I know it is a matter of semantics, but it is probably not the cartridge that is humming, unless you got a defective one. There is more likely something wrong with the way you connected it. In other words, any system will hum if any cartridge is not correctly connected. Do you hear a very loud hum that seems to be low frequency, around 60 or 120Hz. If so, that suggests that one channel is not properly grounded in the audio circuit. Do you hear the hum in both channels or in one? Your post suggests that the amplitude of the hum is volume control dependent. Is that the case?
Help! New Nagaoka MP 500 Cart Makes Hum Ground Noise
I have the new Nagaoka Mp 500 cart installed on my Techniques 1200G turntable connected to my Luxman 595 amp. When I turn the volume up, I hear a hum in the speakers. If I remove the cart from the arm, the hum goes away so I know it's the cart. It's with the original Techniqs head shell. I didn't have the issue with the Oltofon 2m Black LVM cart.
Aside from that, I like the MP 500 a lot. Sounds good. But I am freaking out... not sure what to do about the hum grounding noise?!?
On my luxman, I have both the turntable and the REL sub on the ground in the photo.
