Without getting too technical ( it's my day off) all XLR cables are balanced,stereo ( TRS,tip/ring/sleeve) quarter inch jacks are balanced,regular mono jacks aren't.Gold is technically a better conductor of electricity than nickel,however,it is also softer and wears off on stuff that is constantly being plugged in and unplugged.
Soooooooooooooooooooooooo,apart from the colour ( you bought a blue cable????) your cable is fine.
