The LCD-2 is my biggest disappointment probably. Muddy, congested and poor soundstaging. Not to mention they weigh a ton (but that´s to be expected).
edit: and easily the most overrated thing is all balanced headphones and headphone amps in general. Sure, they might be a small difference, but it´s nowhere near the trouble and the added cost.
I don't know what source you used, but when I was at a meet I heard the LCD 2 out of a Imod and a amp that I don't remember and it sounded like your description. But when I played it out of my rig (the one in my signature) they sounded spectacular.
Also balanced is a pretty big difference IMHO.
