Romex power cable as speaker cables?

I've always said that copper wire and Romex of various gauges is a good expample sound pretty darn good. People don't seem to want to take the time to audition the concept.

Solid core wire is usually a good conductor for interconnects and thick gauge is great for speaker cable. The less the stray strands, the less they can interfere with the signal transmission.
But, Romex wire uses the cheapest form of copper. The concept is good but the quality is just not there. IMHO.

I actually made (2) 12 foot lengths of pure soft annealed 9999 12 gauge silver wire and it sounds great. But this was before the silver prices got crazy expensive.

I know of at least 1 mega-bucks speaker company that uses solid core, electrical wire for their internal wiring. 

Saves on materials, but adds significantly to the time needed for assembly. 

I don’t use it for my main, but because I had to carry the signal 60 feet from my system to my in ceiling kitchen speakers, I figured it was worth trying 10 gauge NM wire. The sound is a little bright but I think that’s more the speakers, and the fact that they’re in ceiling, than the wire. 
That said, later on, when I Upgraded my main speakers, I bi-wired them with good AQ cables.
