With my limited knowledge and informations available over net, there are four varieties of MM cartriges namely Spherical, Elliptical, Naked elliptical and Shibata(Most expensive). Due to the shape and cutting of the diamond tip of Shibata stylus, its arguably the best among MM cartirdges since it is believed to access the maximum area of a vinyl groove. While Entry level Audio Technika Shibata(used) retails @200-400 usd, the Ortofone 2M Black retails @600-800usd. Nagaoka MP 500 @700 usd. Now my question is, In case of Listener of Indian music, Bollywood 80-90s, classical and modern basic albums, is it really worth? or with a morderate set up of TT, Amp, speakers (combined within 3-4 lacs) Does it make at all any sense to go for such pricy Shibata? How much qualitative difference one would get? Anybody having first hand experience may please shed some light..
