Agree on the recording quality of ALL the albums.
I remember listening to Joshua Tree on vinyl years ago and loving it. I just put together a good quality 2 channel digital system and haven't listened to much U2 at all, it just wasn't doing it for me. Then I got the remastered Joshua Tree. Wow - this is what I remember. Adam shines on many tracks including "In God's Country" and "Exit". The Edge's brilliance is heard with clarity on every pick. This release lets you hear the emotion in all the tracks that was lost on the first CD release.
