The original Bullet Plug was anything but a quiet revolution. It was an all-out assault on the precepts, the taken-for granted compromises inherent in the design of the RCA jack, and conventional thinking. After all, the RCA jack was a connector designed by the Radio Corporation of America (RCA) over 80 years ago for the connection of a 'record player' to their radios. Despite its humble beginnings, this connector became by default the industry standard for component connection, and remains so to this day. Accepted for what it is, the RCA jack offers industry-wide compatibility, but is far from an ideal connector.

After seventeen years, a patent, a trademark, and numerous copycats, the original Bullet Plug has undergone a significant redesign and improvement. That same outside-the-box thinking by Keith Louis Eichmann, which produced the original Eichmann Bullet Plugs, has been applied with many further and advanced improvements to produce the new generation Eichmann Harmony (Bullet) Plugs -- the mantle has been passed on. The Harmony Plugs, by KLE Innovations, deliver vastly superior performance and simply sound better.

METALLURGY. This is of paramount importance; and something that’s been central to Keith Eichmann’s designs from the very beginning. Keith is committed to implementing and using, in his current Harmony Plug designs, only conductors that are more conductive than pure copper, and even pure silver. 2 Keith 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.

It is important to note that the Harmony 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) 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 Eichmann, ‘the proof’s in the pudding.’ The Harmony Plugs excel in this area, and better any RCA connectors we have seen to date.

 

CLASSIC HARMONY (BULLET) PLUG

  • Glass filled heat resistant thermoplastic polymer body and collar
  • Tolerates high temperature soldering required for high silver content solder · Single point grounding
  • Excellent for digital. 100% compatible with SPDIF standards
  • Proprietary mathematical modeling is utilised to produce the Classic’s ground to signal pin relationship, parameters, and determines the proprietary metallurgical processes that are used. Extrapolated results: >101% IACS
  • 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 the Eichmann Copper and Silver Bullet plug
  • The KLEI™Classic Harmony plug pins incorporate highly conductive materials, such as pure copper and pure silver, where extrapolated results are even >101% IACS
  • Recommendations: >125hrs Burn-in, Cable OD sizes from 4mm to 9.5mm

 

COPPER HARMONY (BULLET) PLUG

  •  Glass filled heat resistant thermoplastic polymer body and collar
  •  Tolerates high temperature soldering required for high silver content solder
  •  Single point grounding
  •  Excellent for digital. 100% compatible with SPDIF standards
  •  Proprietary mathematical modeling is utilised to produce the Copper’s ground to signal pin relationship, parameters, and determines the proprietary metallurgical processes that are used. Extrapolated results: >101% IACS and even >102% IACS
  •  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 the Classic Harmony plug
  • Signal/Ground pins are pure Copper and >101% IACS (not Tellurium Copper (95% IACS) or Brass (28% IACS).
  • Recommendations: >150hrs Burn-in.

 

Steve Reeve, reviewer for Fine Art, has the following to say about the Copper Harmony (Bullet) Plug in his Fine Arts review: ‘I cannot recall my modestly priced hi-fi ever reproducing music with such clarity. Every instrument, every artist, every venue, every album, is being reproduced in a manner that would normally be attributed to spending thousands of dollars on significantly better components — not a $60 set of RCA plugs! Even my oldest recordings are revealing details I’ve never before heard. There is also a warmth that was previously missing, which is especially nice for digital playback, creating a more engaging rendition, with what appears to be a much larger “sweet spot” as a bonus.’

More from Steve Reeve, reviewer for Fine Art. From his review on the Pure Harmony (Bullet) Plug. ‘The one thing the KLEI Harmony Plug range is not… pretentious. There is no gold or rhodium plating, no carbon fibre casing, no cryo treatment. If you are after looks – select another product. But… If you want a serious product capable of the ultimate in RCA performance… KLEI Pure Harmony Phono/RCA Plug… pure genius, pure performance, pure magic!’

  • Recommendations: >200hrs Burn-in, Cable OD sizes from 4mm to 9.5mm.

 

Steve Reeve, has the following to say about the Absolute Harmony (Bullet) Plug in his Fine Arts review: ‘So, why would you use the KLEI Absolute Harmony RCA, as opposed to the Pure Harmony, or Silver Harmony or Copper Harmony? I use the KLEI Absolute Harmony RCA 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. So, there you have it!’
