First of all all manufacturer get their cantilever/styli combos ready made by their supplier.I wish someone will show me something similar to this ZYX boron cantilever + micro ridge stylus combo.
It looks uniqie, not like any other stylus/cantilever combos i have ever seen. This is my own picture of Zyx Airy III cantilever/stylus on macro lens illustrate my thoughts very well. The nude diamong is going throught the cantilever from the top to bottom as you can see, there is no glue (at least i can’t see glue around the tip). If someone would like to find correct diamond to fit in the tiny laser hole made for ZYX Micro Ridge i would say "maybe the sound will be close to the original". But if the whole cantilever must be replaced, then i’m pretty sure it will be completely different cart and sound, because no other retipper can get access to this unique stylus/cantilever construction made expecially for Nakatsuka-San (ZYX) exclussively.
I don’t even want to speak about sealed body of all Zyx cartridges that retippers must have to destroy to open up, but the simple fact that ZYX unique cantilevers are not available to anybody else make my statement pretty clear. Nude diamond fixed in the laser hole in Boron cantilever, not glued to the cantilever. Refurbished ZYX is definitely no longer ZYX cartridge, but something different and most likely downscale compared to the original (because of the technology used).
