I have the same cartridge and you can definetly tell when it will start going bad. They say a cartridge has about a 2 yr life span but that would depend on the tracking weight used. Not that I know anything about setting up a turntable. Benz has a great buyback program where they will give you a significant discount toward a new one. Retipping is also an option. I don't know what kind of music you listen to but I heard significant differences when acoustic music was played.
Good Luck.
