Audio Technica has kind of a silent recall for this cartridge. If you have bought yours around Christmas time like I did, and it hums, chances are it's from a bad batch. They are being sports about it, all you have to do is send it in and they will test it and replace it if it's a hummer.
All the work I did on my Technics to get it quite was a big waste of time for me, but at least now It's really nice and quite.
Here is the link to their website:

I am back in the pimping business!
