If they can do something to end up with impactful detailed bass (after EQ if needs be) whilst retaining the other good properties of the HD800/HD800s, which I'd say are smoothness & completeness of treble above 8kHz and the soundstage/imaging then I think it would be a really good headphone. I mean I think they'd need to something about the general frequency response in the mids and low treble if relating it to the HD800/800s, in my eyes to make it more Harman, but that can be sorted with EQ, just you can't EQ good bass into the HD800/800s unfortunately and you can't really EQ smooth complete treble above 8kHz from measurements (not that the HD800/HD800s needs EQ'ing of that above 8kHz) so those last two points need to be built into the headphone design in my opinion. The fact they talk about reduced THD then this is a first encouraging sign that this headphone might be able to do good bass, but we'll see. If it does the things I mention then the price is high on a general level, but not crazy or outplaced in comparison to the other flagships on the market.
