Connecting Amp to speakers


The humble banana plug, has not changed in its basic design since it’s invention, which I believe to be around 1929, many adaptations, but all following the basic design, so am I right in assuming this is the most efficient way to connect all these high end speakers and amps, which are discussed in these columns in great detail with their  perceived audio attributes, along with speaker cable costing mega bucks, and all connected, I am assuming, to each other by a banana plug. Maybe the top flight kit has an alternative connecting system??

I am lazy so I do like the ease of banana jacks.  Here is an audiophile test question:

Speakers frequently boast of having 5-way binding posts.  What are the five ways that speaker wire can be connected to such posts?

What are the five ways that speaker wire can be connected to such posts?

Bare wire

Banana plug

spade

lug

the wrong way

I have “locking” banana plugs on my Blue Jean cables. I feel these provide the best combination of surface area and positive connection. Erik is right about the spades, I have these come loose on my KEFs. 

I like BFA plugs, full surface-area coverage. Currently using locking bananas and am pleased with the connection over standard bananas.
