The Nagaoka MP-500 is an excellent cartridge, but over your budget. I'd give a listen to the Clearaudio Concept MM. $250.
Cartridge suggestions
Hi. Helping a friend find a new cartridge for his Pro-ject TT. He has a 2Experience with 9" EVO carbon arm. Listens to mostly jazz/acoustic music. Phono stage is an EAR834P clone. Speakers are Spendor BC1's. Ideally a neutral and articulate cartridge as if anything too laid back might end up making the whole system a bit too mushy. As the phono stage only has MM capabilities, LO MC cartridge isn't an option. So, HO MC, or MM/MI options please. Looking to keep this under 500 and used isn't really an option. Thanks!
