I have owned a 950 for about 2.5 months now. I have a loud popping noise coming from from SVS sub. The tech support suggested that I switch out amps to isolate the problem. This was done, no help. I changed the amp,interconnects, tried my old sub, which has an internal amp. None of this resolved the poping electronic noise coming from the sub pre-out. The noise is audible when I change the source, change channels on my PACE HD/Digital TV tuner, change the crossover points on the speakers, and when a DVD swithes from 5.1 to DD 2.0 at the end of the DVD. The pre-amp has exceptional sound quality. The cheap sounding noise when changing the above parameters can not be normal. If anyone has a clue as to what is the problem, please reply to this post. As of yet, no response fron Outlaw tech support, although they have been excellent throughout this problem. First contacted them two days after install. Tried all of their recommendations: Re-set pre, switched amps, switched interconnects, very annoying problem for such a high quality piece of electronic. What else? Thanks, Terry
