Bazaar buzz


So if I plug my ARC Classic 60 into the wall with the speakers hooked up and turn it on I get no buzz. Please note that no other equipment is plugged in NOR are and interconnects attaches to the amp or any other piece of equipment. 
HOWEVER, if the only thing I do is plug interconnects into the amp - nothing else, I get a buzz/hum.  Mind you the cables are ONLY PLUGGED INO THE AMP.

If you have interconnects hooked only into the amp, and not into your (or any), preamp, your amp will hum, as it is picking up RFI. You need to plug the interconnects into the amp and preamp to avoid this. 
Turn OFF amp and wait a few minutes before attaching to preamp!
(This is perfectly normal with an un-terminated input).Don’t connect to CD player!I’d turn off whatever preamp you're connecting, as well.

Your getting an "open circuit input buzz", if you put shorting plugs into the input, the buzz should go away, same if you have preamps cd players or dacs connected. (The input needs to see a load)

Even with interconnects from amp plugged into the pre, on or off, plugged into wall outlet or not, I still get a buzz/hum, though it appears to change the sound of the buzz/hum, but not the volume of it. 
I tried different interconnects and some are worse than others. The unshielded one being the worst offenders. 
Tried unplugging all kinds of stuff in the house to see if that would help to no avail.
