I've been listening to the Mono discs again in recent weeks, this time more critically.
Have the original 1987 discs in stereo but haven't played them in awhile. Don't have the 2009 stereo discs, yet.
So this is not a "Mono vs. Stereo" comparison on my part.
Though I can't quite put my finger on why, I'm finding these mono discs uninvolving, almost boring, to listen to.
Not noticing any mix differences and not expressing a preference for the stereo.
Didn't grow up with the group...those 1987 CDs were the first time I'd owned a Beatles album (other than a couple of comps.).
So it's not like the stereo versions were imprinted into my brain at a young age.
Based on what I've read I expected some sort of minor revelation but, for me, it's not there.
Still need to buy the 3 stereo only albums (Yellow Submarine, Abbey Road and Let It Be).
Am considering springing for the entire Stereo Box set instead.
