This is actually getting very very funny.
Audeze's website referr to this graph:

Here's the thing, is that from pre-2016 revision of the LCD3 or is it from post 2016 revision ? Audeze has already confirmed that they have changed the sound in LCD3.
Ordering or purchasing LCD3 now, the consumer have NO way of knowing which version they are listening to, or purchasing.
If you go to a hifi store and listens to LCD3, eg. the new one, and you decide to purchase it, and the sales rep goes to his storage picks up whats just a few months old produced LCD3, but its the pre-2016 version. What you are listening to and what you get is 2 different things. Especially in this hobby where we take the product home and we spend hundreds if not thousands of hours digging into the sound with thousands of audio tracks.
Or, if the issue with the 2016 revision of LCD3 is that it HAS a spike in 10khz that has been mentioned here to be "uncomfortable" and you listen to a pre-2016 revision in store and the sales rep goes to his stock and picks up a 2016 revision version. Then you come home and you hear this "uncomfortable" 10khz spike. Again, its not the same audible product.
I do know different cans of same make also sound different, with different amplifiers. But the revision is hardware related changes to improve sonic sound.
If you ask me, this is getting redicolous by Audeze!
