You may want to use a turntable setup protractor to set the cartridge. What you have can be a symptom of improper cartridge alignment.
distortion at the end of record
it seems strange to me, but the songs at the end of the record seem to sound more distorted than those at the begining. i have a denon dp-45f and a grado gold cartridge. its set up per denon instuctions, but must admit its all kind of lined up by eye and small straight edge.its not drastic, but is noticeable to me.any suggestions would be helpfull. thanks
