STEREOKRAFT

Below you can find information about the components used in the construction of this product.

• The ultimate Keith Louis Harmony RCA Plug design
• Proprietary mathematical modeling is utilised to produce the Silver Harmony’s ground to signal pin relationship, parameters, and determines the proprietary metallurgical processes that are used. Extrapolated: >101% IACS, even >103% IACS 
• Excellent for digital. 100% compatible with SPDIF standards
• Glass filled heat resistant thermoplastic polymer body and collar
• Tolerates high temperature soldering required for high silver content solder
• Single point grounding
• Cable OD sizes from 4mm to 9.5mm. Small cable grommet and 2 screws supplied to retain and secure the cable
• Higher conductivity. Calculations indicate a progression in IACS percentage, in the series. Greater than that of Classic or Copper RCA plugs.
• Recommendations: depending on the audio system...: Burn-in Time: >175hrs and even >275hrs

• MATERIALS: From the very outset, KL has had an understanding of and a sensitivity to electron/energy flow. His designs focus on signal integrity, the elimination or mitigation of causes of electron turbulence, most notably eddy currents, capacitive reactance, and micro- arcing. A central theme in his designs has been his choice of materials
• OPTIMUM MASS: Bigger, thicker, and more massive doesn’t add up to better sound. In fact, quite to the contrary. A studied, optimised, and in most cases a minimalist approach to mass actually results in better sound – and better electron/energy flow. KL’s proprietary signal to ground mathematical formulae, ensure an optimal architectural relationship between all metal complements and dielectrics that have been utilised. The result is control, and the avoidance of sonic compromises caused by skin effect. Also, the reduction of EF and EMF interference. Controlling these parameters ensures a complete, full, and extended frequency range, where harmonics are conveyed from component to component intact.
• METALLURGY: This is of paramount importance; and something that’s been central to KL’s designs from the very beginning. KL is committed to implementing and using, in his current Harmony RCA plug designs, only conductors that are more conductive than pure copper, and even pure silver.
  KL is in fact responsible for bringing IACS (International Annealed Copper Standard) into the audio conversation. Using pure copper (100% IACS) as a reference, the IACS percentage defines a metal’s electrical conductivity relative to pure copper. For example, brass (25%~37% IACS), bronze (15 ~ 48% IACS), and rhodium (35%~38% IACS) are poor to average electrical conductors when compared to pure copper. Pure silver is better at 105% IACS. Gold is about 70% IACS. These numbers — 100, 28, 105 and 70 are known as percentages of IACS.
  KL’s Harmony RCA plugs are all at an IACS rating of 101% or greater, and are breaking the conceptual boundaries that have been previously thought to be absolute. A lot has happened since the days of the original Bullet Plug; and the metallurgy utilised in the Harmony RCA plugs represents new understandings that have grown out of research into the processes of forming and finishing—also, metallurgical affinities and intrinsic crystalline structures.
  KL also rejects the use of passivation for preserving and protecting conducting metals – something touted by some connector manufacturers as being a feature. We are opposed to zinc, zinc oxide or these kinds of coatings, and simply will not knowingly compromise our IACS ratings for unnecessary protection.
  It is important to note that the Harmony RCA plugs’ signal and ground pins are harmoniously formed in a way that the metallurgical processes work together and not in opposition to each other – both electrically and mechanically.
  Extrapolation indicates, electrically, that the utilised metal complements are at least as conductive as pure copper (100% IACS) and/or pure silver (105% IACS). In pure annealed form, pure copper and pure silver are too soft to machine and easily bend. As such, the machinable forms of copper and silver, as used in audio applications, have noticeably lower IACS values than their pure copper and pure silver forms. The bottom line is that conductivity (IACS percentage) is defined by a metal’s formation, i.e. its completed form. No matter how you get there and to quote Keith Louis, the proof’s in the pudding/listening. The Harmony RCA plugs excel in this area, and better any RCA connectors we have seen to date.
• ARCHITECTURE: Conventional RCAs utilise a metal collar, which encircles the signal pin as the plug’s ground – a configuration which contributes to the kinds of electron turbulence discussed earlier. These disturbances are in the form of electrical eddy currents, capacitive reactance, and micro-arcing.
  To combat the degrading effects of electron chaos, KL went way outside the box. He opted for single point grounding, sometimes referred to as star grounding in high-end electronics, where the plug makes single point contact with the female RCA socket. In so doing, he eliminates the metal collar. This is a radical departure from eighty years of RCA connector design, and eliminates every vestige of eddy current turbulence, capacitive reactance, and micro-arcing.
  When comparing the Harmony RCA plug to the Bullet plug, it is important to note that the Harmony RCA plugs signal and ground pins have been further and dramatically optimised in terms of shape, mass, thickness, and metallurgy – and are electrically and mechanically superior.
• MATHEMATICAL MODELING: The relationships between ground and signal pin, i.e. metal complement, mass, and other critical parameters, are derived via KL’s signal to ground mathematical formulae, and differs from Harmony RCA plug to Harmony RCA plug.
• SUMMARY: Each Harmony RCA plug in the product range, from Classic to Perfect Harmony RCA plug, offers progressively enhanced conductivity from >101% to even >105% IACS, which results in an improved response to those exceptionally fast transient signals in the audio signal, improvement in the transmission and resolution of fine details, and achieves a more realistic reconstruction and presentation of the recorded image.
