Thanks to all who have responded to my original post regarding a stylus upgrade from the original stylus of the Grado Gold cartridge. Certainly, most of you have much more experience with the Grado brand. Sure, better sound can be obtained with a complete cartridge/stylus upgrade. But, my original question was if the 8MZ would offer an improvement. If the Gold isn't capable of noticeable sound improvement with just a simple stylus upgrade then I will just wait until a later date and upgrade everything.There were styli mentioned besides the 8MZ. If those other styli are superior that is of interest. My phono stage is a Graham Slee Reflex with it's PSIU. It is only capable of support for MM cartridges. I know Slee has an extra piece (Elevator) that will provide increased settings for a MC cartridge but I'm not yet ready to make the change.As far as the Grado Gold cartridge goes....will all of the styli mentioned in this post fit into the Gold cartridge body?Thanks to all.
