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 analogous to why hi-end speaker companies do not include speaker cables with their products."

Speaker cables may not be included, but some speaker manufacturers offer their own brand of speaker cables. Naim, Dunlavy, ProAc to name a few. A little company called Hammer Dynamics also had very specific speaker cable to match their speakers and it just so happens nothing works better.

"Most manufactures of high priced equipment do not include a “named” audiophile approved power cord"

LOL, Please tell me what a "named" audiophile approved power cord is. I need to know.

Insert any "name" you want i.e. Cardas, Synergistic Research, JPS, Nordost, Transparent etc..

Can you provide documentation to back up your statement?

Overall in this hobby, I think prices skew our judgment and ears, not to say expensive stuff does not sound better but the Yellow Eagle plug example by Gbart says it perfectly.

As to the OP question, that umbilical of the CP 700 looks a lot nicer than the ordinary looking network cat5 patch cable looking umbilical of my Bryston BP-20. I often wondered too about upgrading mine but it is hardwired into the ps so I will keep on wondering :)
