I've got an "interesting" intermittent noise that predominates in the right, front speaker of my 5.1 system. Often, it isn't there but suddenly, without any reason, it'll begin or end. It's a high, buzzing noise like what you'd expect to be generated from a fluorescent fixture. If I insert some sort of power conditioner in the system will that filter out this extra-musical interference?

Some info that may be pertinent: If I leave the powered monitors on but turn off the 950 and Pioneer 45A, the noise is still present. It isn't the hardware, I believe. It's the power supply, IMO.

Anyone have a clue? If I do need a power conditioner, what should that piece have to solve the problem?
