Banana Plugs too narrow

Simply slipping in and out of the hole makes for a very unsatisfying listening experience.
Exactly how many owners have passed them around?
Anyway, yes, you can snip off the bananas and use bare wire.
But don’t just jam them in your speakers hole.
Take your time. Slowly twist the binding posts, gently at first, then faster and with more force as they start to loosen up. Then when you think they’ve reached the point where they are on the edge of coming off, slip your bare wire behind them, gently twisting them the opposite way until they are so tight you can’t do it anymore. Now, turn on your stereo. Or smoke a cigarette....

Here is a suggestion on what you can do if you have a leftover banana. :-)

Out of curiosity, what speaker cable are you using?  If I were truly smitten with the cable I'd inquire into sending them back to the manufacturer and have them replace the bananas with spade connectors.  A few years ago I did this with a pair of Kimber cables.  I think it cost me about $60 shipped working with Kimber. 

Wouldn't risk going bare, even if you are pretty sure where that speaker has been, it could have had a spade on the side. And.. wait, is this a 3-way we're talking about? Or ... five???

When I’m plugging into my speaker, I prefer the D’appolito position.
Too much? ok.
