Ungrounded power cord: Will I die?

Herman, my Japanese amp came with this power cord that has a two prong male end and three prong female end. Since it was manufactured this way does that mean the cord is safe? Japanese household electricity is only 2 prong. Is there something about their electrical grid that is inherently more safe so that household devices don't require a ground plug? Is there something about Japanese electronics that make them more safe? Also, why the heck does a Japanese amp have a three prong female end when they don't have any three prong outlets? I know mine was converted for American 120V, but pictures of Japanese 100V show the same IEC plugs. There are lots of American devices other than wall warts that use 2 prong plugs that aren't necessarily plastic. A floor lamp comes to mind. If it is so hazardous to use an ungrounded power cord then why isn't it required for ALL electrical devices in the US?

Anyway, a 5V output DAC PSU doesn't strike me as a high powered device so I think I will just take the risk.

"If it came with a three prong plug then safety standards dictate it should be there"

OK, so since my amp came with a two prong plug it should be safe to use with the amp even though the amp has a 3 prong inlet?

I guess even if the amp is safe to use with an ungrounded cord, they might put a 3-prong inlet for use with all of the other aftermarket power cords out there.

So the moral of the story is: It depends on the device. Stick to what it came with.

Inna, not sure how you interpreted my post that way, but I am definitely not asking for advice on how to get electrocuted!

I think I'll take my chances on using the Luxman cord with the DAC. I will probably upgrade in the next year or two anyway. I'll just put a piece of masking tape on it that says "TOUCH CASE WITH INSULATED SCREW DRIVER BEFORE HANDLING!!!" in big letters. How about that?

In my apartment circa 2005 ALL outlets were groundless and needed cheater plugs. Is this illegal? (California) If not, why would that be allowed if potentially lethal from everyday use? My guess is the worst that would happen is getting "zapped" as aforementioned (never knew that used to happen... crazy), but nothing life-threatening.

Can you tie a floating chassis to a grounded chassis with a speaker wire?
