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.

Sorry misread your first post, as you have a buzz when the inputs are open circuit, but in fact it’s the only time the buzz is not there.
See if you have a buzz when you plug in some "shorting rca plugs" into the amp.

Just to add, if you have a Buzz still with the inputs both shorted, then the amp has a problem, and needs to be looked at.

I noticed today if I unplug on IC lead while amp is on the buzz goes away. This is while the other IC  is still connected

You shouldn't ever unplug anything while the amp is on, this lead to blow ups.
Do what I said with shorting rca plugs. If it's their while both inputs are shorted, it needs a tech to look at it.
