Pass labs poweramps


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

Same here with my 250.8 clinking sound about 20 minutes after being turned on. Haven't really stuck around after shut down to see if the same happens on cool down.

I called Pass and it is very normal its the heat sinks expanding no worries, enjoy the music.
