Why do I need power management if I have a great power cord?

Isn't it kind of unnecessary to additionally add a power conditioner if I have an expensive audio file grade Power cord connected to a component?

So you buy a Power conditioner from a hi-fi store and they say oh, you need a really good power cord to go with that and then another one to go from conditioner to the component. Do you need it all and why? Seems the last couple of feet before the component should be more than enough.

Exactly so, A large,  fast,  over spec’d capacitor bank in a power supply is the key. 

“ 

The capacitors only get filled up when they are at or below the voltage coming out of the transformer-rectifier-regulator. That physically is happening in a rectified sine wave that operating at 120 Hz. So there is a great deal of time (maybe a 1/4 of the time), where the AC is NOT feeding the capacitors any DC.

The power supply in an amplifier is holding DC and buffering the AC to provide that energy reserve..“
