So far, all the pictrues I've seen of the ''e'' serie, have their drivers sticking out from the cuo, not much, but I'm sure it makes a difference, I know for a fact that the PS1000e, are louder than the old ones.
I have owned the PS500 for about two weeks, but I never got used to their bass extension and treble rolloff. I took them back, and gought the PS1000. Now if I had known then, what I know now, i would have tryed the G-cush on the 500, that way, the bass would have lightened up a bit and the treble would have gotten a dose of sparkle, and as a bonus, the bigger pads, would have expanded the soundstage, win, win, win, if you ask me!.
Let me know what you think, is this all to good to be true?, am I missing something here?
