What does this tell me?

I've got a buzzing issue that I'm trying to track down, here's what I know.
(FYI, my amp is an integrated)

~It's only coming out of the tweeters of my Vandersteen 2ce's.
~It happens regardless of the source, DVD player, Squeezebox or DAC.
~It only happens if I select an input that has a source connected to it. ie, if I switch to an input that has nothing connected to it, there's no buzzing.
~I've tried every input and they all buzz when something is connected to that input and they all don't buzz if there's nothing connected to that input.
~I've tried different power cables and IC's, they don't change anything.

I don't know where to go from here. Is it the amp? Is this a ground issue? What do I try next?

Thanks,

Get some two prong adapters to see if it's a ground loop, try amp and/or sub first.

I unplugged the sub, still noise. I unplugged the Power Wedge with the tv, &
satellite receiver, still noise. I took a radio tuned to about 550kHz and walk
around with it, whenever I got near the side of the rack with the amp, Oppo and
Squeezebox, it went nuts. I then unplugged the Squeezebox, still noise. I then
unplugged the Oppo, still noise. All that leaves is the power cable going into the
amp, the interconnects going into the amp, the speaker cables coming out of it
and the amp itself.

I guess I'll try re-routing cables and see if that makes a difference. And I'll try
Samhar's idea of the two prong adapter.

Thanks for all the input, keep it coming.

With all of those things disconnected, does the noise still happen only when inputs are selected which have interconnects plugged into them (the interconnects being unconnected at the other end, if I understood your post correctly)?

The interconnects are not disconnected. The source that the interconnect is
connected to, is unplugged from power.

The only time there is noise, is when an input is selected that has something
connected to it, whether there's power to whatever it's connected to or not.
