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.

@asahitoro - the Node-2 responds very well to good cables -  IC's and PC's.

I used a C7 figure-8 adapter, but eliminating the adapter and installing a Figure-8 plug  proved to be much better
- I bought a figure-8 plug on the web

Some very good PC's are made by KLE Innovatons - contact them to see which ones would be best for your system

Otherwise - Signal Cables are very good value

It really depends on your budget?

@chewie70 - don't forget about cable geometry. That plays a part in the performance and 'sound' of a cable as well. Even power cables. 
+1 for @Toddverone point - the right geometry is an essential element in achieving the best performance from any cable - i.e. IC's, Speaker and Power.

be sure to use a geometry matched to the coriolis force vector for your latitude
That was actually really funny Randy. C'mon though. There is loads of established theory regarding cable geometry and its effect on noise rejection, capacitance, inductance, signal integrity, etc.
