I currently have a panamax power conditioner thinking it would also stop the thumping noise every time a flourecent light turned on and off, but it did not work. Once I upgraded to a shorter outlaw sub cable from a diomondback audioquest cable that was about 10 feet to long, and I also ugraded from a 1050 to a 970. I am pretty sure it is the new shorter cable that fixed the problem.
