Harmony is a new stereo interconnect cable from Black Rhodium hand built at the Black Rhodium factory in Derby employing advanced design techniques developed by Black Rhodium for use in its most expensive products. Black_rhodium_harmony_interconnect

The wires in Harmony are insulated in silicone rubber “because its low dielectric loss ensures extremely low distortion due to dielectric absorption effects in which sound energy is absorbed in the insulation and released at a later interval of time to create highly audible time-smearing distortion”.

“‘Transient Phase Distortion’ is reduced by using thicker insulation than is usual in speaker cables, increasing the distance between conductors and thereby reducing the magnetic field seen in each conductor wire as a result of the magnetic field created by the current in the other conductor wire. A further increase in the distance between conductors is achieved by use of the attractive cable braid and this further reduces ‘Proximity Effect’ distortion.”

Construction of Harmony includes the use of two separate and complementary materials that damp mechanical vibrations within the cable without the expense of vibration stabilisers says the company’s press release.

Harmony uses RFI suppression technology originally developed for high end cables in its construction. This protects the signal wires from picking up radio frequency interference (RFI) generated from Radio, Wi-Fi, Mobile Phones and even central heating systems. Further Harmony is covered in a tightly braided screen to protect the inner cores from picking up radio frequency interference.

Harmony RCA cables are terminated with ‘Hourglass Silhouette’ RCA connectors, plated in gold for long life reliability. The shape of the connector bodies enables easy insertion and removal at the back of equipment.
