100v,115v versus 230v

"240 Volts is no joke."

But it is undeniably memorable. I lived to wonder if I had used all my life credits just on those events.

I am puzzled by the post claiming someone died after licking 9V battery. Is there any kid who has not done that? 4.5V is softer, but 9V should have not killed anyone just because of the battery.

Every one in the USA has 240 Volts @ the pole YES. They had it Be for Millercarbon was on the earth....

Granted. But I fail to see what my time off Earth has to do with anything.

That is just rubbish unless you have an amp which consumes more than about 1500 watts. Then the standard 120 volt wiring may not be adequate to carry the current. Other than that there is no basis for the claim. 

@ditusa , I thought you were living in USA, voltage sensing or switch mode power supply/analog switching amps just like Nuforce design amps works any voltage worldwide are not my main concern. I'm moving to USA soon ,planning to take all my gear with me do not want sell my we91 amplifier which is 240 volt that's why raise the question , in my humble opinion audio equipment regardless of how hungry or not performs better 240 volt operation.
