I'M about to pull the trigger on a new Parasound 2205 Amp. I am currently testing it with a Pioneer Elite VSX 36 receiver. I have lifted the ground on the amp to eliminate the hum but am getting allot of popping in the speakers. All I am trying to do is buy a little time before purchasing a pre amp. Questions. Is the amp to powerful for the receiver? For this price range should I be looking for another amp? I do not want to be purchasing another amp for many years. This maybe my one opportunity for me to step up into separates and I do not want to make a mistake. Considering a 950 Outlaw or an older Parasound?
