What's this stuff on the back of a PS Audio Outlet

Hey I'm curious too. Post this over at the asylum, i.e. www.audioasylum.com, over in the PS Audio section. This should be interesting,

They might be capacitor's (or a simple network)to shunt noise to ground from positive and neutral.

The blue things look like MOV's (Metal Oxide Varistors) They provide overvoltage protection. The black square thing looks like a capacitor, probably for noise reduction.

The blue devices are Y caps used for high frequency filtering. They are connected between line to ground and neutral to ground. The large square device is a surge suppresor connected across line to neutral.
