Earthing Home Cinema Kit

Any electricians in the house?

While reconnecting my Home cinema set-up recently I noticed that ALL of the components have two pin mains connectors - none have a connected earth wire. Do I need to find a way to create at least one Earth in the system - I know not to create an earth loop.

If equipment has a double hollow square on it then it doesn't need an earth.

That means it is double insulated. I thought some electronics needed a good earth to stop noise - rather than for the "Earth as a fault protection" system.

If so there should be a connection for it. Usually a binding post with a thumbscrew.
