Hmmm....maybe. I still think the bar can be higher and in fact should be higher. Let's see what good stuff comes out in the next couple of years. More planars and affordable electrostats is what I am hoping for. Along with radiator style driver headphones similar to HD800 at a cheaper price...also I realize that might be something like HD700, but perhaps from other brands or other models at cheaper prices.
Affordable stats does exist already. The 407+323s is better than most dynamic/planar combinations at the same price point. And don't forget the Koss 950/older lambdas
The only downsize is that Stax leaks sound way too much to be called headphone - and you could get some nearfield speaker instead
