A quote from Caelin on why NR PCs are required for connecting to components, at the component end:
"The design of a power cable can significantly affect the reactance of these signals within the power supply. The power cable is effectively part of the primary winding of the power transformer. The transition between the various metals used in a power cable and its connectors can cause electromagnetic reflections and diode-like rectification of the noise impulses as they propagate away from the power supply. If the power cable presents a high impedance to these signals they will be reflected back into the power supply where they will intermodulate, thus increasing the high frequency noise levels of the component. Most power supply filters are ineffective at blocking very high frequency noise components and much of it is passed through to the DC rails."

In other words, one of the biggest and most impactful sources of noise in a power distribution system is the power supplies of the components themselves.

The NR filters on the Shunyata PCs prevent this from happening, so that the power distribution chain stays as clean as possible from these noise components.
