The HD800 is not a complete winner, but each excels in different genres.
On a side note, while I had initially preferred the LCD-X to HD800 for being more versatile, I'm coming back to HD800 every now and then because I began to feel that the LCD-X's mids sound somewhat laid-back. I don't know if it's just me, but I find the LCD-X's sound signature somewhat V-shaped, like my previously owned TH900. For me, the midrange is very important, and I prefer it to be forward-sounding than recessed. This is one area where the LCD-3 beats the LCD-X in my opinion... the LCD-X is not necessarily a more neutral sounding headphone than LCD-3 like many people say, but just a tad less warmer sounding one with stronger treble energy. The more neutral sounding HD800 seems to have better mids than LCD-X, too.
This is why I'm eager to try out the upcoming HE-560, and compare its midrange to that of LCD-X. I have an HE-560 pre-ordered.
It's not just you. I'm in full agreement that the LCD-X is a u-shaped headphone, compared to other headphones and even compared to other Audeze headphones. Its upper midrange is more recessed than the LCD-2, LCD-XC, HD650, HD600, HE-560.
Nevertheless I'm getting my particular LCD-X RMA'd to see if the replacement will be better sounding (if they do anything to it in the first place.)
