I have an older pair of RP-3 loudspeakers which were in climate controlled storage for a number of years. The sound reproduction is light years better than what I've been listening to for the past ten years. However, the issue is this. I get a loud electric static pop thru the speakers when motorized things like ceiling fans are turned off. The speakers are shielded with a surge protector, which is turned off when the stereo is not in use to prevent a potential electrical surge. We've tried connecting to a different electrical outlet, but get the same results. I was told that it could be a ground in the apartment wiring that needs to be replaced, but "likely it's a characteristic of the speakers". I've not had this issue previously so I'm not willing to blame my Klipsch yet. Has anyone else ever had an issue like this? Does this sound like an amp issue to any of my fellow audiophiles?
