Just to be clear, I don't think the op's q has been answered, and that that is that there is no explaination as to how a PC can change the frequencey response of a device.
Easy question, easy answer!
One point is most power supply designers will assume they can design in any properties that a power cord may add to the mix, essentially negating the PCs affects to the sound. But that would eliminate the revenue source of many vocal suppliers and buyers, so that point is not well taken.
I guess an alternate approach is to modify your existing equipment's power supplies, which manypeople prefer to take.
