I just read an older article again entitled, Power Amps: Terminology, that was in the February '02 issue of BP. Class A, B, AB, D, G, H and T.....Is one better for bass rigs than the other? How does the slew rate, damping factor and switching(power supply and on the output stage) affect the performance of the amps from these different stages? My power amp is a Class H variety with a switching power supply. It sounds great to me but I never considered any of the things that I listed above prior to making my decision. What factors should we look for regarding making a decision about a power amp?
