I'm sure that the use of 60Hz power on these amplifiers is just fine. They probably use switching supplies, so the input frequency is of little consequence. Usually, unless the input frequency is used for timing of some sort - like in some video equipmemt - the different frequencies aren't a problem. Of course, AC motors run at a different speed too, so that can be a "timing problem" of sorts too. But the point is that while I'd check the documentation to make sure, I'm pretty confident that these amps will work just fine on either 50Hz or 60Hz power.
