mjp: If you want to hear the most audible differences I've noted so far, check these out. I posted this on the Rick Resource website:

I suppose that now that I'm duly impressed by the mono set, I'm gonna have to get the stereo set. In the mono set, the greatest differences I've noted so far are:
1. Flange in Lennon's vocal on Lucy in the Sky...
2. Tempo and pitch of She's Leaving Home
3. Overall bass sound in the first four albums. In other words, it has beef! You could hear the bass before, but you couldn't really feel it. Please Please Me sounds like it was recorded last week with a bank of 15's on the bass. I Saw Her Standing There, in particular, really shines.
4. Lady Madonna really has opened up.
5. Hey Bulldog sounds fantastic on the Mono Masters CD #2. For some reason, the version on the 1999 re-master sounds over-driven and distorted. At least on my copy; no reason to suspect mine is any different. All of the other 1999 yellow sub tracks sound fine to me.
6. The Mono Masters version of Revolution is dirty and heavy as a box of lead. Lennon would dig this one for sure.
Some mild disappointments:
1. I really expected Paperback Writer and Rain (two of my all-time favorites, and just a brilliant period for me) to jump out of my speakers, but they didn't. A little extra wash on the vocals in the echo part of Paperback Writer, but nothing really new to me on Rain. They sound about the same to me. Maybe they were just done very well back in the day.
Well, that's it.
Edited to add: Damn; Rubber Soul sounds like a different album with Paul's bass just right up there. Listen to all of it. I've got a big old smile on my face for all of this.
