Syl, how loud is the sound, and how close are you when you notice it? Most speakers will have a very soft buzzing (or power) sound when the receiver is turned on, however, you usually have to be pretty close (1ft or less) to hear it, it would not be audible from the seated position.

A ground loop buzz is pretty audible. If you think of how a tranformer on a power pole sounds, buzzzzzzz/hummmmmmmmm, if your close to one, that is what is sounds like.
