Watts are watts, Class A, AB, or D. The advantage Class A has over Class AB is no switching distortion, as the power output of the transistors is always on. This has nothing to do with power output though.
Class A Watts
Are class A watts more powerful then class AB, or is a watt just a watt. In other words would a 100 watt class A amp struggle with speakers that a 200 Watt class AB amp can handle just fine? I guess current would matter as well. Anyway, I was just curious.
