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 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.



Someone / something is most certainly getting things mixed up - I'd like to converse with the senior electrical engineers you're referring to.
After about an hour of discussion, there would certainly be an acknowledgement of proven fundamental scientific principals and properties. It would also be entertaining to let them enjoy some well recorded music while blindly switching power cords in a modestly high end system.
My 2 cents.
Pick your cable manufacture, then look at the used market and go for the highest one in their line up that is within your budget.
Also look at upgrading your outlet and last but not least
for a dollar or two each replace the glass fuses for ceramic ones.

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.
