I don't know that this was there Saturday when I first hooked them up, but if I put my ear right up to the speaker, even with nothing plugged into them, and the volume on the speakers all the way down, I can hear a slight hum/buzz/hiss. They're plugged into a wall socket with nothing else. What're the possible reasons for this? Is this just something that some speakers exhibit, especially at this price point? How can I go about getting rid of it?
Thanks!
PS I absolutely love the speakers otherwise.
