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

Hello Rrog...thank you for your comment. I bought the Classe' CP-700 new and I am very satisfied with it and listened to some real good pre-amps prior to buying this one. The qustion that I proposed was ; ''the umbilical cord is only handling DC current ...right....and if you changed out the stock cord to another cord, would there be any sonic improvement ? '' Now, Classe' has already told me; no. There has to be somebody out there that has done this or also looked at this option who has some comments....and if someone was an actual electrical engineer said - your right, it is just DC current and the cord won't matter - there you have it ! Just looking form some input from others........

Also, nice to hear from you John!

Everything matters!

My preamp does not have an external power supply, but I used to use a Modwright Oppo 83 as my main source and it came with a separate power supply. I upgraded this umbilical cord and it was a significant improvement over the stock. I say go for it.

Hello Erndog...thank you and who built the cord for you ???

Rrog makes a very good point. Different isn't necessarily better. In fact, it could be that the designer experimented with various types of wire and found the particular configuration that he settled on to provide the best results. Second-guessing the designer with some other wire may actually hinder the performance.
