Thanks for all the reply's guys. Here are some answers to the questions.

Yes the cables are input to the 6/8 channel inputs on the receiver. Yes I have set the crossovers to 80hz for center VP150, 40hz for main M60's, and 60hz for surround M22's. The sub is low passed at 80hz.

The popping sound can be heard at all volume levels including very quite and only has ever come out of the center and the left surround.

The binding posts suck because putting bare wire (soldered ends) into these posts is something of a real challenge. The plastic cap has little to no space around it and you can't get a descent grip on it to tighten it down sufficiently.

I will post this monday as to wether the Onkyo is doing the same thing.. . but I doubt that it is because it wasn't the day before I changed the receivers out when I was listening to multiple SACD/DVD audios.

Will update more and again thank you much for all the input . .

I love the help and giving that occurs on this forum
