I used to worry about his stuff. TBH now I listen to the music more than I worry about it. If it doesn't work and there's no sound, well then I will take a look at the connections and the bananas or speakons or screw terminals but only then.
Before seeing the light on the road to Damascus, I liked copper buss bar or grounding braid for my conductors of my speaker wire. The heaviness of my wallet is so much more thrilling than the other more expensive cables. As for binding posts, a set of screw terminals seems to work fine or speakons in a pinch as long as you regularly connect and disconnect the Speakon so the wiping feature does it's job. If you're super worried about it, just solder your cables directly to the output pads on the circuit board of the amplifier and directly to the crossover (if you use a passive one) on your loud speaker.
