Don't cheap out like I did with 3x 10ga romex lines. At least spring for cryo-ed romex, but I'd suggest either Hidden Treasure or AP Oval 10, so you're not tempted to rip out your walls again later. I think non-cryo romex has a sound too, 12ga is more balanced, but 10ga while better in dynamics, seems to have a hole in the lower-midrange to mid-bass. Definitely get good outlets, I'm planning to install an SR purple to see what it does for my EQ hole as compared to my Furutech GTX-R. The newer GTX-R with NCF is supposed to be more balanced in EQ.
I don't have analog but do have a large HT system built around 2-channel, and haven't noticed any noise from using 3 outlets. If you do multiple runs, ensure that all are from the same hot leg. Let us know how it worked for you! This and the thread on surge suppression are timely for me.
