Searched everywhere but couldn't find an answer that worked for my exact issue.
First, the gear:
Pro-Ject Debut III TT - Stock
Pro-Ject Phono Box II
Pioneer Elite - VSX-21TXH Receiver
Audioquest Sidewinder interconnects from the Pre-Amp to the receiver.
The Problem - Hum:
There is a hum in the system which seems to be caused by the RCA cables, mostly the right channel, to the pre-amp. When I touch it, the hum increases. I have found what seems to help, but not eliminate the hum, is to raise the pre-amp straight above the TT as far as the cables allow. It seems to be only vertically, not if I stretch it side to side, maybe because side to side makes the cables touch each other and the ground more.
I have the ground from the TT to the pre-amp, and have tried my Panamax power conditioner with no change. Both the TT and pre-amp are plugged into the same outlet. I've wrapped the cable in aluminum foil but hear little if any difference but I plan to try again with multiple layers on both cables. Also tried flipping the power blocks for both the TT and pre-amp in each socket up-side-down, no change. Also, I have tried best to keep the interconnects from crossing any of the power cables, have when moved close to them I noticed they do make the hum louder.
I think I've covered everything, any ideas? I'd love to just swap the RCA cables but they are hard-wired to the turntable.
