I have solved most of the problems I was having this afternoon. I did go to the hardware store and picked up some 16g copper wire to make some ground leads. I have now connected all of my components to the ground lug on my power supply. My phono stage is a rogue ares. It has selectable dip switches for the grounding. I switched it to ground only the right channel. This made the majority of the hum go away. I can only hear it now when the volume is maxed out. When I am listening at my normal volume at my chair, I cannot hear a hum. I can hear it when I stand next to the speaker.
I talked to Peter Lederman from soundsmith this afternoon. He was nice enough to help me troubleshoot a bit. He said I might be having an issue with my exposed tonearm wire on my JMW 10.5 tonearm. It does not use a shielded wire. This may cause some interference with my high output moving iron cartridge. He said to try wrapping it with a single strand of copper wire. A small wire like the size of a hair. Then terminate this wire to the ground lug on the turntable. This should help to shield the tonearm cable.
He also suggested using some 3-prong to 2-prong adapters and only earth ground one piece of your equipment. I am going to earth ground my phono stage and then connect my turntable ground to the ground lug on the phono stage.
I did try the turntable without using the ground on the phono cable and it sounded worse. I will try these ideas out and report back later.
