Drubin,
Excluding the power input, the entire audio system IS a series of components ("chain"). Just try upgrading everthing but your 5 watt/chnl - 10% distortion amplifier, or everything but your tiny Radio Shack speakers, or even 24 AWG speaker wiring into your new Wilson Watts.
Same thing goes for your AC supply wiring. To small of a gage, and see how that 300 watt/chnl high current amplifier performs during heavy bass rifs or explosive LFE. Sure a larger gage of 3 foot power cord is better than 3 foot smaller gage Romex, but barely makes a difference over a 35 to 50 run of inadequately sized Romex from the breaker box.
It is JUST a descriptive phrase.
