Back in the "day," when as a high schooler/ college student, I was exposed to the M75 while working at Radio Schack...our RS-series carts were supposed to be M75's. They sounded nice when compared to the other ceramics the cheapo equipment had, but I never realized how good something other than Shure sounded until I bought an ELAC/Miracord 620 from Tech HiFi...came with an ELAC 244-17 cart...OMG, the Shures were not even in the same league! Running a Sansui 3000 through Beovox 2600 speakers at the time and the difference was SOOO apparent...never looked back since.
I am sure, as I thought before my "awakening," that Shures are a good cart...but still run an ELAC 344 in my Rega and I cannot think of ever changing. Before doing handstands to find "that" stylus, consider there is a whole ocean of possibilities before you
