According to Billboard, "The mono records, which will be available as
individual titles and in a 14-LP/108-page book box set beginning Sept. 9,
were pressed from the original master tapes, all of which are in superb
condition after the "Please Please Me" album. New pressings were A/B'ed
with original British pressings." So it appears they were not digitally
"enhanced?" in any way. They are the original mono master tapes. That's
what makes the release different.
