CD sound quality
It's amazing how any discussion of CDs rapidly turn into CD vs Vinyl. The argumy ent usually goes "But there's been studies! It's scientific!" vs "But I prefer my vinyl." The thing is, the arguments tend to miss the point. For instance, vinyl bass response is often actually dreadful, but pleasing to the ear.
An awful lot of the perceived problems with the CD format actually are problems at source. For instance, early digital recorders had lousy clock jitter. This resulted in the well-known "CDs sound lifeless" problem. Furthermore, a lot of transfers onto CD were originally done from extremely poor third or fourth generation copies of the original tapes.
Overall, the situation is better these days, however the amazing habit of over-mastering has resulted in a whole new set of too-loud no-dynamics recordings. Try playing some RHCPs next to The Band and you'll see what I mean: The Band sound infinitely better, and it's not down to the quality of the music.
So are CDs technically better than Vinyl? Yes they are, but the industry has gone a long way to making them sound worse.
