Class A amps run hotter, go through tubes quicker, are less efficient, but have a more complex compressed vintagy tone, and are brighter sounding with a typical glassy tone you just can't get from a Class A/B amp - Class A/B are more efficient, run cooler, and are arguably more 'dynamic' sounding with a punchier, tighter feel.

Nice techy articles here: -

This one explains why the AC30 isn't true Class A: http://www.aikenamps.com/VoxAC30classA_2.html

And this one discusses a related topic of power-ratings:
