Different components and ones of different brands react differently to an aftermarket powercord.
i disagree with the previous post and say yeah the amp is the #1 place to start with a cord.
Other than that, i would chalk it up to your preamp did not need the better cord as much as the amp did. It is the combination oof cord and powersupply i nthe electronics that makes the changes. Some more, some less.
i would not generalize about the changes lessening.
If i were you, i would go ahead a try the cords on other items in your system. See if some electronics benefit more than others do.
I use a pile of cheap Pangea powercords and have three different powerline conditioners and have swapped cords between the 9 and 14SE cords, and around the varous conditioners to find the best sound.
Some items do better one way or another.
