Aside from other factors, I want wide separation and tight center balance to provide more distinct imaging.
2m black has good +/- 1 db center balance, however it’s channel separation is very low at +/- 15db.
I also recommend getting a Shure V15Vxmr body (original stylus likely broken), and getting a replacement stylus from Jico. My choice was Shibata on Boron cantilever.
Here’s a V15Vmr body with I don’t know what stylus in it for $285.
Teh get the Jico Stylus for another $285.
Total $570. plus shipping, for awesome result
The Jico has a brush like Shure’s, you can use the cartridge with the brush up, not on the lp, or, lower the brush when desired. Note, Shure’s brushes were/are damped, like shock absorbers, best for warped lps, the Jico brush is not damped.
