Spades vs. Banana plugs ??

Good quality spades for best sound. 
 

Bananas for convenience but poor sound. 
 

The tight screw down compression of a spade is always better than loose banana slip in connection. 
 

Just don’t be a dummy and let the spades short/touch.

I’ve done many years of DIY using high end cables and connectors and had spades and bananas. Left bananas connectors long ago due to poorer sound quality.

Bananas, particularly the ones that spin are, for sound quality, not great and the connection degrades faster over time due to the low compression slip in fit.

Perfectly fine for mid fi audio tho where uncompromised SQ is not a goal
