intermittent static thumping noise
Recently my Sony receiver has been making an intermittent static/thumping sound out of both Bose 201's. If I increase the volume the static does not increase. If I pull the receiver out of the cabinet and set it on the floor the static stops. Maybe bad rca cables? I have a Samsung smartv with a 3.5 audio out to rca on DirecTV receiver- rca from DirecTV to Sony receiver. Any input would be great. I'm gonna try to pick up new RCA's first. Mine are gold plated n Sony receiver is tin terminals so thought maybe that might be the issue. System has been hooked up a while and this problem just started. If I jiggle the cables there is no change.
