I had the same kinda impression too!!
I thought I was the only one!! hahaha.
I wasn't able to pinpoint where exactly but, comparing the LCD2 to the HD800s, the 800s just had a touch of extra class over the LCD2, almost making them sound heavy handed.
I wanted to believe the LCD2s were at the very top of the good chain. The wood accents look classy. The leather as well. For so long they've been my dream flagship. After side-by-side comparisons I was left feeling a little 'mehh' by the LCD2. And they're so HEAVY!........ the HD800s however....
