I bought a onkyo 502 reciever with the bose 5 cube speakers and a sub about 2 months ago. I have reciently heard static through my right speaker when i turn it on. Sometimes it goes away, and comes back. It is not the speaker because i switched the cables, so its gotta be something up with the receiver. I tried tightening the cables in the back, and i still hear static in my right speaker. I dont know if i should return it ( ift its not too late) or if there might be a simple explanation. AIght Thanks
