Schmitt Custom Audio KLE Silver Plated Copper RCA interconnects are now being offered with a wide selections of wire and cable.
I choose the KLE Copper Harmony Silver Plated Pure Copper pin RCA for its outstanding cunductive measures reflecting sonically second to none.
KLE RCA's can ( in some cases ) be very tight and some will try to force them on. Heating up (hair dryer or the likes) the KLE RCA's just before installation makes them slide on much easier and once they cool down they seem to have a Memory and stay at the desired fit from then on .
Specs for the KLE Copper Harmany:
KLEInnovations(KLEI)… Copper®Harmony RCA Plugs
Signal/Ground pins utilize KLEI PureCopper™ with >101% IACS conductivity
An ultra high purity Silver plating is utilized to protect the pins from oxidization.
Signal/Ground pin optimization has been utilized to enhance electron flow,
and designed in accordance with KL’s Copper Signal/Ground formula.
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 low noise/distortion in a Warm Musical and Involving manner from a Black/Quiet Background.
Reports received, indicate the KLEI Copper®Harmony when compared to the Eichmann Silver Bullet RCA plugs, has noticeably better PRAT, Decay, Timbre and Texture, Edge Control and Extension, Resolution, and Stage.
The following are the improvements that Keith Louis Eichmann (aka KL) has made to the Copper®Harmony Phono/RCA plug design when compared to his previous Bullet®Plug design…
Signal/Ground pins utilize KLEI PureCopper™ with >101% IACS conductivity (not Tellurium Copper (92~95% IACS) or Brass (28% IACS).
Signal/Ground pin optimization to enhance electron flow, in accordance with KL’s Copper Signal/Ground formula.
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.
The Head Assembly jaw structure has been redesigned and mechanically improved, to allow an easy snap-like connection to a Phono/RCA socket, ensuring the ultimate connection with easy removal.
Ground pin includes thread teeth which ensures that a metal Housing is star-point grounded.
The 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.
Keith Louis Eichmann (aka KL), prior to 1998, had an obsession with electrons and an obsession for sonic purity, musicality, and a passion for high performance audio; the result was the Eichmann Bullet plug. KL continued to focus his attention at the atomic level with a commitment to not only preserving, but enhancing electron flow. The sonic results from the application of his theories were ground breaking. The revolutionary ideas represented a paradigm shift in cable and connector design, forever raising the benchmarks for sonic performance.
The KLEI Copper Harmony RCA Connecters using eutectic Silver Solder to the 4/9 22 gauge pure silver create a sound stage second to none.
