Czarivey, good observation. Early CD were often recorded from not properly corrected tapes and digitized with jittery A/D clocks. This type of recorded jitter cannot be suppressed and the only way out is to digitize again, assuming that analog tapes still exist. They also went insane with number of microphones, since digital recording allowed for many more tracks. Microphone technics changed over time and everything matured but it took, as you noticed, many years. Today I have some recordings that are simply breathtaking showing no inherent flaw in the media.
Perhaps vinyl can be superior sounding, but I find it impractical. Investing and optimizing one system instead of two seems better to me since there is a lot of music not available on LP.
