Listened to my son's LCD2rev2's on my Lyr/Bifrost after I got the Uber upgrade. The most noticeable difference to me from what I remember from the LCD's before the upgrade was the increase in detail across the board...and as people have mentioned in this thread in other places, especially toward the higher end. This may or may not be a welcomed addition for you on the treble side because it can seem a hair brighter....but many who have LCD2's are looking for a bit more in that rolled-off treble region. Soundstage to me is a bit more 3 dimensional to my ears...bit more space between instruments. I would be very surprised if you weren't happy with the Uber unless there is an overconcern with not wanting your high end signature sound affected. Good luck.
