No offense, but I find it ridiculous when people proclaim this or that headphone to be worth a highly specific price and not a cent more. Ignoring for a moment that comfort, durability, and aesthetics are also part of the equation and not just raw sound quality---and also ignoring for a moment that personal enjoyment is pretty much impossible to quantify universally---assigning monetary values to sound strikes me as a pretty difficult undertaking.
I realize it's possible to speak in comparative terms with regard to value, proclaiming this or that headphone to excel or fall short compared to others in its respective price bracket. However these are still personal considerations, as comfort and taste in sound signatures and the whole shebang differs from person to person. We can speak of relative approximates of neutrality, judging headphones that come closer to neutrality than others to be "better," but once we get into colorations we've arrived in purely subjective territory. I mean, most headphones are substantially marked up in cost, and it's pretty much a given and thus something of a baseline as it is. Furthermore there are considerations beyond raw material like R&D, the engineering that goes into properly (or improperly depending on who you ask...) tuning the sound of said headphones.
If you look at the PS1000 for instance, just based on raw materials it seems pretty absurd given that it uses the same build elements found on Grado's cheapest models. However the sound of the PS1000 is quite unique amongst the current generation of flagships, and if it floats your proverbial boat then there's value there compared to something like the HD800 which, for all its engineering and fancy design, doesn't do it for some people.
I'm not suggesting that even in that circumstance the PS1000 is suddenly a screaming good value. I'm sure many satisfied PS1000 owners would have preferred to pay less. However there's a difference between declaring something to be steep and declaring something to be "worth it." One that goes beyond semantics I think.
