Subwoofer buzz

I have an hsu vtf 2 that has recently began to have a low level buzz when powered on. It seems to auto on with signal but buzzes. I tried disconnecting the sourse cable and the buzz stopped. When I touched the source rca pin going to the sub, the buzz returned. Any ideas on what this could be?? This new finding started suddenly, it worked well before.

Thanks

I haven't added any new components or changed ac system. The only thing I can think of is I recently to changed the crossover frequency on my meridian pre/pro. I have the sub set to crossover out so the pro controls, when I change the crossover control to the sub the buzz disappears???

Thanks for the help,

I tried disconnecting all inputs without benefit. When I plugged the sub cable into an old sub I lost the buzz. However, I am now using the sub crossover without buzzing. So, is the problem in the crossover of my processor OR is it in my sub??
