I now own both LCD-3 and LCD-X and love both but the LCD-3's way it conveys emotion in the voice is what i love the most; the emotion just flows.... the texture of the voices, the timbre - love it.
LCD-X is a different beast - i prefer it on larger ensembles and when i want that extra bass kick; lcd-3 for when i want to feel
EEEK! that worries me if the LCD3 is going to sound more like an LCD-X.
I also love the LCD3 for that exact reason, its pure emotion!
If i wanted more detail or air or something I would not of got the LCD3
