@ boxer12 It doesn't matter! It's all the same science. Regardless of the application. An outlet does one thing - it makes a connection to transfer current from a source to a device "nothing else" the only thing that matters is conductivity, a good connection and quality parts and assembly, in an AC - 120V outlet - the cost is about $20.00, not $500.00. The same applies to cords and cables. I've been into audio for about 40 years and have listened to about every cord, cable and outlet out there - some things are fact and others are total BS...Jim
