I beefed up the power supply in an Audire One back in '76 boosting the capacitance from 20000 uF to 80000 uf via an external cabinet and using a higher current bridge rectifier. Unit was more dynamic and more transparent sounding. And would play on about thirty seconds upon power down! I later did the calculation and determined it had about the same energy storage in joules (100) as a later Threshold Stasis 3 with similar output.
[end quote]You didn't just add more capacitance. You also added an inductor to the circuit with cable length going to the external capacitor. So you have created a resonant circuit. Where it falls inside the audio band requires more information followed by testing. It may be significant or not.
If you are going to play Electrical Engineer, at least learn some of the basics.
Furthermore, the Frank Van Alstien I know does not share you ideas on power supplies. In one of his famous Audio Basics articles, I think I can find it, he got into quite an exchange with some audio reviewer. The reviewer liked one of Frank's products but claimed the power transformer was too small for optimum performance. Frank set that straight based on well known electrical principles.
