Is my power chord going bad?

Hello all, 

I have a power cord purchased from an independent cable maker. When I touch the interconnects running from my phono pre to my preamp to the power chord I get an audible hum coming from the speakers. This doesn't happen when I touch the interconnects to any other power chord in my system. The cord runs directly from the wall socket to my amplifier. 

Shouldn't a properly shielded cable not allow this to happen? 

Thanks for any advice!

Right on. They don't touch regularly it was just something that happened that I noticed. I definitely know cables shouldn't touch.

So the question becomes, are all your interconnects the same make and model, or is the one running from the one on your phono pre different?
