Ground Loop

What is a ground loop? I understand that they can be caused by loose connections between components. What else can cause them? What are the effects? I have been told that humming from my power amplifier can be a symptom of a ground loop. True/False? Can ground loops cause damage to equpment?

Thanks for the input. Eldaford, how did you know I was studying to become a pilot?

Musicnoise: Please excuse the question but how do I connect the chasses together? Do I run the cable through the venting slots, tape the wire down to each component, use any method I can think of? When you say to run the wire to earth, what would be a good example of earth to connect to?

Update: I've decided to revamp my system. Replacing Denon AVR 2803 with a B&K AVR 507. May take Adcom GFA 7000 completely out of the equation. Hoping ground loop problem will resolve itself following changes.

Musicnoise: Thank you for your extensive explanation. Thanks again to all. I learned a lot from the process. Will be back on this thread if unable to resolve problem if it persists.
