@jea48 - interesting read, but the problem I had did not relate to ground loop buzz / voltage inducement. I believe now it had to do with the voltage in the tiny 14awg wire being restricted by the high dielectric constant on the insulation (something I have definitely found on small gauge wires). On a larger 10/12awg conductor, there is less percentage of voltage restriction with more area/mass of conductor. My result of 2x14awg romex was weak bass/midbass punch. A single 12awg gave much better impact/sound.

I did testing with a double-run of 14awg romex (that's 2x14awg which makes an 11awg totalPlease describe the 'test' in detail from start to finish
Unless you were able to compare the original to the new, in real time, any perceived change is pure fantasy

Gimme a break!
As far as the 2x14awg romex test was concerned:
1. Take two 50 foot lengths of 14awg romex.
2. Take the two black hot leads of both cables and connect them to the same 15A/20A circuit breaker.
3. Take the two white neutral leads and connect to neutral bar in sub-panel.
4. Take the two bare ground leads and connect to ground bar in sub-panel.
5. Run the two 14awg romex cables to outlet.
6. Connect the two black hot leads to hot connection on outlet.
7. Connect the two white neutral leads to neutral connection on outlet.
8. Connect the two bare wire ground to outlet ground.
So, essentially, I am doubling the size of the wiring from circuit breaker to outlet. This is the same thing that happens inside larger power cords.
1. Take two 50 foot lengths of 14awg romex.You'd need to check NEC on this as well as your local code. Also, note that only breakers designed for such a two-wire connection would be permitted.
