Can upgraded power cords help my setup?


I have some KEF LS50 Wireless speakers and decided to use them with a Bluesound Node 2 via a Lifatec optical cable. Can I see a significant and worthy improvement if I swap out my power cords for something like Pangea cords? Do I need the AC 9SE MKII on the speakers or will the AC 14SE MKII be good for each speaker and also the Node 2 (C7?)? Power cords seem to be the only place left for me to tweak the most out of my setup.

Thanks for any input.

@pennsy,

This thread is no place for real electrical knowledge and logic. There's people here referencing Shunyata papers as proof of the science behind high-end cables.
make your own, their is no special magical spells being used by companies that can claim the one you made at home is inferrror. USe good quality cable, good connector and terminate it correctly.
The Neotech NES 3001 Speaker Cable which is 8AWG is what i use for my Power Cables Re-terminated properly with few diffrent connectors.

One can't help wondering if power cords are directional. Hmmmm.....

Ah, Geoff, good point - power cords are indeed directional, the power plug end goes into the wall or conditioner outlet and the iec plug end connects directly with the gear to be powered.  For best results, do not try it the other way around.
