What are all these metal cans/pods sitting on top of electronics?


John Darko the youtube reviewer has them on all his equipment. I see them on alot of people's electronics it's a tweak of some sort I just don't know what they are or what they do. 

Thanks,
Steve

I mass load my tiny novo headphone amp with a decorative bronze statue of a mermaid sitting on an amber colored marble base, very nice looking and heavy. Only reason is the amp is light weight and tends to be pulled on by the interconnects. Now its steady and planted like a rock. Does it sound better? Hell if I know.
