I got my Metas a couple of days ago and will post more lengthy impressions after I have some time on them. At first, they sounded a little closed in and the lower midrange/upper bass was somewhat muffled (not uncommon with new speakers before break in). Last night they started to sound more open, with a nice depth to the soundstage (but not much width). The top end is very clear without any harshness, even on first listen. I had the original LS50s a couple of years ago, and just going by memory the Meta is a definite improvement.
