Grado Signature Model 8 worth re-tip?

Prices are quite a bit different.

8MZ is $175.00
XTZ is $475.00

Is their $300.00 difference in sound improvement, or just as important, is my Signature Model 8 worthy?

Just trying to put cost and end performance in perspective.

Really appreciate the posts and information!

Rich, for whatever it may be worth, I owned and used every all the mentioned Grados including the XTZ back in the day. I loved their full bodied, bold and lush sound. 
Is the 8MZ stylus worth it at $175? Without a doubt! Look at it this way: what else can you get of comparable sound for $175? I can’t think of anything. Also keep in mind its user friendly high output and good tracking ability. Is the XTZ stylus worth the extra $300? Probably, but I would put it this way:

The XTZ stylus is a substantial improvement over the 8MZ stylus. However, keep in mind that putting the XTZ stylus on an Sig 8 body does not make it an XTZ cartridge. As Chackter says, the XTZ is a great cartridge; substantially better than a Sig 8, but while the XTZ stylus works in the Sig 8 body, the XTZ has different electrical characteristics and much lower output than the Sig 8.

Good luck.

Thanks for your help!

Regarding stylus compatibility you can ask Grado direct.

Many of the LP Gear styli are NOT the originals, my advice is to stay away from their products if you don’t know exactly what you are buying.

Grago styli available from authorized Grado dealers, those are originals for sure.

LP Gear is an an authorized Grado dealer. I have bought replacements from them many times!
