You paid good money for your audio and video equipment. Experts think so. The better the equipment, the better the cable. Better-quality audio and video components will accept a number of different types of cable. Any cable made of aluminum wire is a poor conductor and should be avoided.
Thick cables are best.
But with speaker cable, the choice is yours. Good connectors are like gold, and the best ones are gold-plated to avoid corrosion. Some are even designed to resist coming unplugged accidentally.
