The ETI-Research Nexus RCA Connector is a new direction for ETI. While they are the originators of the minimum mass star grounding philosophy, they believe that they can make a more conventional RCA Connectors that can offer many of the same attributes as the Bullet Plug.
In theory, an RCA Connector should allow the signal to transmit with little interference or effect. However, so many RCA Connectors are made from poor conductive metals such as brass which can alter the signal giving a brittle and harsh sound. The Nexus RCA Connector changes that with the use of 1100 series Copper for the Signal Pin Copper which has an IAC Rating of 102%. To ensure the durability needed for plugging in and out, the body is made from Tellurium Copper. This makes sure that the integrity of the plug is maintained for many years. The Nexus RCA has been changed to allow the signal wire and the return wires to be screwed in, so soldering is not required. However, if that is the preferred method you can still solder your interconnects cables.
