Pre-amps with seperate power supplies .....

I have a pre-amp with a seperate power supply that is connected by an umbilical cord. I am not an electrical engineer and I do not pretend to be one nor do I play one on TV.....I am pretty sure that there is DC current going from the power supply to the main pre-amp to power that component. Does it make any sonic sense to upgrade that umbilical cord seeing how that it is ''only'' carrying DC current ????? The pre-amp in question is a Classe' CP-700. I have asked this very same question to the fine people at Classe' and they said improving that cord would not make any difference.... So, I will ask that question here and also see if anybody has actually upgraded that power cord.

Unless a PC carrying DC is immune to RFI and EMR, unless the resistance of a PC is irrelevant with respect to speed and dynamics of transients, and unless the quality of the terminations is somehow also irrelevant with respect to DC, I don't know how the quality of the umbilical could not make a difference.

There is a reason why Tesla won out over Edison. I would think the quality of the cord might be more important for DC.
