I've always thought I could hear all the details just fine with mine. But I dont find them analytical. They can do loud, they can do soft, so they seem dynamic enough. The bass got a lot tighter and controlled when I upgraded my amp and source.
Havent updated yet myself. I'm about to switch to my Drobo as the library, but have been busy cleaning up the library a bit. Guess I'll not download the update if possible.
I just hope they dont nix that product entirely. I'd like for there to always be at least some form of player centered around audio instead of everything else. They announced the 120 right around the time the Toshiba 1.8" 240GB drive was announced.
