Thanks James. So you absolutely will not implement parametric EQ on X3, or do you want to see the result of a poll and decide? If you like, I will happily open a new poll/thread in Headfi and ask people to vote whether or not they want parametric EQ on X3.
I understand that parametric EQ may introduce some phase shift/distortion. The question is how much of such distortion is humanly audible and can we implement parametric EQ below HUMAN EAR's (not dScope's) detection threshold. I would not be surprised if dScope can detect such phase shift/distortion, but if human ears cannot hear it then I don't care for it.
Plus, some people may be more sensitive to treble peak than phase shift/distortion; for those, the benefit of having parametric EQ on would outweigh the issue of phase shift/distortion. For those who do not want parametric EQ, they can just turn it off without affecting anything (when parametric EQ is turned off, it should NOT cause distortion, correct?).
The current treble reducer on X3 cannot nullify a 5 db symmetrical peak between 7-9KHz without affecting other frequencies, while parametric EQ can do that. Many headphones have such treble peaks -- your (my) Beyer DT880 is one such example.
