More Voltage = Less Amp Draw?

[BrianG]

I think the general assumption is that if you use high voltage, you also have to use a high turn motor to reduce amperage.

People using HV setups are trying to do one of two things: 1) Have a VERY high power setup without having a ridiculous amperage, or 2) be able to reduce current draw on a more typically-powered setup so that losses due to high currents are reduced.
