IT’S 60 YEARS since the original RCA/Phono plug was designed by RCA. Now, hot on the heels of the entry-level Copper Harmony RCA plugs from KLE Innovations (HFC 388), come the Silver Harmony and Pure Harmony RCA plugs. The Eichmann Bullet RCA plug has gained a well-deserved reputation as a high-quality RCA/Phono plug. One of its features is that, along with the likes of WBT, it has a single-point earth return contact. However, since the success of the Bullet, Keith Louis, the man behind the Eichmann Bullet, has launched KLE Innovations in Australia to produce a brand new range of products, including the Harmony RCA Plug. The range is the result of a project aimed at developing the design of the Bullet in order to improve conductivity and signal integrity across the connection.
Enough talk and so much for the theory, the proof of the pudding is how they sound. After running them in, I find that in comparison with the Copper Harmony’s, the Silvers offer similarly excellent imaging, but seem to offer improved clarity and transparency to the sound.
The Pure Harmony’s appear to take this improvement a stage further by opening up the sound stage. Bass drums also have better attack.
In my opinion, the Silver and Pure Harmony plugs are superb value for money, work extremely well and so come highly recommended… Neville Roberts, Hi-Fi Choice 🙂

The KLEI Silver Harmony plug, when used with high performance interconnect cable, conveys an incredibly detailed analogue signal that results in a very realistic three dimensional reproduction of recorded music, regardless of whether it originates from an Analogue or Digital source… Steve Reeve 🙂
