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.

You may find that just decent audio powercords which don't have to be costly will work well with a switching power supply.

I found expensive or good cords don't seem to work to the advantage in the switching supplies and not as critical as when used with linears supplies.
I have found the lower price Transparent and older Audience to be good value power cords
@justubes2.... I find your comment about PC's with switching power supplies interesting, Not really something I had considered. I've been on the fence for quite a few months, as to whether or not I should upgrade my PC's? My main reason for considering this is that the IEC connector on my somewhat high end DAC/Pre, does not make a snug connection. I'm a firm believer that any positive improvements made by PC's, are solely based on the quality of the connection, gauge and shielding, nothing more. My amp does have a switching power supply, so I'll will have to look into this more.
@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.
