Ortofon 2m blue/red/silver are all elliptical stylus, the channel separation is not exceptional, decent channel balance.
I recommend you choose an advanced stylus shape (shibata, microline, SAS, ...)

IMO, this is an excellent choice when moving up, microline, channel sep 28db; channel balance 1.0 db.
Aside from imaging, it sounds great, everyone I recommended it to is glad they bought it.
Begin by checking the channel separation (higher is better), and center balance (lower is better). Those two relate to imaging.
Then check what other’s say about that cartridge’s musical performance.

Next, look to upgrade your Turntable, and move that cartridge to it.
