I own a Music Hall MMF 2.1 turntable and am looking to upgrade the cart to enhance the tracking and reduce the amount of surface noise/groovewear on the playbacks of some of my LPs. I guess the Music Hall is decent starter turntable. Is the cart on this turnable worth upgrading? If so, does anyone have suggestions? As you can probably tell, I don't know much about this stuff, so any suggestions would be appreciated! Thanks!
