I beg to differ but in my opinion, spade terminals are not superior to banana plugs!
I have known to trip over the my speaker wires with such force that the spade terminals either ripped right off the wires or damaged the terminal block on my speakers.
With banana plugs, my speaker wires just pop right off the speakers and I just plug them right back. I have always use banana plugs forever and no wires have ever been damage from their usage.
Any wires attach semi-permanent to speakers are prone to damage when being tripped over.
