Might've heard one of the veiled sounding LCD2s, they are out there and they sound really bad compared to the unveiled ones.
I prefer warmer headphones and think the HD800 is definitely thin and treble-tilted. So there's always that too. Different sound preferences will lead to polarizing and extreme opinions.
Mines are pretty new. Got them in June 2012 with the angled connectors. I like them don't get me wrong. A very fun headphone and sounds good on just about any amp unlike the HD800.
