That's where science ends. Our ears are not at all the same and response differently to frequency ranges. So unless, you could claim that your hearing is flat, the saying of hearing music as intended is getting really old. Well, at least, for me it is already for over 20 years. If we are all robots with calibrated hearing, it might make some sense but obviously, it's not the case here. This is why some of us enjoy the abyss while others prefer HD800 and even Beats HPs
. Let's stop throwing technicality at each other as the standard.
I do agree with you about the abyss not being better than HD800 though. I wouldn't pay more than $1500 for that HP. $4000? Forget it. I'll take stax 009 any day.
