Interference from subwoofer cable -- help please!

I have a home theater setup with an NAD T762 receiver and a Sunfire Super Junior subwoofer. Whenever the subwoofer is connected to the system, I hear very loud interference when I turn on the system. The noise is fuzzy, but it sounds like I am picking up an FM radio station. I have tried to switch out the subwoofer cable and also to use a different subwoofer input on the receiver -- to no avail. It's not the subwoofer, because the noise occurs even if the the subwoofer is unplugged. The moment I pull out the cable, the noise goes away. Another strange fact -- the noise tends to subside (but doesn't go away entirely) 5 or 10 minutes after the system has been turned on.

I would appreciate some advice -- this has been driving me crazy! Is there anything I can do to make this go away, other then doing without a subwoofer???
