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

I kid you not. They sell bags of rocks. 160. usd. My setup would have taken 1600.00 worth of "ROCKS" to load my speakers properly.

390. each x 5 bags x 2 = 10 bags of rocks for 1600.00 usd.. Nice bags though..  I like the idea, just not the 1600.00. OH They had "Earth Boxes" from 1k - 10k.. NO KIDDING.. Box of dirt.. 10K.
I'll take 5.. Keep the change!

Cabinet material makes a difference too.. My Elixirs are HDF. Go tap on the side walk.. about the same.. The monitor section, 390 lb..

I would not buy any of these items unless they have undergone cryogenic treatment and quantum cleaning. Be sure their astrological sign is aligned with yours.

Added mass for vibration control, can have a good effect on tubed units and power supplies. Good thing is that you can try and use something without spending a cent.

John Darko the youtube reviewer has them on all his equipment.

And the most important one, sits on the top of his head.

I prefer a more organic approach to mass loading (recent system pic)...
