Thanks to all of you who have responded to my requests ! I have taken the time to quickly review the latest post with links to a great education on power and grounding. Even though I'm electronically-trained, it was a terrific refresher and really summed up what and more importantly why I should use wiring that will reduce the possibility of adding stray and induced noise. It appears there is a lot of mis-information out there and "snake-oil". Perhaps the high-dollar in-wall power cable is good and helps with low-noise, however I believe my choice will be 10-gauge Romex.
Thanks again to all who have responded !
