Bananas rule, spades drool. End of discussion.

Purifi and Benchmark measured the different types of connectors and found the bananas the worst measuring. There was an article/interview about this when Purifi was releasing their first amp module. Benchmark also mentioned the same in some article they wrote. They like SpeakON the best.

Very subtle bot correct.

don’t blame the spade…it’s the coarse thread el cheapo “ 5 way binding post “…

I prefer spades more. Newer had a problem with Cardas spades. Tight, reliable connection. However bananas could be very weak. Ones I accidentally pulled the cable just a little bit and one of banana connectors got bent. When I tried to straighten it up it cracked and broke. 

Locking Bananas (WBT Type) give you the confidence in their connection.

2 allen head set screws secure the speaker wire to the fitting. The threaded rod expands the leaves of the split banana for secure connection, reverse to disconnect. Color coded is handy.
