The new LINK RCA Connector is based upon the original Bullet Plug RCA from ETI Research, but has been improved with new benefits.
The ETI Research LINK RCA has been upgraded to use an Aluminium housing, which is ideal when you are using a fully shielded cable to address EMI/RFI. Previously, the aluminum housing was an additional option.
The LINK RCA now also has two opposing strain relief screws to better aid in securing the connector body to the cable. This helps relieve stress on the electrical connection and protects the connection from stress from multiple connection & disconnection cycles.
Each package contains 2 pairs of LINK RCA Plugs (4 total plugs), or you may optionally order a single pair. Please specify what color code you want for the pair, in the 'special instructions' section of the online checkout.
For the standard LINK RCA: The hollow central signal pin is now made from pure, unalloyed copper (vs Tellurium Copper for the previous ETI Bulllet) for even better conductivity. Since the ground/return pin of the LINK RCA maintains it's low-mass design, using pure copper would not provide adequate strength or the durability needed for soldering and multiple insertion > removal cycles. The benefits of the low mass design are far more important to the sound quality than simply replacing with a solid copper pin. The ground/return conductor pin is therefore still constructed with tellurium copper, in order to maintain maximum strength. Both signal and ground/return pins are also gold-plated for excellent conductvity, and to keep the contacts corrosion-free. Also included in the new LINK design is a metal housing with TWO grub screws that better secure the connector's strain relief to the outer jacket of your RCA cable.
For the SILVER LINK RCA: The hollow central signal pin is still made from solid, pure, unalloyed silver (just like the Silver Bullet) for the absolute best conductivity. The ground/return conductor pin is also constructed with pure, solid silver. Also included in the new LINK design is a metal housing with TWO grub screws that better secure the connector's strain relief to the outer jacket of your RCA cable. The ETI Silver LINK RCA also imrpoves upon the original Bullet Plug RCA by extending the outer portion of the housing towards the tip of the RCA, essentially providing a shield for the RCA plug's entire internal wiring.
