KLE Absolute Harmony Phono / RCA Plug

The KLE Innovations (Keith-Louis Eichmann) Silver Harmony Phono / RCA plug has been redesigned from the original Bullet Plug to overcome metallurgical shortcomings in the original design. 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 the phono plug / RCA connector.

KL believes he has, with this new phono / RCA 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 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 Harmony RCA plug is a further innovation and totally new approach to RCA connection.

Keith Louis Eichmann's new bullet plug design family, Harmony.

The following are the improvements that have made to the Absolute Harmony Phono / RCA plug design when compared to his previous Bullet Plug design:

• Signal and Ground pins both utilise Absolute KLEI PureSilver Alloy with >106% IACS conductivity.
• An ultra high purity Silver plating is utilised to protect the pins from oxidization.
• Signal and ground pin optimisation to enhance electron flow, in accordance with KL’s Absolute Signal / Ground formula.
• Signal and ground pins are now much stronger and shaped like a tag, which makes soldering small / large or multiple wires very easy.
• Signal and ground Anti-Short shield has been added between the signal / ground solder tags.
• Signal and 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 minimised.
• The head assembly jaw structure has been redesigned and mechanically improved, to allow an easy snap-like connection to a phono / RCA / cinch socket, ensuring the ultimate connection with easy removal.
• The housing assembly uses two screws to retain and secure the cable.
• Extremely high temperature melting point thermoplastic polymer has been utilised.
• Recommendations: >200hrs burn-in, cable outer diameter sizes from 4mm to 9.5mm.

Comments and Reviews:

Sound: Exceptional resolution, tight non-bloated deep / detailed / resolving bass, extremely articulate presentation, conveys subtle nuances with amazing dexterity, stage is spacious and envelopes the listener, Allows the full emotion of the music to be experienced, superb dynamics and an excellent micro detail presentation, displays delicate upper mid and high frequency detail / resolution and harmonic texture with precision and emotion, delivers music with very very low noise / distortion in a warm musical and involving manner from an very very black / quiet background.

KL's testing and reports received, indicate the KLEI Absolute Harmony when compared to the KLEI Pure Harmony, has noticeably better PRAT, Decay, Timbre and Texture, Edge Control and Extension, Resolution, and Stage. The following quotes are from the many reports that KL has received…

With the KLEI Absolute Harmony RCA plugs, right from the first track it was like a flashback to that first brief audition but something was now quite different…

• I didn't consciously discern the improvements in terms of the various metrics associated with performance evaluation, i.e. imaging, dynamics, details etc…, but, my level of enjoyment of the music had increased significantly.
• The music just seemed more complete, with more vim & vigour. It was crisp, clean and bold and my foot seemed as though it was tapping with a mind of its own. Every now and again the goose-bumps kicked in – it was a very interesting and pleasing experience.
• The gentle strumming really demonstrated just how good the KLEI Absolute Harmony RCA was at conveying minute details, since you can actually hear the pick hitting the next string in a single strum.
• "Oh boy, what a…" – OK, so you must think I'm being incredibly anal here, after all, why would that particular facet stand out? – Well, after playing guitar for over 45 years that particular strumming sound is something my ears have become acutely accustomed too and when I hear it in a recording, it has a tendency to leap out at me. Alas, the KLEI Pure Harmony RCA plugs was not quite able to perform to this level of detail.
• Tracks had produced a very wide and deep image with the KLEI Pure Harmony RCA plugs, but the KLEI Absolute Harmony RCA plugs was able to extend the depth of that image and provide a little better focus on the various instruments within it.
• One other facet that stood out was the high frequency detail extension of the KLEI Absolute Harmony RCA plugs, which enabled it to convey the very fine whispery textures of Sting's voice.
• The KLEI Pure Harmony RCA Plugs are an exceptional and technically adept performer, that delivers fine details, dynamics, spatial imaging, and an extended bass performance, with amazing clarity and dexterity. Something many other RCA's can only aspire too.
• The KLEI Absolute Harmony RCA plugs however, transcends those standard metrics and delivers a performance which leaves you with a smile on your face, while tapping your feet and simply enjoying an incredibly rich musical performance.
• I use the KLEI Absolute Harmony RCA plugs because currently, I believe there is no other RCA plug capable of performing to the same level. However, as with everything in life, one’s budget can be a deciding factor, so the Harmony Range provides an RCA solution to fit several budgets. The Copper Harmony is an excellent performer and each successive model extends the abilities of its predecessor to provide a musical performance of the highest calibre.
• The most notable attribute is the extension in the bass, which is deeper with superb control and significant texture.
• The image (sound stage) is as precise as the KLEI Pure Harmony RCA plugs, from the perspective of performer/instrument placement, but is more extended in depth and width, with additional space around individuals and instruments.
• The extremely fine micro detail/resolution that brings that element of realism to a live performance is also further improved, where delicate venue and instrument acoustics now fill the voids between performers.
• Plucked instruments exhibited a crisper staccato effect due to an improved dynamic performance.
• Instruments whose sound occupy the higher registers, such as glockenspiels, triangles and percussion chimes, sounded more detailed/resolute and complete, because their delicate harmonics are now even more faithfully reproduced.
• The improved detailing/resolution also contributes to an extremely smooth presentation of a violins upper register and a much more realistic reconstruction of sibilance.
• The KLEI Absolute Harmony RCA plugs should provide the biggest "bang-for-the-buck" of any single piece of audio equipment you have ever purchased!
• The KLEI Absolute Harmony RCA plugs should provide a level of performance to your audio system, such as with Turntable leads/cables, that you believed was only possible by significant component upgrades.
