Now here is that personal preference thing, I love them for female vocals. I find that the Edition do a very good job of presenting what's on the recording. At least the female vocalists I listen to (and there is not a lof of bass on the recordings), are given a presence and authority with the Edition 9s. Just listened to Norah Jones and Mary Chapin Carpenter. I don't recall the bass ever overpowering the vocalist. Then again maybe I like a little more bass than Purk. (Or is Purk comparing them aginst his R-10s and of course they are going to come up short.
And I agree that they are great rock headphones.
What I'd say to the opening poster is that if you like the 2500, it seems a really safe bet that you'll like the Edition 9s. The Edition 9s do everything better and with more refinement. They are in the same family, but they seem very different due to the refinement.
I've been thinking a lot about the reference of where (equipment-wise, let alone personal preference-wise) someone is coming from. I recently posted my impressions on the AD2000. Probably before owning the SE & balanced Edition 9s and the SE and especially the balanced Senn 650 I would have been much more wowed by the AD2000. But in the back of my mind I kept hearing them against what was possible with my Edition 9s and the balanced 650s. So sometimes in reviews or impressions, it would be ideal to determine who has a set up and has the personal preferences similar to your own. Unfortunately, this is not very practical, but it is something I have tried to keep in mind as I've done my research on equipment. So here is an update (love the edit function)to my statement. Compared to the mid and high end of the in production headphones I've heard (and I'll include the balanced 650s here), the Edition 9s are great for female vocalists. And I would take them over any of those headphones for female vocals, except when I am in the mood to kick back a little with the 650s. And that's my personal preference.
