The cables are defective and Nordost is going to rma them in this case. The shields probably got disconnected some how and that problem will not be evident by a resistance check since the shield is only connected on one end and there is a negative wire that connects the ground tabs on the WBT connectors. I don't know what happened to them or what the seller knew but Brf is right about Nordost. Thanks again for all the help.
I did not get the hum with any other cables so there is no problem with my equipment.
