Can a better power cable make a difference if NOT plugged directly into an outlet?

@vthokie83 agree with everything you said except the thought about furutech rhodium. I use furutech rhodium plugs on my power cables as well as furutech rhodium NCF outlet. Very extended and sweet highs, great clarity. Zero harshness. Perhaps the harshness comes from the components in your system but not from the outlet. 

@hilde45 changing a power cable on a component would make a difference. Doesn’t matter if it’s plugged into a power conditioner, power strip or outlet. Pangea is pretty basic. I wouldn’t hesitate to step up to something better. Boils down to how much you are planning to spend and what component would get an upgraded cord. I would start with the amp if it isn’t possible to upgrade the power cord on the conditioner or power strip. As with everything in this hobby, step up to something significantly better. No baby steps - don’t waste your time and money. 

@hilde45 I have used several different Audience power cables over the years. Starting with their original AU24 powerChord. Excellent cables that work well on DACs (medium power AU24se) and amps (high power AU24se). I was not as impressed with their lower end Forte F3 though.

I like your plan to step up significantly. That should make the difference more obvious. 

F3 is ok. I would skip over it though and go to StudioOne. 

Hahaha. 
All jokes aside, going from one sub-$200 cable to another will get you very little ROI if any at all. I’d go for a used Audience AU24se power cord. StudioOne is a replacement for it that uses different connectors. The older se is a great cable. No need to spend $1500. 
 

Good plan. It will be very nice on your DAC as well.
