Audio Technica AT ML-180 Cartridge Advice

I can't remember when I used any MM cart for the last time while trusting my memory at my age is asking for trouble. So I checked some of hose that I still own. AT 160 ML, AT 155 CL and Signet
TK 7 LCa. All of them have rectangular coupling and all can be
substituted for each other. 

@nandric ok, so if your cartridge is AT160ML then it is not a rare cartridge and not on the same level as the AT-ML160 (i thought you have this one). 

here is the AT160ML and it looks exactly like the AT earlier cheap models

And here is the AT-ML170 with ceramic body and a way different size of the stylus replacement assembly.

The transplant of the cantilever from one series to another series is another question, but those carts are different and specs are different, even the size of the diamond is different as pointed @ateal 

Dear @ateal: Good to hear that kind of quality performance. Btw, the 150 stylus is almost the same as the 180, that so minimum diference in between does not makes diference. Diferences can comes from the less resonant 180 stylus holder and that's why my advise was to try that kind of change where you can always return the 150 to its original stylus holder and this option must be inexpensive. The 180 boron cantilever vs beryllium in the 150 could makes a diference too but not night and day and maybe not better but only a little different kind of sound, maybe we can't even note it.

Very good " advise " from your part to use the 150 in the 180 body. Thank's for share it with us.

Regards and enjoy the MUSIC NOT DISTORTIONS,

Dear chakster. Lpgear stylus is not the same as AT 160 ML.               AT 160 ml has gold plated beryllium cantilever. In order to compare styli holders their inside-- is more interesting than their front side.        One can then see the kind of coupler  by each (round or rectangular)  and conclude which can be used ''as is'' or would need ''surgury''.       That is removal of the stylus from one cart and ''trasplatation'' to the other.

AT probably produced its own cantilevers/styli combo's in the  past     but at present all manufacturer get styli from their supplier. So             like the retippers they can ''chose'' what is available . The mentioned  ''short supply''' of the boron kinds illustrate this state of affairs. Ergo    chakster assumption about ''cantilevers made and adjusted for specific cartriges  by the producers''  can't be true.
