Why do the new 2009 Beatles CDs sound so good?


It seems a small (maybe big) miracle what they've done with the Beatles 9/9/09 cd box. These were always piercing and grainy (since 1987), and now they are just about the best CDs I have (and this includes SACDs). If it can be done here, it seems like this could be done with other popular music discs.
It seems that the problems in digital are not in the medium itself, but the way the recordings are made.
Companies like DCC and MFSL tried to improve things, but the Beatles box seems to surpass these by far.
A lot of people are quick to criticize digital vs. vinyl, but, to my ears, the Beatles now sound better than vinyl ever did. Anyway, if anyone could shed light on how this was accomplished, I'd be curious.

If you have a well recorded master tape and maintaining the sound quality throughout the manufacturing process is a high priority, cds with excellent sound quality can be produced. Some people will still feel that vinyl sounds better though.

Cd technology (and other digital formats) is steadily improving and will continue to improve for some time to come.
I just bought, on a lark, the Beatles "Rubber Soul" newly remastered CD... what was surprising to me, was the liner note stating this remastering was based on digital transfers made back in 1987 by George Martin (I think).
Well to me, this disc sounds really good. And I am wondering, why was this remastered from what would seem to me to be a very early digital transfer of imformation (1987)?? Why weren't these new remasters made from original analog tapes, digitally transferred now with the latest digital levels (you know, 24 bit 196 whatever)...
No matter, the sound is very good to me. I'm sure an original British Mono LP mint pressing would sound better but this is one good sounding CD.
I have to agree ... I bought Abbey Road and was so impressed that I went out and bought nearly all the remaining stereo remasters (should have bought the box set). Costco had them for $10 ea. I enjoyed them for a couple months and then after reading more reviews dumped a small fortune on the mono box set. I was very happy with that as well. Maybe there is still hope for some of the old classics? The Zeppelin remastered box set was very, very good as well.
