Just recently, my speakers started exhibiting static sounds while playing. It doesn't matter what the source material (dvd, cd, directv, etc.), it'll come and go, and I only hear it on the front 3 channels. It seems to be when the heat is running in my apt., but not every time it comes on. Is it just static build-up due to the dry heat in the winter? If it helps to figure out the problem, my equipment is as follows: Marantz SR7300 receiver B&W 604's, 601's, and lcr600 Speaker wire is plenum grade, bi-wired with Linn banana plugs All interconnects are AR Pro Series (including sub cables) SVS pci 20-39 Aura Bass Shaker Pros with Partsexpress 150W plate amp Hughes Directivo Lite-On LVD 2001 Any help is appreciated. Thanks.
