"I was already fully aware of all that you wrote...."
So you agree that the DC resistance of your preferred power supply is greater than that of the one you are comparing it with?
But you didn't address my main points:
1) What do you mean by "resistance to the 300B Finals Filter"? The figures you presented are just the sum of the DC resistances of the chokes. But why would that figure, of itself, be significant? The transformer secondary and the rectifier are also in that circuit.
2) A stepped load is not representative of the power demand from an SE amplifier. The current draw by the amplifier is, on average, constant, with the timescale of the fluctuations being the timescale of the frequencies in the audio signal. So what really matters as far as the amplifier is concerned is the output impedance of the power supply at audio frequencies, and how that impedance varies as a function of the audio frequency.
