RE: Fools Errand.

"TK was getting awfully darn close to suggesting "if you make a cap big enough it is inaudible" by saying if there is no AC across a cap then it cannot be heard which suggests that the lower the AC across a cap the less it will be heard. Since bigger caps have less AC across them it is only natural to draw the conclusion that if you make the cap big enough it must be inaudible.

this is as much junk science as magic wire lengths."

I'm curious; which part of this are you saying is junk science? If we break it down, there are two main assertions here, I think:

1) That if there is no AC across a capacitor then it cannot sound any different from any other capacitor that has no AC across it.

2) That increasing the value of the capacitor will cause there to be less AC across it, and that if it is increased to a large enough value, then the residual AC across it will be reduced to the point where it becomes audibly indistinguishable from the case where there is zero AC across it.

It seems to me that statement (1) is really just a truism. Is there any room for disagreement about this one?

Statement (2) would seem to be pretty hard to argue against also. Or are you wanting to say that because of non-idealities in the construction of the capacitor, the AC across it cannot be made arbitrarily small by increasing the capacitance sufficiently? In any case, that is an objective question that can be tested by measurements.
