Way to squash the capacitor party, John.
On a serious note, there is a common belief that a less than LARGE capacitance reserve might be completely depleted during loud and/or percussive passages, leaving the capacitors sucked dry and unable to deliver for the next passage. This isn't the case, as stated in the first article you linked, copied below:
"With large capacitors, the momentary current peaks created by the program material will not be of sufficient duration to discharge the caps to the full load voltage levels, so there is more voltage available on a more or less consistent basis. This equates to more power for transient signals, and lower ripple voltages the rest of the time."
