I got mine yesterday and I'm loving them.
I had the original LS50s paired with a couple of small REL subs and found it quite nice, but decided to splurge and buy myself a pair of Metas for Christmas and made the switch to the Metas yesterday afternoon.
"Composed" is a good word, they just seem to do things right. Beyond that I'd say words like holographic, musical, and smooth would apply. It's much more of a "right here in the room" type of experience than the original LS50s. And this is right out of the box, not sure if they will improve with break in, but I'm completely satisfied as is.
Listened to the remastered Tom Petty Wildflowers that someone suggested further up in the thread and it was great. Currently marveling at the way Norah Jones voice is filling up the room.
Two thumbs up.
