I had a similar problem with crackling and a hum through the speakers. I had recently added a Nordost Red Dawn (flat cable) IC and thought it was defective. I was just about to return it when I decided to unplug the wall whart to my Ikea turntable lamp. Problem solved. Check around and see what is plugged in that could cause noise and remove them one at a time. In my case, my Nordost cable is unshielded so it picked up the noise. Good luck!
