Let's talk power cords

" From your circuit box to your wall outlet, you have cheap 16-18ga or thinner, depending on your builder , electrician, "

It is my understanding minimum gauge size is 14 for Romex.
------------------------------------------------------------------------------
"how does connecting a 8 ga of wire from already 200ft or whatever the run is, make it sound more powerful, or put the biggest stretch I have ever heard, the air around instruments?......really :)"

Try it, you will be surprised.
---------------------------------------------  

"if you have a nice 220 dedicated, with 10-12ga runs to your outlets, it may make a difference, but I doubt it."
------------------------------------------------

Oh, it does, I did that when I had a dedicated listening room. I used 10ga. Romex, a bear to work with, but one of the best upgrades I ever did.

@arcticdeph, from my circuit box to my dedicated outlets I used 10 gauge wire.

I also used 10 gauge wire to my dedicated circuit box. 

Damn, you guys don’t mess around!
 Very good idea, expensive, out of my league, but for audio, it is an excellent++ idea.   Wish I had the deep pocket for it. 

 Jealous!

i would try to use a power cord, but I can n to justify 200 dollars for a 3 foot piece of rubber, flexible cloth, and a small copper wire in it. 
  I just stick with what the mfgr supplies. 

Still jealous. ;)

Nothing wrong with that arcticdeth, the only important thing is to enjoy the music! ;-)
