I've been living with both LCD-X and LCD-XC for weeks now...
The LCD-X is my favorite Audeze headphone thus far.
and the XC is FAR better than I thought during the show (more to come on that SOON):
I LOVE my LCD-3 (as stated in my
review for PFO) but the LCD-X sounds like the evolution of the 3 to me.
Like you said: I also find it more engaging with big classical passages, old school jazz, and even with well-recorded electronic music!
The soundstaging is far wider and deeper IMO. I used to grab for my HD800's too when it came to classical and such...
The LCD-X has the incredible warmth and looking-glass qualities of the LCD-3, but the air, the dimensionality, is unreal.
Plus the lighter weight also makes a difference! Though admittedly the weight of the LCD-3 never bothered me. Guess I was just transfixed
and didn't pay attention to it before!
Midrange clarity is spectacular.
The high frequencies are effortless, not a HINT of sharpness/edginess.
More listening and impressions (plus full review) to come!!
