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?

It is rule of the National Electric Code that a cable system or satellite installation MUST be bonded (grounded) to the fuse box and ground rod of your house. If this is done you will not have hum or need ground lifters on the cable line. If your cable company resists call your local city building inspector and report the code violation. They will respond.

Thanks,
