KLEI Harmony Phono/RCA Plugs

 

A New Revolution By KL (Keith Louis Eichmann)

The KLEI™Harmony Phono/RCA Plug is a new revolutionary approach to KL’s (Keith Louis Eichmann) 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 Charge 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.
  • Metallurgy – we/KLEI do not waste the effort gained in the other aspects of our designs by compromising with metals less conductive than Copper or Silver.
  • Metal Conductivity %IACS (IACS – International Annealed Copper Standard)
    • Silver – >105%
    • Copper – >100%
    • Silver (Machinable) – 92.5% ~ 96%
    • Tellurium Copper (Machinable) – 90% ~ 95%
    • Gold – 65 ~ 75%
    • Aluminum – 60 ~ 65%
    • Bronze – 15 ~ 48%
    • Beryllium (low/high copper content) – 17% ~ 43%
    • Rhodium – 35% ~ 38%
    • Brass (low/high copper content) – 25% ~ 37%
    • Tungsten – 31%
    • Nickel – 24%
    • Palladium – 16%
    • Platinum – 16%
    • Tin – 15%

KLEI™Harmony Phono/RCA Plug Architecture

The conductive pins of the KLEI™Harmony Phono/RCA Plug are formed using our proprietary high conductivity alloys, the Copper alloy having an IACS Rating >101% and the Silver alloy having an IACS rating >106% to ensure the highest levels of conductivity. When compared to a typical gold plated brass connector used in the vast majority of deluxe Phono/RCA plugs, the KLEI™Harmony Phono/RCA Plug range, utilizing our proprietary alloys, achieve improvements in conductivity exceeding 320%. Proven metallurgical choices result in improved signal transfer, and electron flow, which is consistent with high resolution interconnect/digital cables.

KLEI’s proprietary high conductivity Copper/Silver alloys vs ‘Pure annealed Copper/Silver’…

    • Our Testing, and Reports we have received, are confirming…
      • Electrically, the proprietary high conductivity Copper/Silver alloy utilised in the KLEI™Harmony Phono/RCA Plugs is equivalent, and even superior, to ‘Pure Copper/Silver’.
        • Pure annealed Copper and Silver (>=99.9999% purity)… >=100% and >=105% IACS conductivity, respectively.
        • KLEI™Harmony Phono/RCA Plugs proprietary high conductivity Copper/Silver alloy… >101% and >106% IACS conductivity, respectively.
        • Our evaluation is that our KLEI™Harmony Phono/RCA Plugs proprietary high conductivity Copper/Silver Alloys are equivalent, and even superior, to ‘Pure annealed Copper/Silver’…
          • As such, we believe that our proprietary high conductivity Copper/Silver Alloys can be called PURE and equivalent to 99.9999% pure Copper/Silver!
          • Further, we shall now refer to our proprietary high conductivity Copper/Silver Alloys, asKLEI PureCopper™ or KLEI™PureCopper and KLEI PureSilver™ or KLEI™PureSilver.
      • Mechanically, the KLEI™Harmony Phono/RCA Plugs proprietary high conductivity Copper/Silver alloy is much stronger than ‘Pure annealed Copper/Silver’ and the KLEI™Harmony Phono/RCA Plugs proprietary high conductivity Silver Alloy is nearly as strong as the Copper/Brass alternatives.
      • Sonically, we believe that the KLEI™Harmony Phono/RCA Plugs proprietary high conductivity Copper/Silver alloy is superior to ‘Pure annealed Copper/Silver’, especially when designed in accordance with KL’s Signal/Ground formula, but the proof of the pudding is in the eating, or in this case in your listening, and your Feedback and Impressions are welcome.

Conventional RCA’s are designed with a Metal Collar, which is prone to electron turbulence called Eddy Currents. In addition to this Capacitive Reactance and Micro-Arcing are additional artifacts of the metal collar architecture.

    • To combat this KL opted for a Single Point Ground contact similar to Star Earthing/Grounding in high-end electronics which in turn eliminates every vestige of Eddy Current Turbulence, Capacitive Reactance, and Micro-Arcing.
    • Further, with the KLEI™Harmony Phono/RCA Plugs design, KL has redesigned the Single Point Ground pin with an optimised shape, mass, and thickness.

Our proprietary high purity silver plating (>106% IACS) is applied directly to the conducting surfaces of the KLEI™Harmony Phono/RCA Plugs pins, as required. This produces the performance/sound characteristics of 4-nines pure silver (>106% IACS) and no additional plating is required to preserve signal quality.

Summary

KL believes he has, with this new KLEI™Harmony Phono/RCA Plug blueprint, solved a series of problems that collectively degrade audio/video performance and that do so in an additive manner. The importance of this innovation and redesign cannot be overstated. Its ramifications extend to every Phono/RCA interface in which high quality signal transfer is an issue. Extensive listening and critical comparisons played a major role in the evolution of the design, confirming at every juncture the audibility of properly applied science in even the area of Phono/RCA connection.

In summary the KLEI™Harmony Phono/RCA Plug is a further innovation/revolution and totally new approach to Phono/RCA connection.
