Headphoneus Supremus
I paid $2k for mine over a year ago from a dealer I know. Just been used for demo purposes in Vegas for a week. Well worth it at that price - best headphones I've ever owned. LCD3 are already very, very good, but I consider the LCD4 to be a slightly better LCD3 (about 10% better at everything).
Just beware - these headphones are quite hard to drive. I've listened on a Woo Audio WA22, which is no slouch, but for them to really shine you'll need a better/more powerful amp.
The LCD-3 is wonderful... as it can be had for $850-$1100 on the second hand market
The great thing about these companies racing to put out new stuff is that the older generation stuff can be had for great prices!
There are quite a lot of people on head-fi that sell after a year or two and buy the newer stuff.
