My problems with A/V receivers

[hrtbeat2]

I first started off with a Harmon/Kardon 6.1 with the speaker kit and the first day the sub was popping, so I returned it. Next I went with the ONKYO 702 7.1 channel THX receiver. My speakers were Infinity TS450 with a primus center channel. and a 8inch sub. The receiver is 100watts peak at 7 channels. Ok, The problem I was having now with my ONKYO was speaker popping? When at the start up music played it would pop and when it repeated again the same thing? So ONKYO said to reset the receiver, so I did. Didn't fixs the problem, so I took it back to CircuitCity and hooked it up to bigger speakers and the same thing untill I adjusted the crossover and turned the Hz (lower in) down and turned up the KHZ. But this did not solve my problem at home? And their receiver at the store did the same thing also, so I returned it and got another one. The new receiver did the same thing?? ONKYO said it was the digital chip or something like that. I told them it did not do it with my analog wires just Fiber opti cable wire? So I returned it and went with a 602 which was 7.1 x 85watts. The popping noise was still their? So I called Infinity and they said it wasn't the speaker, I called Samsung and they said it wasn't the DVD player HD841??? SOOO...back to the store and went back to the 702 my third one. This does the same darn thing just not as bad So I don't know what to do . Anyone had this problem??

start by unhooking your cable TV and see if the popping is still there.. that sometime causes a ground loop which might make the speakers pop.

Even if the cable isn't going anywhere by the receiver? If that solves the problem how would you fixs that? Thanks by the way

several places sell isolators. if that solves the problem, I'll find you a source. Keep in mind that you need to unhook all the cable lines in the house to check first, then add them back in one at a time until the problem reappears so you know which ones to isolate. then unhook the bad one and continue hooking all the rest one by one.

So I unhooked all the cables in my house, and what I noticed when unhooking them I was listening to my Digital cable and everytime I unhooked a cable the music would go out then come back on.? The results with every cable line unhooked was the popping noise wasn't as loud. When rehooking them all up you could hear one by one a increase in noise. So I'm thinking the cables in the house has something to do with it but their seems to be more? All my speaker wires are 18g THX with gold push in tips and none of the wires are wraped all around plugs.
