What is the best order to upgrade a power cable loom? Thanks.

I'm about to upgrade my power cable loom from the out of the box, generic cables for two channel stereo.  I have been told the best order, or descending priority order, is first upgrade the power cord from the wall to the power distribution strip, then the pre-amp, then the integrated amp and last the turntable.   Please do you have any thoughts and/or experiences?  Specific thoughts and/or experiences with Nordost?  Thank you in advance! :-)
