Spades vs. Banana plugs ??

Actually a dab of Loctite, tightening with a wrench works great and Kimber does make an expandable spade.

Bananas are much safer 

I doubt many have actually gone to the trouble of “A/ B ing” the same wire in the same system w/ spades & bananas & I know I haven’t. My experience is that good quality bananas stay put & spades often don’t & require regular tightening. Also depending upon the amp connection, spades can necessitate a tight right angle turn of the cable which can be tough w/ thicker cable & probably the cause of the connection loosening. Unclear which method has more contact surface area. 

If you can hear the difference, you have better ears than I do! That said, I like neat and tidy. I use banana to the speakers and spades to the amp.
