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.

It`s true different and better aren`t the same.Can many audio components be improved upon? Yes! Grannyring is right in that lots of part choices are compromises by the builder to control cost and stay within a certain price target.Certain higher quality capacitors,resistors,wire,etc. wouldn`t be cost effectively for the manufactuer but can easily be improved by the owners of these components.Look at the standard power cords components are shipped with for one example of cost cutting.Of course the range of "part quality" compromise varies from one builder/brand to another.
Usually a very slippery slope regarding resale,sounds better and any other reason you want to use to mod/change a factory item.My attempts on that merry-go-round is a 25% success ratio,good luck,Bob
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.
