A mystery for you tech gurus out there

Hi all -

I am stumped, to say the least, at what could be going on with my home theatre system. My equipment hooked up is:

-Denon 1913-AVR receiver
-Dual CS7000 (Golden one) turntable (grounded to a casing screw on the receiver case)
-Marantz 5 disc CD changer
-Front speakers: Paradigm studio 60 v1
-Center and surrounds: Sony
-Klipsch subwoofer
-Panasonic plasma TV

So the issue revolves around the front Paradigm Studio 60s. Whichever one is plugged into the FRONT LEFT speaker output on the receiver emits an occasional, loud pop. Usually the pop comes in bursts, and sounds almost like a fireworks show would with a succession of airy-sounding, concussive pops.

I thought it was my receiver (I originally had a Denon 1911-AVR giving me the same issue) and recently got the 1913, and the issue persisted. I have tried using new speaker wire as well. The part that I cant figure out is when i go behind the receiver and switch the 2 front speakers around so that the speaker that was right is now left and vice versa, the popping now comes out of the right sided speaker which is now plugged into the FRONT LEFT output.

How can this be? Any thoughts or ideas?

Liz I simply directed to purchase with return to try. It's not a crime cuz you can return item to Best Buy for reason or no reason within the month of purchase. Hey even if you accidentally fried one or two of them with bad amp, No problem as long as it's done within a month your funds are secured and refundable.

Marakanetz, that was one heck of funny response! Elizabeth, that would normally be good advice, but, if it's actually doing it with all those different inputs, it doesn't seem like it can be the source. Unlikely as it sounds, it could still be the receiver. I would get a receiver from a friend, and try that. If it was the speaker, it would pop regardless of the output it was hooked up to. If they were both bad, it would happen on both sides, not just the left output. I highly doubt new speakers will solve anything.

Zydo, same exercise you can repeat with receiver or whatever the suspected component is. sometimes swapping fancy wires to cheap wires also eliminate problem. it's risk free just to purchase and return within month to Best Buy.
