    Yes class A is faster, that would be accurate because it's on 100% all the time. That why it's more hi-fi sounding.

    It is the rate of how quickly an amplifier can respond to a rapid change of input level. This is measured as a change in voltage with respect to time.

    Class AB has a gating affect, the colder it's biased the more noticeable / slower it becomes.

    OK, let's take an example. A 25W Class A amp and a 50W Class AB. Which is faster to 40W? (Silly question but since you are going down that road). Also on the gating effect. Can you show where you get this theory from?

    On the article, which I just skimmed,

    Not the greatest description but not too bad.
