I have the ART-9 and it is a superb cartridge the best I have ever owned, however it has one of the smallest stylus on a cartridge that I have owned or seen, and being a special line contact type stylus I believe it sits deeper in the groove of the vinyl than most other styluses, The only problem I found with that is that I find it is not too forgiving on worn, dirty or lightly scratched vinyl, it really needs pristine vinyl to play on, and then it comes into its own, so unless your vinyl is of pristine condition I would not spend so much on a cartridge.
