Wattagate connectors

Wattagate has the normal brass plated connectors as well as the gold plated ones. I've heard some say that the gold plated ones are slightly brighter sounding than the brass plated. Wondering about this.
Appreciate your thought or opinion on this matter.
Thanks in advance.
Hello.....As a long time user of the Wattgates and one who likes the option of interchanging cords and connectors I've had considerable trouble with the screws stripping out on the Wattgates,even with moderate torque.If you want to try a better plug check out the Farutech connectors.Contact Jim at Harmonic Tech to purchase direct.These are the best I've used and are reasonably priced!
Actually the gold plated are supposed to have a warmer sound.
