Also i want to add. Yes we all have our preferences but i find it kind of strange to give the frequency response of a headphone such an importance. If i wouldn't use the lcd x not also for music production i maybe would be happier with the classic or fazor and to me it would be the better headphone, the more fun headphone when listening to music. it isn't accurate but it is very enjoyable. i like bright headphones like the dt880 or hd800s as much as the lcd x. I like the thought that the companys create a music listening experience for their customers. Even you like it or not. But even if you eq i think you should like the stock tuning!? dosn't that belongs to the fun of the headphone game?
i also eq sometimes also for music listening. I can understand the worth of it. You can make the headphone a lot more capable.
accept the stock tuning, get along with it and see what it can give you vs. tuning every headphone the way i am used to it and how i like it.
I think it is a good idea to do both.
