where do I connect the earth in my pre to?

My Lamm LL2 has an earth connection in the back, and a 3-prong power cord. I asked Lamm where was I supposed to connect the earth to, and the answer was not to worry about it - the earth connection is for US electrical systems only (I'm in Argentina). Yet I wonder what makes the US electrical systems different, and was wondering if I'm missing something by not having this connected.

So here goes my question: where should I connect this to? And what benefits could I expect?

Thank you!
Horacio

sorry, maybe I wasn't clear enough. Our local code also makes a ground mandatory, and my home has a pretty good ground (had a new one installed before moving in).

My comment about the ground pointed to why a ground and an earth connection? Lamm pres don't have built in phono stages, so why the earth?
I don't doubt the comment from Lamm is correct! Just wondering where I should connect the earth to. Water pipe? Anywhere? Ground in my power line?

OK, thanks for the feedback.

Al: that website is outdated. 3-prong installations are mandatory here. Also, it's not me using the term "earth"; it is printed on the back of the Lamm, which is a unit initially meant to be sold in the US.

I guess I'll forget about it: I don't experience any ground loops, no hum or hiss, except a little hiss I can hear with my ear to the tweeter and the volume wide open.
And I have no vinyl.

Thanks all for the input!
