Breakthrough claim in RCA plug technology

Australian inventor Keith Eichmann has developed what he believes is the most advanced RCA plug ever made.

Australian inventor Keith Eichmann has developed what he believes is the most advanced RCA plug ever made.

The Bullet Plug connector (subject to patent applications worldwide) is the first major improvement to the RCA plug in 50 years.

Listening tests carried out by Keith Eichmann reveal that many RCA plugs, including expensive audiophile varieties contribute colouration to the music signal.

According to Eichmann one reason may be the large mass of poor conductive metal used for the return or ground.

"While most interconnect cables are made from annealed copper with conductivity rating of 100% IACS (International Annealed Copper Standard), most RCA plugs are made from brass with conductivity rating of 28% IACS".

Eichmann also believes the return or ground collar of an RCA plug (designed to surround and make contact an RCA female socket) may cause "eddy" type distortion, as electrons enter the socket from a variety of directions.

These problems are addressed in the new Bullet Plug RCA connector.

The Bullet Plug connector is designed as a miniature cable - with high conductive gold-plated tellurium copper (TeCu) pins providing a rapid transfer of electrons to RCA sockets.

The signal pin is similar in design to that used in most RCA plugs.

The return pin of the Bullet Plug connector however is revolutionary.

It makes contact with the side wall of an RCA socket, in doing so concentrates electrons to one point thereby minimising eddy currents and distortion.

This is similar to "star earthing" in amplifiers.

"We replace the large mass of brass material normally used as the RCA plug return with a highly conductive, miniature return pin that reduces distortion and provides excellent signal transmission capabilities", said Eichmann.

The result when using the Bullet Plug connector is a speed and transparency of sound that is immediate and obvious.

Music is faster, cleaner and more detailed - like the sound of no plug at all.

And because the Bullet Plug connector is easily attached to most interconnect cables (9mm diameter and less), and is compatible with all RCA sockets, hi-fi and video enthusiasts can gain a big improvement in sound and picture quality for a small investment.

The Bullet Plug is now available in most countries around the world.
