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

The community will benefit from my most recent article for Dagogo.com just submitted a day or two ago. It will take on the subject of mass loading and several other tweaks.
