Here's a mystery for anyone to try and figure out.
Earlier this week I heard a crackle or popping noise coming from my speakers. It occurred a few times, randomly, as I was watching TV (which I use my system for). The crackling wasn't loud, and it continued even as I turned the amp's volume knob all the way down. The volume level on the amp didn't seem to affect the crackling volume. Later, I heard the noise when the TV was off and no source component was being used. (I keep the amp on at all times)
The integrated amp is a Rega Mira and is about a year old. The speakers and speaker cable are newish also.
It's never heard this before, what might cause these sounds? I haven't had much time yet to investigate, I'm kinda hoping the problem just disappears.
