Several years ago I was walking around my house, when all of a sudden two people seemed to have a conversation in my music room. I grabbed a hideout, and went in. Nobody there, then they started talking again. It was coming from a Mission 707S speaker I had sitting on my main speakers. Just as clear as a real person speaking to me face to face. Listening to the conversation, I discovered it was the local police transmitting back and forth from base to cruiser. I looked outside, and there was a marked car sitting in the parking lot of a Pizza Hut across the street. The speaker wasn't hooked up to anything, except for the wire hanging down. I guess it was acting as an antenna. Freaked me out!
Never heard an amp do this before, ideas?
I have a primaluna 100 unplugged from any inputs. It has this awful high pitched sound coming from the speakers when it's turned on. It happens on both channels, and through headphones.
I have turned off all electricity in the apartment, turned all breakers off except the one it's on, moved the amp around the apartment, tried a humx, and different power cables. I even replaced the unit with another primaluna and they both do it.
I'm running out of ideas, anyone ever seen this before?

@hobbes101 Wish I had an easy answer for you. I understand the anguish. The reason I asked about electronic equipment in proximity to the amp is because of a similar annoying issue I experienced that turned out to be caused by a DirecTV satellite receiver. I guess those things are really poorly insulated. Even though it was a few feet away from my amp on the equipment rack, it was causing an annoying low level, barely audible hum I could hear through my speakers whenever the volume on the amp was turned up relatively high (music or no music playing). As soon as I got rid of DirecTV, problem solved! My WIFI is on my stereo rack's top shelf, about 3 feet away from my amp on the bottom shelf. No problem! My 55" LG LED TV is right above my rack. No problem! I've heard of light dimmer switches causing interference. I doubt the rest of the things you mentioned could be a culprit unless the wiring in your apartment building is really ancient. Best advice I can think of is to higher an electrician (a really good/smart one) to come have a look. Good luck! Just out of curiosity, I'd be interested in knowing what this turns out to be. Even with so called expert advice from a number of accomplished audiophiles, I had a devil of a time finally figuring out my DirecTV satellite receiver problem. |
@ieales thanks for the suggestions, I purchased some plugs and I'll try that!
I have svs speaker cables, but it happened with headphones and no cables too. |
