There is a buzz and crackling in my setup and I am wondering what the source is. I tried to investigate ground loop or RF-interference by placing ferrite beafs on the power supply cable and audio input cables.
Below a picture of my setup. Black cable on the right is speaker cable.
What could be the problem causing the buzz and cracks in my setup? Sound fragment below:

When I unplug the ne5532 pre-amp, the buzz stops. The pre-amp shares the same earth. When i unplug the (white) audio cable from the pre-amp the buzz gets slightly weaker.

An externally hosted image should be here but it was not working when we last tested it.
