"Who wants sag / noise in a hi-fi PSU?"
A tubed rectified, critical inductance power supply, with the appropriate amount of capacitance, feeding a Class A circuit will not sag and is as quiet as a power supply gets.
"In terms of ragged waveforms, solid-state diodes are the worst, followed by Schottky diodes and HEXFRED's, followed by conventional tube rectifiers, followed by TV damping diodes, which are the smoothest of all in terms of the AC waveform on the power trans secondary."

"Conclusion: This is a set of personal preferences"I think Lynn meant the article as a whole.
Lynn has worked for major firms and is very versed in the science behind audio electronics.
What he says about power supply noise is not his opinion, it's fact.
There are plenty of things in this hobby that are purely subjective but physical facts are physical facts.
That doesn't mean that everyone will like the sound of a stable, noise free power supply but scientific fact will tell you which ones are stable and noise free and which ones aren't.
