Another voice from the wilderness: A point seems to be missing here, and that is the particular component the pc is plugged in to. A pc only supplies power and filters the RFI/EMI. The component makes the sound. If cleaner power makes for "dirtier" sound, then the component doesn't necessarily do well at low level detail, which is what is being brought out by the quieter cleaner background. Is it possible to be too quiet?!
Everyone's experience seems to be different. Everyone also focuses only on the pc. I suspect it is the synergy between the pc and component as whole in one's own system that is important.
