The ETI Research (formerly Eichmann) Bullet Plug RCA connector is a breakthrough in RCA plug technology, and the closest approach to no plug at all.Why the Bullet Plug connector is better than the RCA plug you presently use. The Bullet Plug connector is a totally new approach to RCA/phono connection where every aspect of electron flow has been considered.The result is an RCA compatible connector that can improve the performance of any analogue, digital or video cable - often dramatically.Please note the Bullet Plug is minimalist in design and appearance.If you’re looking for connector jewelry the Bullet Plug may not be for you. However if your objective is ultimate performance quality read on…What you should know about RCA plugs:The cables you now use are made from high-conductive, annealed copper or silver wires - terminated with low-conductive, gold-plated brass RCA plugs.Annealed copper has a conductivity rating of at least 100% IACS (International Annealed Copper Standard). Brass has a conductivity rating of 28% IACS.Because of this low conductivity, we believe brass RCA plugs act as a bottleneck to electron flow. Brass plugs may also cause phase errors and smearing through mass and skin effect.Another problem is the return/ground collar - which can impair electron flow through:Eddy current distortion - as electrons proceed to and from the RCA socket into the collar through multiple contact points.Capacitive distortion - where gaps exist between the socket and collar.Micro-arcing distortion - an electrical short that can occur where gaps exist between the socket and collar.Additionally, RCA plugs are coaxial designs (metal return/ground surrounding signal pin) that have an impedance effect. This impedance can have a varied and adverse impact on performance.The solution: The new Bullet Plug RCA connector solves the problems of standard and audiophile grade RCA plugs by providing a faster, cleaner signal of high purity and detail.To achieve this we have designed the Bullet Plug as a miniature cable - with high-conductive, gold-plated tellurium copper (CuTe) pins providing a rapid transfer of electrons to/from RCA sockets.In our patent-pending design, the return pin of the Bullet RCA Plug makes single point contact with the side wall of an RCA socket - concentrating electrons to one point thereby reducing distortion. This is a similar approach to “star earthing” used in amplifiers.

ANTICABLE Level 1 RCA Interconnect 0.5m, excellent condition. Lots of reviews and info from Anticables as follows; A stereo pair of ANTICABLES Interconnects which will enable line level analog connections between components. Highlights: A good choice for Vintage gear and systems on a tighter budgetOxygen Free CopperCopper impurities have been reduced down to 5 parts per millionMade in USA (one pair at a time in Lake Elmo MN)Design Concept: Typical interconnect cables usually have a signal wire surrounded with a thick plastic dielectric material, which is then surrounded by the ground conductor to shield it from EMI/RFI noise, and then more plastic dielectric material. This typical approach has the usual drawbacks of accumulating a lot of dielectric effect distortion, and an accumulation of shunting capacitance. The ANTICABLES Analog Interconnects use a different approach. Since air is a near perfect dielectric, no extra insulation dielectric material (beyond the thin red coating) is used, and the wires are suspended in free air. Eliminating dielectric effect distortion is what allows these interconnects to sound like music, (not a cable).
