Koralia 550?

[Supra]

When I unplug my 550's then plug them back in sometimes they do not go back to full blast. Anyone else experience anything like this? I have to unplug and replug a couple a times to get it to work right.

Nope, but mine isn't very old either. Hasn't had time to get gunked up. Maybe it just needs a cleaning?
