I felt the LCDX hypetrain was very short in duration and that Hifiman perhaps doesnt get the recognition it deserves as a top tier can manufacturer..
I think Hifiman does, with the HE-6. About the LCD-X, it is more sensitive than the LCD-2s and LCD-3s, so factors such as those I've bolded below...
Sound: LCD-X
Previous Audeze models have been both loved (and hated) for their euphonically warm and thick sound, sacrificing treble and air for hard-hitting bass and mids you could seemingly drown in. The LCD-X , along with the LCD-XC, is said to be Audeze’s take on a neutral sound signature. The LCD-X has been highly praised on head-fi for being very neutral sounding, while having a bass that was less thick than previous models and treble presence that opens it up significantly. The LCD-X’s first and formost redeeming quality to my ears is its soundstage. The width of the LCD-X’s soundscape is about on par with other planars I’ve heard, but the depth has the potential to become awe-strikingly deep. There are at times where instruments two to three layers deep within recordings seemingly float out way in front of your head, although this is highly recording dependant on highly dependant on your mood as well. The LCD-X still retains the Audeze house sound and still imbues its own coloration on the sonics being produced. Texturally, everything is rounded off a tiny bit, decreasing the LCD-X’s perceived tactility and trading it for smoothness. However, what I can’t emphasize enough is that the LCD-X is definitely not a neutral sounding headphone. It might be Audeze’s take on a neutral headphone but in the grand scheme of things it is not neutral at all. The LCD-X takes the linear midrange of the LCD2 and to some degree the LCD-XC, and trades it for a noticeable and apparent recession in the upper midrange, while the bass sounds boosted and the treble, although not super prevalant, has a completely noticeable, small spike in the area around 9khz, which can sound a bit shrill at times. Overall I would describe the LCD-X as a u-shaped sound wih coloration not too dissimilar from the Hifiman HE-400, although its treble is way more in-ine than the HE-400, and its upper midrange a bit more prominent. This coloration, combined with the Audeze house sound which trades tangibility and textural richness for smoothness, lessens the LCD-X's realism for me, although it can still be a great listen for the right type of recordings. The bass extends deep, but with a little excess bloat instead of taught impactfulness, it gravitates more towards being atmospheric than visceral. The rough transition from upper midrange to treble grounds the LCD-X and weakens its sense of perceived airiness, which is a major trait that’s needed to sound realistic in my opinion. Instrument separation of the LCD-X is about what you’d expect out of any good planar magnetic-- in one word great, while the new Fazors help out in imaging a good amount, but the LCD-X can’t overcome its own coloration to truly get away from its marketing lingo as ‘reference class.' The issue of neutrality aside, the LCD-X is still a pretty good sounding headphone though, but isn't on the level of what it has ben hyped up to be.
.... are the reasons people have been getting excited about them. The soundstage of the HD-800s blew people away too, until they listened to the Cowboy Junkies.

Also, he said:
The LCD-X doesn't sound that bad when turned way up, but I'm not about losing my hearing.
How loud people listen is always a big factor, as much as what music they listen to. It'd be interesting to compare positive vs. negative impressions of the LCD-X against the SPL they were listening at, as well as the music. For other headphones too.
By the way, you'll all be interested to know that "appreciation" threads have been depreciated.
