How does power cord affect a digital frontend?

I think it does, but can anybody explain why and how?
I could guess how current demanding amp may be affected by weak power cord, but what about CDP?

But what about manufacturers that are proud about their power supply design, such as MF, Simaudio, and others? It seems that under normal circumstances properly designed power supply is supposed to be quite immune to AC quality...

I'm not really clear how presence of noise in AC line may affect digital signal. It may affect an analog stage in CDP, but if the data is being transferred via SPDIF interface, the analog stage is not really involved... I realize that digital signal may be affected by 'bad' SPDIF cable, especially if source or/and receiver are not exactly match to SPDIF specification, resulting in jitter. But how jitter may result from AC power even containing some noise, it anyways is converted to DC for a digital stage? The digital signal is "formatted" by crystal oscillator, not by 60Hz wave.
