KLE Innovations is founded by Keith Louis Eichmann (aka
KL) and Patricia Eichmann with the goal to develop products
which deliver the highest quality and that all enjoy
the ultimate experience from their audio (visual) system.
KL's reputation as true innovator in high performance
audio (visual) connectors, cables, and resonance device
technologies is legendary. Importantly, the wonderful
plaudits and reviews that KL's inventions/designs have
earned give them the drive and motivation to continue
to deliver industry leading products.
KLE innovations Harmony plug
first evaluation of the Phono/RCA plug pointed to obvious
metallurgical shortcomings. Most connectors, even those
marketed as “deluxe” upmarket Phono/RCA
plugs, are made from nickel and gold plated brass or
phosphor bronze with a conductivity rating typically
less than 28% IACS (International Annealed Copper Standard).
As a comparison, the high purity copper used in the
vast majority of interconnect cables has a conductivity
rating of 100% IACS.
Nickel is added solely to provide the jewel like appearance
that makes expensive connectors look expensive. While
achieving the desired appearance, it comes at a cost,
which is degraded sound or poorer picture quality, as
electrons flow through three dissimilar metals with
differing electrical and conductive properties.
Because of this low conductivity and the use of three
disparate metals, it is KL’s contention that standard
Phono/RCA plugs, even very expensive Phono/RCA plugs
marketed as “High-End”, compromise electron
flow and diminish the performance of the components
The conductive surfaces of the Harmony®Plug in contrast
are formed from a dense proprietary high purity silver
plating (>106% IACS). The contacts are made from
99.999% pure copper (having over 101% IACS) or from
pure silver (having over >106% IACS) to ensure maximum
conductivity. This provides >320% greater conductivity
than the gold plated brass connectors used in the vast
majority of deluxe Phono/RCA plugs.
Proven metallurgical choices result in better signal
transfer and electron flow that is consistent with the
highest quality interconnect cables.
Using a direct dense proprietary high purity hard silver
plating on the conducting surfaces of the pure copper
Harmony®Plug pins allows the elimination of the
nickel/gold plating typically used as the third metals
in a confusing composite on standard Phono/RCA plugs.
The dense proprietary high purity hard silver plating
produces the performance and sound characteristics of
4-nines pure silver and no additional plating is required
to preserve signal quality.
While the metallurgical understandings are significant,
the second observation regarding the Phono/RCA plug
turned out to be ground breaking. It related to a problem,
overlooked for decades, that is intrinsic to the Phono/RCA
plug’s design and something as fundamental as
the architecture of the RCA Socket itself.
That is the Phono/RCA ground collar which acts as a
conductor that transfers electrons from multiple directions
between the centre pin and its surface, are prone to
electron turbulence called eddy currents. These turbulences
are nothing less than electron chaos, exacerbated by
the nonspecific point of ground in the Phono/RCA plug’s
design, as an entire surface encircling the centre pin
forms the electrical ground. Capacitive reactance and
micro-arcing are additional artifacts of this architecture.
The Harmony®Plug addresses these issues and offers
an elegant and arguably major solution to the Phono/RCA
plug that is so fundamental and so extensive that we
have been granted a patent. The solution being, rather
than encircle the centre conductor pin with a formed
metal collar as ground, KL opted for a single point
ground contact similar to star earthing/ground in high-end
electronics. KL’s Harmony design features a redesigned
single point ground connection, which has an optimised
shape, mass and thickness of the conductive elements,
eliminates every vestige of eddy current turbulence,
capacitive reactance, and micro-arcing.
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
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.
