Which sounds best, 120 volts, or 240 volts?

I read all these reviews and comments that say how a new power cord can make a system sound better! Or different. With just a tiny adjustment, just a few feet of wire making audiable differences. I'm not disputing that, but it raises the question, can you hear the difference between a system powered by 120 volts here in the US, from a system in Europe that runs on 240? Surely that's a huge difference that should be immediately noticable. However it is hard to get a side by side comparison, most components needing internal adjustments to convert from one to the other, and of course the changing of input current. Different frequency too! From 60hz here to 50hz there, these have got to be major differences compared to swapping a cable? Any of you jet setters out there have an opinion on this? Do you prefer the sound on one side of the pond to the other?

@cleeds I presumed @joeylawn36111 meant the case of a component designed for dual voltage operation (or switchable between the two) in which case for a given power draw the current will halve as the voltage doubles.
Sorry, you are mistaken. At a given power draw, the amperage will halve as the voltage doubles. The current remains the same.

... the main difference is that 220V device  uses half the current a similar 110V one would.
Sorry, but this is mistaken. You're confusing current with voltage. All other things being equal, a given amplifier will draw the same amount current whether using a 240V supply or a 120V supply.
