Hum in preamp when using HT bypass

I have a Sim Audio P5 preamp that has an HT bypass input. AT first I was using RCA interconnects from CD to preamp, preamp to amp and the HT bypass and had no problems. When I switched to balanced from CD to preamp and preamp to amp leaving the RCA connection for the HT bypass I am getting the hum. There is no balanced input for the HT bypass. When I choose my CD input I do not get the hum, only when I switch to the HT bypass input. Any suggestions?

Is on a different AC leg at the AC Box
To test if this is the case just plug in the whole system into One outlet strip out of just one dedicated outlet
and the hum should be gone.
Next have an electrician place the dedicated line on the same leg.
Let me know if this fixes
