just not necessarily right either :-)"Pure" is really a modifier that hasn't much meaning in this context. It might have been used at one time in an attempt to separate the shadier advertisers from the more consumer friendly advertisers, but nowadays it is just an advertising term. In the end, not many amplifiers, regardless of class-A "purity", consume the same power at idle as they do at full power, and at all loads. Bias levels change and adjust, and banks of transistors still change bias in most push-pull designs at high power levels when they aren't needed, unless it's just a resistor biased single-ended design like some of the very low power class-A amps.
