I replaced a recently broken in M97xe stylus, which I heard is a big deal with the 97xe, with the Jico S.A.S. today. The first albums I played were Fleetwood mac and Steely Dan's greatest hits, I was in love with it! It blew the stock Shure needle away. Then I played some albums that a bit worn and some poorly produced albums and I was a little bummed. With good albums the sas is GREAT, with poorly produced or worn albums it seems to be little or no improvement. As with all audio equipment the better it is the cleaner it is, if you put shit in you get shit out. You can't polish a turd. Overall I play albums that are in good shape and well produced, so I would buy the SAS again in a second.
Hope this helped.
