If it sounds fabulous why change.
In my view, with vintage cartridges, the most difficult challenge is finding one with a stylus and cantilever in excellent condition ( if not new ). You can always buy another body sans stylus.
ATN160ml Beryllium MicroLine Stylus on AT150e body
link to the eBay item I bought
I wanted light 1.25g tracking, and stiff Beryllium Cantilever (best bass I ever had was Shure V15Vxmr beryllium microline, SME arm, TD124 TT, tracking was 1.0g),
I got both, and the azimuth adjustable headshell.
It is a Genuine ATN160ML Beryllium Cantilever with MicroLine Stylus
............. HOWEVER ............ I removed it from the headshell, it’s ID is on the top
The gold body is an AT150e, not a at160 body.
(they look identical, let’s say seller probably unaware)
Aligned, played 1 side of an LP I inherited, it sounds fabulous
I’ve been listening, getting ready, my AT33PTG/II boron; Sumiko Talisman Sapphire Tube both track at what I consider a heavy 2.0g
I recently found this, Julius Pepper Adams Baritone Sax player gives his Bass Player George Mraz many solos (as well as the pianist and drummer). Thin flimsy vinyl, holy smokes it’s well recorded, live in a small club.

seller has many cartridges, a few like this, so would you return it, try to get one with a true AT160 Body?
Anybody know what difference it might make?
