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

One of the cheap tweaks I would use was to open up a cheap CD player and coat the inside walls and top with plumber’s putty. It would add about a kilo of weight to the CDP and dampen (reduce) the vibrations.

On most players it would make an immediately subtle, but noticeable, difference.
