Audio Technica AT ML-180 Cartridge Advice

ateal, the reason is that I own AT 160 while I am not familiar
with AT 150. Because the cantilever/stylus combo can be removed
from its ''stylus holder'' and put in the other stylus holder there
is no fitting problem. All AT styli have the same construction. So
the relevant question for you is which is cheaper. 

@ateal where did you find the specs for the AT-ML160 model? Can you provide the link to the actual scan of the manual for this model? I’ve never seen any info about AT-ML160, but i have info about all others in this series.

I hope you’re not mixed up the AT-ML160 and AT160ML - these are two completely different cartridges and they are not compatible at all.

Chakster, i referenced the 160ML which Nandric mentioned and I also know it is not compatible with the ML150, 170 & 180 series. That's why I asked the question for Nandric. 

AT used two kinds of stylus holder coupling with the body in naive
hope to prevent styli. switching: round and rectangular. But they
''forget'' to change stylus construction. On the inside of each stylus
holder one can see a small hole with (painted) screw which function
is to center and fasten the whole cantilever/stylus construction. By
removing the paint and loosen the screw the whole stylus can be
''transplanted'' to the other stylus holder. So what is ''completely
different'' for chakster is not for other, more experienced members
(grin). But he probably can inform ateal  about the kind of mentioned
coupling. If those are the same by AT 150/160 and 170/180 than no
''surgery'' or transplant will be needed.

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.
