Back on topic, until we see Speakons are on the rear panel of receivers, I guess bananas are as good as it gets for consumer gear...

Bare wire has it's fans, but I use bananas because IMO, they are a more consistent connection with a lower chance of stray conductors shorting together in the tight confines of a multi-channel amp or receiver.

Also, I like the solderless AudioStream models that have their own insulating sleeves that can be changed from the front without re-terminating the wire. Nothing is more frustrating than having to take apart a connection because you forgot to run the wire through the insulating marker in the proper sequence before soldering.
