Need Help with Popping Noise from Speaker


I'm hoping someone can help. My HD sateillite receiver is connected to my Home theater preamp. When I watch a HD channel and switch channels I get a pop noise emitted from the speakers. It seems to happen only when changing channels from a HD station to another station. Any ideas what could be causing this to happen?

poor design or bad/leaky coupling capacitor
whenever you get switching pops that's an indication of DC potential where it doesn't belong
