Ugh. The machining and manufacturing of these plugs are both great. The price is great. I am an industrial electrician. I term wire daily. I formerly worked at a Pro-Audio shop. My original intent was to solder these. That is doable, upon inspection. My soldering iron is at work so I used them as intended as screw terminals. They will let loose of the wire no matter how tight you torque the set screw.
I am using high quality 12awg wire, the wire is new oxygen free speaker wire, and 4 conductor since I am bi-wiring. I am also using higher end components. A Marantz PM-6005 and PSB Imagine B Speakers. The connectors are too long for most situations, the body doesn't include a strain relief (really?), and the set screw is nearly impossible to torque to a point the wire doesn't slip out. Filling the cup with solder will solve all problems except for length. They are still too long for most cabinets, racks, and setups. I gave up on these and going straight to the binding post. I tinned the wire ends and shrikwrapped everything to make it look nice.
