popping noise when switching tv channels

I have a Time Warner cable box. Sometimes when I switch channels there is a loud popping noise but not all the time. The sound cable(coax) from the cable box (Scientic Atlanta 3200HD)feeds into my Mcintosh MX135 pre/pro. All my components are fed power from a Panamax 5500EX surge/AC regeneration unit.
Any thoughts on what can be done to eliminate this noise??

Thanks for the info. I will call Mcintosh in the am. I am using the MX135 Mcintosh pre/pro.

Switching the audio output of the cable box from coax to optical solved the problem. I called Mcintosh and they said it appears that the cable box was "throwing DC" when changing channels. I guess it was!
