Chord VEE 3 silver-plated RCA plug: The new plug surround takes design cues from the acrylic plug casing fitted to the Chord Sarum interconnects. The material used for the plug casing is ABS with a textured finish that makes the VEE 3 plugs easy to install and remove. The new shape ABS outer shell is combined with a new internal design featuring direct silver-plated signal contacts. The signal insulation block is PTFE and the unique Silver-plating process improves signal transfer across all frequencies. The signal return surround contact provides precise high-pressure contact with RCA sockets. The cable clamp combined with the cable design minimises changes to cable impedance that can have a negative effect on sound quality.
