I think that is pretty common for that particular model. I have a set of Audio Technica adjustable feet for my Marantz 6300, but it's because one was missing. Try a search here, I think you'll turn up some ideas.
Steve,
Where did you purchase the AT adjustable feet?

Sorry to hear that Paul. Well now you can hold out for a 630. You have to love a TT with a meter. :yes:

The difference is the color. X=black.I have a PL-518X in my second system. Would there be much difference between the 518 and the 518X?
