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.

use the most expensive, fattest, grooviest looking power cord you can find - run it all the way back to your elec. co.s sub-station too

then pile Shakti Stones on top of it and sit back for the awesome!!

Randy / Although that would probably be awesome, only a few feed (directly attached to the electronic device) is required

Penns / I trust my ears so am not interested in Cardas cable or what Cnet states
