Hi . . I'm new here . . . thanks guys . . . I have a rega planar 3 turntable with a Grace cartridge that needs a new stylus. The current styus is a Garrott P-66. I'm told the stylus needs to be a moving magnet type. I have been to RadioParts . They sold me a compatible Soundring replacement Diamond Stylus (D 186 SR). The audio result is poor in comparison to the Garrott. Any advise or recommendations greatly appreciated.
