Snap Crackle Pop HELP!!!!!!

[4drums]

We have a Rotel 5.1 amp and processor in use for three years with zero issues .
Last night from the rears we noticed what can only be described as a high pitched log fire. Disregarding as a cable sound source, we ignored and turned off the system. Tonight, after a rough day at the circus, it was movie time. All speakers had the same sound as the rears did the night before. Nothing has changed in three years, so the investigation was on. First step, change the source,same result. Disconnect each component from the power conditioner to see if there was a culprit in the chain. Same result. Remove the power conditioner and plug directly into a power strip.Same result. Run a commercial duty extension cord and plug into another power source (another breaker). Same result. There is no hum or buzz indicating a grounding problem.
Before I hire a crane to move the amp and lift the front wheels on the Civic on the way to the repair shop, did I miss something? Did the Rotel say no more to action movies?

Appreciate any help.

It does sound kind of ominous. Have you tried resetting the unit if it is indeed resettable?

Does this happen with all inputs to the Rotel? If so, it is the Rotel's digital processing most likely. Can it do analog input, bypass the internal digital circuits with the same results?

Thanks for all the reply's.
The unit is only resettable by turning the power off and hearing the clicks.
Yes it happens to all inputs. Cannot by pass the circuits , everything is processed. Did not check the analog input, but even without the source being turned on, the system still pops. After thinking more about this the arrows are pointing to the proccessor.

You may want to double check this by disconnecting the interconnects to the unit and have only the speakers connected and the unit on. If it still pops, you have the answer, someplace in the unit. Maybe a cap someplace going bad, leaking, who knows, or the processor gone hay-wired.

OK, don't keep the solution a secret though. How was the problem solved?
