I have a Music Hall MMF-5, and have been using the AT-440MLA for about three years. There aren't too many hours on it - probably around 100, certainly no more than 150. Recently it seems every other album I play has a spot where the needle gets stuck. This wasn't happening before except in rare cases. Tracking force is at 1.6g. There are three anti-skate settings (four if you remove the weight completely) and it doesn't seem to make a difference either way. Thoughts?
