Review on FosPower Speaker Connectors Receiver Amplifiers by Ricardo Thotti

This is a banana plug, not rocket science. I even used pliers to scratch the surface and it didn't move more than 90 degrees so it got stuck (yes I was going in the right direction}) I only needed 10 pairs for this receiver but it is a big disappointment but not worth returning and from a technical point of view I am very worried about short circuits since they are all metal without insulation. I just paid $1100 for my Denon avr-x4500r if I'm going to be pissed. I'm glad it uses 2 screws unlike many others who only use 1 screw but don't use a cable holder so they look unfinished. I wouldn't buy them again and I can remove them and just solder my connections. I need to connect 1 more amp, I will just solder the connectors on this one.
