Thanks for your comments. As you pointed out, it is very complicated. Nothing is isolated, everything in the amp, from the input through to the speaker, interacts and affects how the amp performs. Frequency is important. How hard the amp is being driven is important. When designing an amp, there are some general guidelines that hold true.
My point was simply, low end demand on the power supply in a bass amp lowers the reservoir and, if it can't recover, causes the supply to sag to the point where it is a factor in the onset of distortion. The smaller the reservoir, the less able the amp can cope. Increasing the capacitance of the first reservoir cap is one way to reduce the sag.
