizen?" (OK, so I may never be first class anyway, but you know, it's that nagging sensation that becomes more bothersome the more relevant those top end products become. So looking on the bright side, it'll be cheaper if they don't become relevant.)
