.Thanks for your input as well. From what I've read is that the XTZ cartridge has been out of production for a while. Besides, if I would
spend $450+ on just the stylus, for the same money why wouldn't I just upgrade the entire cartridge??
You're right, for $450 you can find a good cartridge, but not the Joseph Grado Signature XTZ which is nowadays impossible to find and the cost would be at least $800+ But i saw the XTZ styli available - they are the best Grado ever made for that type of cartridges.
I have Joe Grado Signature XTZ and you can seach info on audiogon about this beauty, in the 80s the price was $750 and it was a flagship model, amazing cartridge, mainly because of the XTZ stylus.
So it's up to you, the cheapest styli for Grado is Black or DJ100i, so you can go lower if you want.
