I think you kinda proved my point. I've had the LCD-X for 5 days now and they have never been bright or peaky as you described them. Had I gone off your meet impressions I might have missed out on a chance to hear a spectacular pair of headphones. Sorry Arnaud, you really need to hear them on my setup...their treble is definitely one of their strong points. At times, they feel like a progression over even my LCD-3s (while never venturing far from the Audeze sound signature). Never once have I found myself with troublesome treble energy as I have with so many other headphones (HE-6s, K702s, DT880s, SRH940s). In fact they are still very much Audeze headphones with treble that never leaves me wanting for more (or less). Seeing that we both hear the SR-009s similarly, could be again the meet conditions of unknown music, unknown gear, etc...or we just happen to disagree here?
Just to roll back to my "meet condition" impressions of the SR-007s...I was never impressed enough to buy them. But I've since heard them in the proper conditions and proper upstream rig (previous ones where all with Stax amps) and now I might end up picking up a pair down the road. I'm not saying your impressions were wrong, far from it, but just when it comes to meet conditions (especially for my personal meet impressions) I always take them with copious amounts of salt for the reasons mentioned above.
Exactly how I hear it. In fact, the LCD-X have very linear bass all the way down like my LCD-3s (with a bit more oomph than the LCD-3s).
I really think you'd enjoy these. Based on your previous comments of the LCD-3s, these seem to be more up your alley. As Tyll mentioned, it appears the measurements posted are a work in progress, but they do look quite good. The 300Hz waveform no longer has a double leading edge (hopefully that will show up in the final measurements too) that can affect imaging.
Peter, to me the LCD-X was not excessively bright nor peaky. I actually liked their balance, and their bass.
My problem with it was that it did not have the smoothest treble (possibly due to notches, not peaks), at least the one I've heard, which might explain some of the weirdness I heard. I could give them another shot. Also, I'm not the only one with that assessment either. Some people I trust have been auditioning them for longer than 5 days with similar impressions.
Not sure if there are product variations at this early stage.
As far as meet conditions, their reliability depends on many factors: familiarity with tracks used (including mastering), if a baseline was used, experience, and so forth. I definitively agree that they will never be a the level of a 2 week evaluation. However, they are far from worthless IMO, unless one was just doing casual listening.
