Most of todays audio cds are horrible compressed, which usually is not the case with the LP releases. Nice example is this: http://www.youtube.com/watch?v=3Gmex_4hreQ&mode=related&search=
Though you cannot really hear the true quality difference in this clip, since youtube audio is of very low bitrate.
The way I understand it is that this is because compressed tunes sell rather better than uncompressed ones. It is not a problem of the medium; it is a problem of targetted marketing. Since LPs are manufactured in such small numbers nowadays, you can afford a gray beard who still knows how to make a recording which sounds good, and not just a recording
the suits think sounds good. But this is all a bit off topic.
