The ETI-Research Link RCA Connector is purpose-designed to incorporate cutting-edge, premium-grade audio technology at a mass market price.
Since the return pin features a very low-mass design, to make it from ordinary Hardened Copper would not give the strength or durability required for soldering and everyday use. Therefore, the Link RCA Connector is made from Tellurium Copper, which maintains the connection strength needed to last for years and years without breakage or degradation of audio quality.
The housing of the unit is now made from aluminium. When we first started making the original Bullet we did not have to worry about all the electromagnetic radiation that is now floating around our audio systems. But today, with all the processors and switching power supplies commonly used throughout the industry, our audio systems are in a bath of noise.
This shift in industry adoption of contributors to EMI necessitated the change to Aluminium because it has very good EMI/RF noise rejection so as to keep your signal as clean as it possibly can be.
The LINK RCA Connector now has twin strain relief screws to keep your cable and the connection away from all the plugging and pulling stress many of these connectors are exposed to.
