It seems like no matter how tight I torque down binding posts, if I come back in a month at least one wire will be loose. I tin the ends of the wire too.
So, I'm wondering if the wire could be soldered into a banana plug and use that instead. Will gold plate solder? I know chrome won't.

The problem is one of elasticity verses malleability. Clamping pressure requires elasticity. If the material deforms, then it sort of "bleeds off" clamping pressure. So you're up against that. Copper isn't elastic at all - It's way down there with nickel and aluminum.
I like using bananna plugs or spade lugs. Bananna plugs have springs made of a material that is elastic plated with an electrically conductive metal that doesn't oxidize. That allows clamping pressure from the elastic base material. If a screw connector is desired, spade lugs will provide the same sort of thing - an elastic base metal plated with an electrically conductive surface metal. Tightening down on the spade lug provides clamping pressure without deformation.

If the banana plug uses pressure against the copper, isn't that the same situation? That's why I was wanting to solder the wire to the banana plug.

I tried soldering some gold plated banana jacks and plugs. This makes a great connection. The wire will break before the join does.
I had to revert to my soldering gun. The heat needs to be applied quickly, so that the plastic in a wall plate doesn't get too hot and lose its shape around the metal.

Hi, I use only banana plugs. I am always swapping things around and they are great for that. I also use IEC power connectors on all my gear that uses AC mains voltages.... even the turntables.
Good Listening
