Haha my HD800 is far from airy through my chain. Through the Vali, it is quite airy and crisp, but for my Bottlehead chain, I chose to sacrifice airiness for a more tactile and visceral bottom end. I've come to believe that you can only have one of the other (airiness and crispness vs. tactility and bass impact). When you reach a certain level of bass impact, it drowns out the treble and airiness. If you try to balance the two and still keep airiness, you won't have enough bass for it to have that sense of tactility. Also trying to balance the two can result in an incoherent mess. Like when I tried Quickie + Vali, it lost all the airiness treble qualities, but the treble still pierced my ears, and there wasn't enough bass for it to be fun or in any way impactful. Maybe there's a solution out there to get both airiness and tactility, but I have had no such luck so far. So I chose the one I prefer: bass impact and tactility. It's quite interesting how different the HD800 sounds depending on your chain. Through the Vali, it sounds close to an electrostat, whereas through my Bottlehead gear, it sounds planar-like (has a lot of body), but faster and more open.
