I own a set of Audioengine a2 and a5 speakers, things have been very satisfying for me! However, since a week or so my set of a5 speakers started to make a strange noise while playing and even while not playing anything. It sounds like some crackling/popping sounds along with some sort of 'blowing in microphone' sort of sound. I already tried replacing the speaker cables and AC cable. And I used different power outlets along with changing the positions of the speakers. However nothing seems to fix the problem. Could it be a bad capacitor or something?
I can upload a video of the sound it produces, if that would further clarify my issue.
