RE: Fools Errand.

"Show the answer then. seems simple enough. Do take pics. Are you sure 1F is enough? How carefully are you going to be measuing AC( or lack of ) across it?"

It's really just an "thought experiment" or idealisation. No matter how small the ripple voltage V that someone would find acceptable is, there always exists a sufficiently large capacitance C such that the ripple can be reduced to being less than V. If 1F isn't enough, make it 1000F or 1000000F or whatever. That's the beauty of thought experiments; they don't need to be realistically realisable.

Of course there would be no difficulty in calculating the order of size of C that would achieve the desired outcome. There is really no need to carry out an actual experiment.

Actually, for the case of a power supply, I suppose a perfectly realisable (if somewhat inadvisable!) way of reducing the ripple to levels that would surely be unambiguosly small enough for anyone's purposes would be to connect a string of car batteries in series.

But again, these are not things that one actually needs to achieve, or wants to achieve; just a matter of establishing the logical point that the ripple can in principle be made smaller than any specified level.

As I said earlier, the original question raised by the OP was concerned, rather, with the difference in electrical characteristics of a new capacitor (of normal, realistic value!) versus the same capacitor after some period of "maturation." The discussion can then be broken down into two parts; firstly, how to measure differences in characteristics as the capacitor ages, and then secondly, to understand the physical changes that are taking place in the capacitor that account for this. These are quite interesting questions, and for me at least, they are much more interesting and concrete than anecdotal accounts of people's listening experiences which are subject to so many uncertainties and confusions from expectation bias and psycho-acoustic complications.
