Dracule1, I speculate that main reason to add bypass caps is to improve frequency response and to lower the noise. To combat ripples you need to increase main capacitor and/or reduce its ESR.
As for self resonance - you want it as high as possible because it is the point where capacitors starts behaving like inductor (inductive reactance larger than capacitive reactance) meaning start of impedance increase with frequency (lowest impedance point). You don't have much control over it unless you use different capacitor type.
Increasing main capacitance will reduce impedance but also reduce self resonance point. It might be necessary step to combat ripple but does nothing to improve frequency response needed to lower the noise or improve load response.
If your main capacitors are film type then you most likely won't have any problems with load response within audio frequencies hence bypass cap will be oriented toward defeating high frequency noise coming from power supply. For that you need much better capacitor with much higher self resonance point. We are not talking about harmonics of rectified AC but about high frequency noise on power line.
I'm not sure what he means by amplifier's "end"
