I've been using a Rel Stadium 2 for over 10 years and just added another one (big improvement with room node reduction and increased smoothness overall) but I called Frank at Signal Cable, told him the length(s) I needed and he made me custom lengths to replace the stock Rel cables.
*Dramatic difference? No.
*Well worthwhile in extra dynamics,speed and detail: yes.
Am not familiar with the brands/models you've mentioned so I can't compare but changing from the stock cable seems a likely improvement... FWIW, I will never use stock power cords nor will I buy any component with captive power cords unless I swap in an IEC connector to allow aftermarket cables as the improvements are profound; but that's a whole other can of worms not worth opening. Good luck.
