Spades vs. Banana plugs ??

As a 20 something with my first rig all adcom gear including the GFA 555? 200 watt power amp. While setting it up for the first time I bare wired the amp not noticing one strand touching the other terminal and faster then you can say Jackie Robinson the amp was cooked. If I recall back then they did not have protective fuses.Lucky for me Adcom was in New Brunswick NJ at  the time and  just  a 30 min. drive so off I went dead  amp in hand. For a dozen donuts they fixed the amp and did some other updates while I watched.I am forever thankful to Adcom for the kindness they showed this kid.Once shocked I don't bare wire,lol. Humm good reminder I think I'll check my connections.

Bare wire....Tube connectors...bfa banana... get yourself a small butane torch and do some ultra high purity copper solder (careful not to set yourself on fire in pursuit of high fidelity)... Or go to an artist or jewelry maker and ask politely without looking like a Sheldon.

Word on the skreets is that lead solder could damage purity...screw up the electron, quark, boson flo, etc...

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.
