^ sounds like fazor has not been added to the LCD3 (or 2 for that matter), but tweaks may have happened that make the 3 slightly airier, either by accident (materials variations) or by design. Perhaps some members of Audeze customer support are less informed than others?
However it seems they are looking at adding fazor to a forthcoming LCD3 - seems plausible! - which, should it succeed, might well be called the sometime rumored 'LCD4' or some other model name...
If it's noticeably better and/or different and they call it LCD-4, I'll be totally fine with that.
I would love for either Sankar or Alex to explicitly confirm if any changes have been happening and verify the posts from earlier by their customer service.
