I dont know how to explain this, but i think some larger cables perform better than some small ones and vice versa.My current system sounds best with heavier guage cables,but my last sounded better with thinner cables including the power cords.I know most inwall wires are 14Guage,so why would I use 10awg power cords from a 14awg wall receptical?The same reason why most heavy duty power tools use heavy guage power cords,also the same reason why many audiophiles run 10awg speaker cable to speakers who's internal wireing is between 14-16awg.The same goes for heavy guage interconnects that will plug into a component who's internal wireing is only 18-20awg.All I know is well designed heavy guage cables are excellent in the right system,no matter how thin the inwall wire is.
