Looking for solid, non-steel speaker terminals that are affordable, consider those made from gold-plated brass or pure copper. These materials offer excellent conductivity and durability without the high cost of silver.  These will be for a Klipsch Chorus 2 but maybe looking for a Triad gold Center as well.

Once we started using tube connectors, we quit using everything else.

Here are some options from Cardas:

Not sure how you are defining affordable. While these Cardas binding posts are affordable compared to other brands I'm familiar with, all of them are more expensive than tube connectors.

While tube connectors work best with their own studs on the speaker cables, they can accept banana plugs. Considering performance, their low profile flush mounting, and cost, the only advantage I see 5 way binding posts having is the ability to accept spade lugs.

Try these and see if you can hear an improvement.  Copper to copper, no iron, no tin, no brass...
