The treble issue with the LCD-X is what I would consider minor and not on the scale of the stock HD800. We are talking about some edginess to horns, snares, upper end of female vocals, etc. Whereas with the HD800, the more marginal quality pop recordings, especially the remasters or stuff from the early 80s, are totally unlistenable to me.
My main issue with the LCD-X is that it isn't as cohesive of the LCD-2/3: Once I adjust to the presentation of say the LCD2.2 or a good LCD3, those headphones never fail to put a smile on my face regardless of recording, even the marginal ones. The LCD-X, with the its thinner, less tactile mids, splash of mid-treble, doesn't make me smile as consistently. Occasional, there's even a WTF.
Again, just nitpicking. I do find that the LCD-X is pretty good once I get accustomed to its sound. The LCD-X does have some very good technicalities such as speed, clarity, precision; but once I move back to the LCD-2/3 or even HE-500 (jerg/modular pads), I say to myself, "Ahhh, that's more right."
For those who are confused, expect the LCD-X to continue to generate more disparate opinions if the SD meet was any indication.
I have the LCD-2. Your posts really make me comfortable :D Thanks :D
