what is diff: Class "A", "A/B", and "B"


I am confused as to the meaning of the various categories of amps/pre-amps. Is a class A necessarily better than a class a/b or c etc. Would someone care to briefly list some of the brands that fall in these categories and why?
I know, it's a small question.
thanks,

At least some of the Pass amps are classA/B. The X 150 is class A up to 15 watts/channel, then slides over to "B" on up.
