I went to solder the high frequency leads directly to the low frequency binding posts last night and found the wires are terminated with a female flat spade connector which slides onto the male spade tab that is clamped/nutted to each binding post. I'm not inclined to cut and solder the leads on.
High Fidelity jumpers are out of my price range but thank you for the recommendation. I actually stopped into their shop in TX last March to look at some used speakers they were selling. They have some nice equipment and are very nice people.
As Mitch2 suggested, I have already tested the speaker cables connected to the low frequency posts versus the high frequency posts. It sounds better connected to the low frequency posts. I haven't tried positive to low and negative to high and vice versa and will give that a shot.
My goals were twofold with my original post.
1. upgrade the jumpers
2. obtain jumpers with spade on one end and banana on the other.
It sounds like I just need to find four decent banana plugs and replace one spade end with a banana on my current jumpers.
