I'm liking these "masters." On that note, I find it delightfully interesting that
Rattle and Hum is referred to as a "Remaster" in the Digital Booklet.
Generally speaking, I'm not able to discern significant differences from original album cd releases and their subsequent Remaster releases. However, I believe I hear greater difference between any cd versions of U2 albums and their MFiT treatments.
In particular, I hear striking differences on
NLOTH and
ATYCLB. There are/may be others, too..., but I've not listened to all of them, yet. But with
No Line and
All That there is much greater dynamic detail. The bass is bass, the vocals are vocals, the guitars are guitars, and drums are drums... cleaner, clearer separation between elements. Hard to call these "differences" "improvements," right out of the gate, but I do like them.
NLOTH is much less "harsh" to me (in a good way).
