Dear @nandric : So, that does not comes with Shibata stylus shape?, if you remember I found out in Netherlands an original JVC ( not Victor. ) NOS MK2 stylus replacement that you made it the favor to buy for me.
As I said the cartridge is good performer and competitive and my post about the Goldring was mainly because seems to me that the OP is interested in the stylus shape instead the cartridge motor.
It's obvious that it's almost imposible to find out a NOS stylus replacement for that cartridge but according my experiences with vintage MC/MM/MI cartridges several times the retipping makes a true quality improvement in the cartridges with a good cartridge motors as the X1-MK2.
