It's a "grounding box":

This page talks more about why you really need to get one for your hi-fi system:

Ah, an "Audio Electron Black Hole".

P.S. What happens when it eats all of the "Audio Electrons" will everything become positive?

[coppercone2]

i wonder if you can get a connector on a black hole would it be a good ground, to put one near a planet and run a orbital litz tether to a black hole

perhaps a neutron star is more practical for now because the connector is easier
