The banana plugs on these cables are terrible. I was plugging them in to my Audiophonics amp (MPA-S250NC), so far so good. Then I unplugged them and the "shell" of the banana plugs got stuck in the binding posts of the amp. I had to use tweesers to remove the small metallic parts from the amp and was scared that I would damage the amp.
Otherwise the cable itself is OK. Very thick but pretty flexible.
