OK you got me, they are a brick, of iron that somehow, creates a magic field of magic? I'm not getting it.. It does something, other than weigh a lot? Grain oriented, does it expand or contract the fields or something in a different way, run as shielding? It's 40.00 of postage? I don't get it..

What is it?

Don't start something and not finish it.. What is that thing? I GOTTA KNOW NOW!.. What is it.... :-)

I have had 3 of them in my system in various places for decades. When one of them goes missing it is usually because my wife needs to glue something. 
I didn't mean to be mysterious. I bought them because a dealer that I had a relationship with at the time in Princeton NJ recommended them; and while he was a bit quirky, he had a genuine talent for putting together really good sounding systems, so I bought them. He said that I should place them on, or in the closest proximity of transformers, and that it would have a beneficial sonic effect. I can't swear that it does, but I have always used them that way, and I also use one in the middle of my DAC which is not evenly balanced.
