Since the supply impedance is in series with the output circuit, I can't imagine an engineer disregarding the potential effect it has on sound. I mean, the filter caps will hold a charge so maybe that's why he thinks the PS tube impedance doesn't matter. But even if the capacitance is large, you still have an RC constant there with the tube playing its part. Seems to me the effects would be measurable.
