I didn't mean to demean Bob Katz or the other commenters for their views, but just cite them as extreme examples of how some diverge from the mainstream.
(Heck, I even agree with him on how nice the SR007 and I actually prefer it to the SR009.)
To sum up, from reading the early LCD4 comments, I was expecting a slightly better LCD3. I was wrong.
It's far better, and a departure from the LCD2/3s because of it's significantly superior tonality, definition, and spaciousness, sweet smooth vocals, and profound bass.
FWIW, if it helps to define my tastes, my favorite phones are the LCD4, SR007/Mk2(current version), Grado PS1000e, and the HE1000. I feel all of them are brilliant, but very different.
