The Ortofon 2M Bronze is definitely a good cartridge replacement from my 2 years old Rega Exact2 stylus. One problem i noticed was a regular hum during playback with it. I tried to ground the phono amp but to no avail. After reading up on how to eliminate turntable hum, one of the article mention to troubleshoot against the cartridge itself as it might be picking up magnetic interference. This lightbulb moment immediately prompt me to remove the Rega PSU underneath the plinth. Lo and behold, the hum is gone !
And the my friend is audio for the win.
