Currently receiving a humming noise from my left surround speaker that is starting to get on my nerves, it has just started doing this in the past month. My System: Receiver Pioneer Elite 49tx, Cinenova Grande 5 channel Amp, Paradigm speakers all the way around, Studio 100's Front, Studio ADP's as surround, Center LCR450, Rear Backs Paradigm Espirits. Pioneer Elite Pr0 710 HDTV, Dishnetwork Satelite system w6000 receiver. Using 12 gauage Radio shack speaker cable for surrounds and Monster for fronts. Subwoofer is SVS 20-39 plus. I use the amp for the Fronts, Center, and Surround speakers with the rear backs driven by the receiver. Any ideas on how to get rid of the buzz would be appreciated.
