Their new ChorAlloy plating loudspeaker plugs are designed to bring both the electrical and sonic benefits of silver to speaker cables everywhere.

The new plugs will be fitted to all Chord Company speaker cables, as well as being separately available as a retro-fit upgrade, enabling this revolutionary 4mm connector to improve other brands of cable, too.

For many years Chord have been using silver-plated copper conductors in their designs.

Their silver-plated designs are paired with silver-plated connectors.

Using silver in cables can be misunderstood, as many people still associate the use of silver with a bright, overbearing sound characteristic.

In Chord’s experience, however, this brightness is actually caused by a poor choice of insulation material rather than the silver!

The only major exception to this rule has been Chord Company gold-plated (4mm/spade) speaker connectors.

Why not gold?

Although gold is generally perceived to be the best plating material for high-quality connectors, its only major advantage is its total resistance to corrosion (not normally a domestic issue!).

In their experience, the customer also associates it with performance and quality due to gold’s high commercial value.

Matters are further complicated by the various other plating materials on offer in the hi-fi industry (e.g. rhodium, copper, brass and nickel) with each having wildly differing prices and claimed performance levels.

Science, statistics and misinformation as we see it!

Gold is, in fact, the third most conductive metal available. It is outperformed by both copper (+140% better) and silver (+148% better).

Better conductivity means lower resistance and therefore, less signal loss.

Less signal loss means increased performance – as expressed by Ohm’s law!

Hence the name of their new speaker plugs, ChordOhmic

Although pure copper is a good conductor, at room temperature it is susceptible to oxidisation and drastically drops in conductivity when oxidised.

Plating the copper can protect it from this process. Plating materials include tin (25% as good as gold), nickel (33% as good as gold) and rhodium (50% as good as gold).

Crucially, silver-plating not only makes sense from an electrical point of view, it gives an audibly superior result during listening tests, when compared with gold plated connectors.

What about tarnish?

It’s a common mistake to think that because silver oxidises it is a poor conductor.

The reality is that silver does not oxidise until it reaches 170 C.

It does, however, tarnish at room temperature, reacting with sulphur in the air.

Although tarnished silver is not the nicest thing to look at (on ornaments or cutlery), electrically, it is less troublesome.

Tarnish (normally silver sulphide) is a soft and malleable material and can be easily moved aside with very little force.

They ensure these forces are present in their speaker plugs and spade connectors.

There are limited points of actual contact, even under fairly high levels of force.

By simply moving a connector in and out of the socket, it is possible to effectively clean the contact points.

Ensure all equipment is switched off before doing this simple maintenance procedure.

Plugs will also benefit from a major clean, using a good contact cleaner or enhancer.

THE CHORD COMPANY BEGAN

The Chord Company was formed in 1984.

It all started over dinner one night in Salisbury, when a group of visiting Naim Audio USA retailers asked Naim Audio UK for a good-quality DIN-to-RCA interconnect.

At the table, was one Sally Gibb, then married to a Naim Audio executive, who made the (historic) suggestion that she make the cables and start a business.

With the blessing of Naim Audio, the journey to make cables for America began.

With USA referring to cables as ‘cords’, the name The Chord Company, with its obvious musical connotations, seemed perfect and it quickly stuck. Sally drew a logo, designed the packaging and started testing prototypes. Completely British design and construction, although difficult to source at the time, was paramount and days of searching eventually led to suppliers of sufficient quality.

Friends at Naim Audio provided expertise and advice, with many of them helping to build the cables.

The first prototype was named “Chrysalis Cable” and the Americans swiftly returned with an initial order of 250! Cables were built, tested, packed and taken along to the Post Office.  Invoices were typed on a typewriter! After two steady years,

The Chord Company got its first press review (by Malcolm Steward) and then the phone started to ring…
