Yep, Audiofeil hit the most likely causes.
Needle/stylus damage or deposits on same is another possibility.
Could be anything though. Do you have another source (analog or digital) that does not have the same problem? That would eliminate the possibility of an issue with the amp or it's tubes or something with the speakers.
