Pass labs poweramps

Anyone experience little popping sounds after powering down their pass lab amps? I assume these sounds are the circuits shutting down.

Nothing in there should be making any popping sounds. Unless you're talking about the metallic ticking and popping sounds it might make as it cools down. My F5 will do that warming up and cooling down.

I have owned an x 250.5 for 11 years now and it will clink when it is warming up or cooling down. I think this is from the heat sinks expanding and contracting from the heating/cooling cycles of being off and on. It the sound is through the speakers then ya, a cap up the chain somewhere could be going or a tube
