Review on 🔌 High-Quality 4MM Banana Plug Socket Connector Binding Post with Pure Copper Audiophile Speaker Binding for Amplifier Terminal + Audio Video Cable Plugs & Adapter - 2 Pairs by John Wei

These are incredibly high quality connectors, they have very low electrical resistance and actually look even better than the photos; on amazon they are shown with a domed cap but they actually come with polished round caps. The only complaint I have with them is that they don't even come close to attaching an 8AWG wire with a set screw on the end, and they don't pick up solder very well.
