"Keith Louis Eichmann 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.

  • An ultra high purity Silver plating is utilised to protect the pins from oxidization.
  • Signal/Ground pins utilise an even higher spec KLEI PureSilver™ with >106% IACS conductivity.
  • Signal/Ground pin optimization has been utilised to enhance electron flow, and designed in accordance with KL’s Absolute Signal/Ground formula.
  • Our testing, and reports received, show that the KLEI Absolute®Harmony when compared to the KLEI Pure®Harmony is Simply… even Faster, even Quieter/Noiseless/Blacker Background, and more transparent, and has noticeably better PRAT, Decay, Timbre and Texture, Edge Control and Extension, Resolution, and Stage."
