Well lets see, clarity wise the HE 6 was cleaner sounding overall. Bass extension was deeper and also cleaner on the HE-6 but not by much. The LCD 2 had a more warmer sound and the bass was fuller sounding then the HE-6 and had a touch more resonance in it's mid bass. Transient response was very good on both of them but the HE-6 treble could come across as more harsh on some songs while the treble on the LCD-2 was smoother. That being said the HE-6 seemed to sound like it had more air in the highs. I would have to give the title of genre master to the LCD-2 because it seemed to sound acceptably nice with everything while the HE-6 not so much so. I didn't like it to much with some rock tracks although I will say Lenny Kravitz American Woman and Are You Gonna Go My Way sounded quite nice on it. As far as mids went I liked the LCD-2 even though they weren't as clean sounding compared to the HE-6. Guitars had a weightier sound and a more satisfying crunch behind them which really made me want to tap my feet. Marilyn Manson's Beautiful People sounded very very good on the LCD 2. The HE-6 came across as the more aggressive faster more revealing of bad source headphone while the LCD-2 came across as the more laid back mellower sounding more forgiving of source headphone. Honestly, both headphones were winners in my book. You can't go wrong with either of them they're both phenomenal sounding headphones. I'm hoping my buddy keeps his HE-6 around for awhile so when I get my Paradox I can do some A/B ing and see how it stacks up to a HifiMan top tier can.
