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.

I obtained my undergraduate chemical engineering degree from Manhattan - I worked in the pharmaceutical field developing drugs a few of which were successfully brought to market. This required learning about and becoming proficient in computers, electronics, electrical systems, all types of control systems, a LOT of mechanical systems.
You can say I've got a lot of processing experience.
Well said tjassoc, but way too much effort for a couple of blockheads who have obviously never tried quality power cables but only "think about it"...

 I said No. Because you talked about this wire Panaga. Thats why its on sale.  Try that wireworld 
But you need to spend some money.

"Well said?" What did tjassoc say that proved anything? Quite the contrary in fact. A power cable is not going to dissipate "contamination" from a light dimmer, or any "contamination" that made its way to the outlet. It's the same garbage that perpetuates through these forums by those who claim to be jack-of all-trades engineers. 

I've worked alongside actual electrical engineers who have been dealing with electrical noise issues for 40 plus years. They laugh at all this power cable nonsense, but I guess they're just a couple of blockheads.
