Although many reviewers have lamented that Capitol/EMI should have long ago released Volume 3 in their Capitol Albums series (and they're right), I've been fortunate enough to have all of the Capitol versions on bootleg CDs for a number of years. So, I already have CD-quality versions of the records I grew up with in the US.
That said, it came as no surprise to me that Universal, in their first Beatles venture, did not opt to use the original Capitol tapes for their U.S. Albums collection. Aside from the fact that I read about what the set DOES include within 48 hours of its release announcement, I also have been well aware that The Beatles themselves never really cared for (to be kind) the U.S. versions from the very beginning. The remastering team for this set did the right thing across the board - they combined (1) the U.K. first generation remastered material (with occasional added effects) and (2) remastered, unique, U.S.-only mixes to create the cleanest sounding revision of the original U.S. albums possible. I, for one, welcome this approach. I still have multiple copies and versions of all of my original US and UK Beatles LPs, 45s, EPs, cassettes, 8-tracks, reel-to-reels and CDs, so I can always go back and listen to those whenever I'd like.
I suspect that the average consumer, if they opt not to purchase the 2009 remastered UK versions of these recordings for some reason, will thoroughly enjoy this collection. One could argue that the bigger the Beatles fan, the more likely that they will already and/or still have the original Capitol versions in some format anyway.
This set was promoted to be what it is... a revised version of the original U.S. albums.
