Speaker make "pop" noise when pre amp turn off


Hi,
Does anyone have any idea what cause the speakers to make a "poping" sound when the pre amp is turn off?
Any remedies to this? It sounds fine when all the componet are on. The system does not have a hum problem. This only happen when the pre amp is turn off, or the amp turn off with the pre amp off?
Anyone has any idea?
Thanks.

Strange. I own an ARC Ref2 MkII but I only hear the 'pop' on the left channel when I turn off the preamp while the amp is on. Not a sound when switching to mute on the preamp. To avoid any kind of pop, I either use the mute switch on my Rowland 8T amp or put the amp on standby mode before switching off the preamp.
