What is the difference between a high current amp and a class x amp?

A high current amp is just that, an aplifier that is capable of producing a very large amount of currnet. When an amplifier puts out a specific voltage, the lower the impedence of the load is the higher the current required. So most high current amps would be stable at a low impedence, like 1 ohm per channel. A class X amp is similar to a class D amplifier (don't really know much about them). It is a digital type amp that is very efficient, but arguably would have some effect on the sound quality. As far as I know, the class of an aplifier (A, A/B, D, X, etc) has nothing to do directly with the amount of current it can produce.

high current is basically a marketing term. It's accepted definition is an a/b amp that can drive lower than standard (4 ohms mono) loads.

They're another level of efficiency below standard a/b amps as well, with class d, t, & x on top, a/b below, and high current a/b below that.

IMO, if you're looking at a high current amp there's probably a class D available that would do the same job and be more efficient doing it.
