Connection with stereo amplifier

[tfoust]

Help me understand the designed connection to a stereo power amplifier. 

If a banana plug to rca adapter cable is plugged into the speaker output terminals of the stereo amplifier and the rca end of said adapter is plugged into the Sublime rca inputs how does the stereo amplifier connect to the stereo speakers?

The speaker cable connects with a set of standard spade lug cables. That's why binding posts used to be called "five way" posts. Multiple connection methods mean you can connect spade lugs and banana plugs at the same time.  Also the hole in the binding post shaft creates yet another couple of ways to connect using bare wire or an old fashioned pin connector. And the least good way is to wrap bare wire around the post shaft and tighten down the clamping nut.
