How does CD suck among digital formats (at least, from a sound quality perspective)?

For what it's worth, I am a member of a private music tracker and there are plenty of vinyl rips available. I've found that in many cases, the vinyl rips (which are digital files, by the way) sound better than the CD. This isn't because a) vinyl is better and b) CDs suck, it's because the CD masters in many cases compress the audio more and there's less dynamic range. Ironically, CDs have a lot more dynamic range than vinyl!
