But it really is a weird kick in the pants. Just to be clear, I have the ground from my DIN cable grounded to the Plinius phono preamp. The Plinius has its own power supply which terminates in a three prong plug. The VPI PLC has a captive power cord that terminates in a three prong plug. They are both plugged into my Haley power conditioner. Up until this started happening everything was working like a Swiss watch.

I started troubleshooting. The first thing I did was remove the cart. Much as I hated to do that it seemed like a smart first step; it gave me a chance to carefully examine the wires inside the cart and take another, better look at the whole thing under the Dino-Lite. That all looked good. With the cart removed I turned on the system and was still getting hum (I made sure the cartridge clips were not touching). Long story short - I had to unground the DIN cable from the Plinius and run the DIN cable ground directly to the VPI PLC! I never in a million years ever did that before. For some reason now that's the only way to make the hum go away.

Okay experts - what in the world does this suddenly suggest?
