Spades Verses Bananas?

Banana with self locking. I do like cardas connectors and copper binding posts. Amazon does  have some self locking bananas and you can stack them piggyback for multiple wire. They are screw contact for wire and some fit my 4 gauge wire. I have had spades come lose and be too small of opening and have to spread them open with needle nose to fit some amps. Good luck experimenting.enjoy the music.

Great stuff and good conversation.  I do not notice a difference in sound quality, but I love my cables that offer both options depending on the speakers.  Focal's and B/W's seem to like spades, JBL's work better with bananas  

Had a long talk years ago with a high end dealer in NYC. He said that ironically they both sound the same, and for a home system, where the cables are not constantly being switched, there was no downside to bananas. But that for dealers, for whom bananas were an important convenience, that the bananas would degrade...I have found this to be true in my systems...

I never compared same brand/composition/quality spades vs bananas 🍌 

I did compare copper, rhodium, gold plated and prefer gold plated connectors. Lately rhodium doesn’t agree with my ears…don’t know why…just annoys me and sounds off. 
My speakers and my amp made the decision easy - neither the speakers nor the amp accept bananas
