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.

dynaquest4,
Did you get this site mixed up with the Home Depot forum. The people on that site probably have as much interest in upgrading power cords going to their appliances as you do upgrading the wire going into your audio system. Just think of the impact you could have on that site!
Placebophile, really Randy # 11? There are apparently thousands of us around the world that fit into that category. To think we were all drawn into "the most expensive, fattest, grooviest looking power cord" actually sounding different in our systems. You have a lot of work to do & need to get this information out to the audiophile masses before any others are misled. 
Geoff / Good one

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

" High-end power cables are seriously a thing. I'm not kidding. If you believe changing the power cable in your gear will improve the audio or video...I have an island I want to sell you."

Since this is an audio forum, I'll buy the island if it improves the soundstage & midrange of my system the way the above mentioned power cord has. Also, it has to be picturesque, warm, sunny, not riddled with rodents or biting insects, spiders, fly's (etc.), and as affordable as the Oyaide Tunami power cord. Deal?   
In the last month & a half I've made a few power cords that I'm very impressed with using Oyaide Tunami wire (purchased from Chris at VH Audio) and Neotech connectors from Parts Connexion. The wire is $30 a foot & the ends are $25 each (they are a discontinued model from Neotech that retail for $70 each). All that said, you can make a very good 4' power cord for $170 plus shipping. These PC's replaced Pangea 14's & a 9 as well as some older Tribularies. They are better in every way, not even in the same ballpark. In regard to the statement above about updating your equipment instead of wire; I've been using the same phono amp, preamp, power amp, & speakers for 10 to 20 years (depending on component), & can tell you first hand that wire matters. I like the Oyaide PC wire so much that I purchased more of that last week to try as speaker cable. Pretty dumb huh, not... Although it only has about 30 hours on it now, that has also made a large improvement to the sound. That wire replaced Morrows SP5 cable, which is also very good. I should add that my whole system with the exception of the sub, is run through a very large Exactpower transformer so that could also be why the difference in wire is so profound. I really don't know, but the investment was worthwhile.
