I've been given an old Revox B795 turntable. It has a Shure V15/IV - MR cartridge on it that needs a new stylus. Also with it is a new Ortofon VMS20EO MkII cartridge. I will be using the turntable to digitize LP's & 45's. Should I replace the Shure stylus or will the Ortofon cartridge match the Shure cartridge in performance?
