Bananas rule, spades drool. End of discussion.

@glennewdick I’ve had both WBT and Furutech locking bananas. I’m not sure if the Furutech’s I got were fake or not but the WBT’s were absolutely better.

The Furutechs were made of thick pot metal, deformed when expanded, and the diameter of the banana was rather on the small side.

Another A’goner recommended these, and I use them exclusively. The spring and barrel construction is pretty thoughtful. The barrel ensures a long wide contact with the socket, and the spring keeps it plenty tight. I have 8 of these with heavy cables pointing straight up and they are just as tight now as they were 2 years ago.  For safety you really must use the heat shrink sleeves which are included.

It is when two spades at once atop one another have to be installed that I find the problems with loosening start. The likelihood of two stacked spades coming loose in time is much higher. My Rel subs require such a connection ("high level,") and I have to check on it periodically. Recently though I added a new power amp to the lineup that made the Rel's play too loud at even low settings on the volume knobs. Rel's advice in this situation is to use only one of the spade connectors and tape the other spade. Much better on all counts

I test a lot of amps with my speakers. Bananas get compressed, bent, and broken on a semi regular basis. Admittedly, I'm an experimenter these days and for most people, they just plug it in occasionally.

I like'm bare and naked with neither spades or bananas. Cheapest winner of both

@hilde45  Bananas are not actually meant for gorillas.  🤣

So what do you use instead??
