Spade on spade or banana and spade?


I have a question which I've thought about but can't come to a conclusion. My speakers can be biwired but I've decided to use a single wire with a 20" jumper. The speaker cable and the jumper will have to go into the same connector. I can use spades or bananas and I want to use the best combination for a secure connection. Would it be best to use all spade connectors or to go with a banana connector on one end of the jumper? Or another way to say it would be: is it better to put two spades in a connector or to use a spade and a banana?

Another possibility. Take a peak behind your binding posts to see how they are connected. You might be able to double-up on one binding post there. I have found that any connector will degrade the sound. I'll also read the same wire should be used for your jumpers as the spk. wire you are using. I will say that in my experience using diffent jumper wires will affect the sound. Reread your question. I personally would use a spade both top and bottom.
Optimally, I would use one spade and one locking banana. My experience with doubling up on spades has been that its harder to maintain as tight a connection as you get with just one. Initially it seems OK but they can work loose easier. YMMV.
