Do you have any equipment that should be grounded (ie 3 prong plug) plugged into an ungrounded receptacle ? This could cause "grounds" to float and can cause popping.
I've had this with same experience with things as simple as source selector switches. My techie mentioned something about DC offset.
Clean wich switches? my Pro is only a few months old, should I just send it in for a look?
