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.

EVERY time I read a power cable or speaker wire thread the same conclusion is drawn-
The o.p. learns to-
 NEVER ask the question ever again because there is no
"correct" answer.
Blockheads are those that speak out about topics, either positively or negatively, without any actual personal experience, almost always citing what un-named "expert" sources have supposedly told them. Like looking in a mirror, aye, helomech? The italics were a nice touch though.

Almost every seller offers an in-home trial audition with a money-back guarantee. Try a couple of the good ones (Pangea is not one of those) and then report back with an opinion that has something to offer other than your indignant and unqualified speculation.

The most common problem that happens with house AC interfering with audio is DC offset. Yes, you can have DC offset in an AC line. It happens during peak consumption hours. Try this, does your system sound better at certain times of the day? Say early in the morning or late at night? A new power cord will not solve this issue, and compared to what's in your walls a common hospital grade cord is plenty for audio equipment. Like other's have said a PC does not in any way reject the type of "contamination" you would actually hear to get that "pure" power.  
Upgraded power cords helped every component I upgraded...some much more obvious than others, but all to at lease some degree.
I have Pangea power cords on my system and I am extremely happy. The AC-9 and the upgrades are for your power sources... amps, integrated, etc. The AC-14 and the upgrades are for your source components... turntable, network audio player, etc.

It's worth a try, you have a 30 day home trial to decide.
