The points you quoted from Roger Sanders' white paper are his conclusions, not assumptions.
They follow pretty much from this simple maths:
Let's say you need around 5 W RMS to achieve normal listening levels (whatever they are) with a low-ish efficiency speaker in a normal-sized room. Given that -- from unbiased sources -- we know some music can have a crest factor of over 20 dB, that means the amplifier has to deliver over 500 W peak power to reproduce that music without clipping.
That seems very straightforward and uncontroversial to me. Which of the two premises do you disagree with, or what is the fault in the logic?
