What has not been brought into consideration here is the need for periodic cleaning of the contacts and connectors throughout the system. From my experience after about 3 to 6 months the system became boring. A good thorough cleaning of all connectors brought everything back to life. The choice of spades or banana connectors will ultimately dictate the convenience of cleaning them. Set it and forget it? I wouldn't buy into that notion if you want to keep everything in optimal condition.
