KLEI Copper Harmony Phono/RCA Plugs (4 Pieces)

The Harmony®Plug is a new revolutionary approach to Keith Louis Eichmann’s (aka KL) previous Bullet Plug design, which itself was a revolutionary approach to Phono/RCA connection. It represents a wholesale rethinking of something as basic as the venerable Phono/RCA plug; a connector designed over Sixty years ago by The Radio Corporation of America (RCA).

KL’s objectives to improving the humble RCA plug are… improved conductivity, enhanced signal integrity, higher resolution, and improved connection. These objectives are important and significant in critical areas of Electron Flow and Signal Integrity for High Resolution audio performance and requires close attention to all areas of Connector design, as follows…

Geometry/Materials/Mass – KL’s Signal/Ground formula/architecture, ensures Optimum mass of Metals and Dielectrics are used to avoid skin effect, maintain structural Strength and Reliability, and minimise Reactive, EF, & EMF effects. Controlling these effects ensures that a complete, full, and extended Signal frequency range, and their harmonics, are transmitted from Component to Component, which further ensures that the listener enjoys a complete, full, extended, detailed, involving, and musical presentation.

The following are the improvements that KL (Keith Louis Eichmann) has made to the KLEI™Copper Harmony plug design when compared to his previous Eichmann Copper Bullet plug design…

• Proprietary mathematical modelling optimises mass, thickness, and composition of the conductive pins to enhance electron flow, incorporated in accordance with KL’s proprietary Copper Signal/Ground formula, where extrapolated results are even >102% IACS.
• Signal/Ground pins are now much stronger and shaped like a tag, which makes soldering small/large/multiple wires, very easy.
• Signal/Ground Anti-Short shield has been added between the Signal/Ground solder tags.
• Signal/Ground pins are arranged to maintain a maximised distance from each other, and the utilised foil technology ensures that capacitive, inductive, and EMF effects are minimized.
• Head assembly jaw structure has been redesigned, and mechanically improved, to allow an easy snap-like connection to an RCA socket, ensuring the ultimate connection with easy removal.
• Ground pin includes thread teeth to ensure that if a conductive housing is utilised, ie of metal or carbon fibre, it is star-point grounded.
• Housing assembly uses 2 screws to retain and secure the cable.
• Extremely high temperature melting point thermoplastic polymer has been utilized.
• Recommendations: >150hrs Burn-in, Cable OD sizes from 4mm to 9.5mm.
