Spades vs. Banana plugs ??

Yes there are problems with both.Most of the time it depends on how much space you have between the sockets or screws.But I do use banana plugs when possible. 

Depends on your equipment and configuration….I use both to my advantage! 

I have never had the loosening issue with spades that is being reported here, and I do check them from time to time.  

@carlsbad2 - When I use banana connectors, my strong preference is for a minimalist BFA style banana plug - these first, and then these or these.

Pro Tip: Turn your equipment off when you are changing connections. You might save a trip to the repair shop.

@mitch2 Great summary of choices with BFA.  KLEI is always great.  But I prefer the simple one that you linked last.  Crimpable and solderable.  low mass.  Simple and effective.  Not that the others aren't great.
