Agreed. Try first to use other components. Also, if your wiring is a mess, try to separate wires that carry power, from those that primarily carry signals. GROUNDING is often a source of problems. It could be a pseudo charging/discharging from a failing component, like a small ampliflier. It could be the build up of capacitance (evicenced by volume variations) followed by a discharge of the built up capacitance. Hard to say. So swap out components as practical, move wires around, check for intermittant brokend cables and check groundings. Sometimes the plug in transformer used to power external speackers does not have a ground wire (avoiding loop currents). Moving those modules to a different circuit in your home/office might help. Good luck, Good Hunting! hth, James
