Yes, I hear the pop/tick through all speakers.

Personally since I have tried other Outlaw amps and other Outlaw 990's with no effect on the problem, I've come to the conclusion that it's most likely a result of the power in the house having noise of some sort. Also, some times it's worse than others...

At one point the power was so dirty that the 990 stopped decoding DD properly, but since putting it through a Monster power center, that problem is 100% gone. Seriously, no power filter, DD decoding problems, with power filter, no issues.

Go figure.

If someone finds the same issue and a power filter that solves the pop/tick (or any other solution), please send me a note.
