Eidolic 4-pin XLR with Tellurium Copper pins


 

Eidolic 4-pin XLR

 

The 4-pin XLR has emerged as the standard for ergonomic, clean, and simple connectivity on balanced headphone amplifiers.  Until now, this connector has been a compromise for those seeking the best system to connect flagship headphones, their cables, and their gear.  Through significant investment in production techniques we are able to offer a 4-pin XLR with the best possible contact material and plating, for an appreciable boost in fidelity.  

 

The Eidolic difference.  Today’s studio-grade 4 pin XLR is made with brass alloy contact pins, for a conductivity rating of approximately 20-25% that of pure copper, and there has been no alternative, let alone an improvement to these limited offerings.  With a minor addition of roughly 0.5% tellurium to 99.5% copper, the resultant alloy’s conductivity only falls from 100 to 93% of the conductivity of pure copper, while being greatly more durable and machinable.  This new 4-pin XLR is the world’s first to feature gold-plated tellurium copper pins.  With the Eidolic 4 pin XLR in the signal chain, we have done our due diligence to ensure that this is the final piece of the puzzle.   

 

Why gold?  Gold is the most conductive plating metal that is also oxidation-resistant, offering some advantages over silver and rhodium.  Especially for plugs that are not being connected 10-20 times per day the way a 3.5mm mini plug might be, gold is the smartest choice - it is typically direct plated onto the copper for an uncolored sonic presentation, it is considerably more economical than rhodium, and wears nearly as well as rhodium (specifically, for less abrasive sockets such as XLR sockets, gold has excellent wear characteristics).  It is the perfect complement to the most conductive base metal - the tellurium copper that lies beneath the gold.  

 

The body, and other notable components.  The Eidolic 4-pin XLR features a clean, sleek exterior of media-blasted nickel plated over a tough die-cast zinc shell and a matching solid metal rear cap in place of the typical plastic-and-rubber boot cap.  Distinctive grooves on the barrel set this connector apart and provide a secure grip when handled.  A high-powered laser burns the Eidolic logo into the metal.  Inside, the Eidolic 4-pin XLR features a user-friendly assembly with the industry-standard collet piece which grips the cable tightly when the back cap is screwed on.  The Delrin engineering polymer used for the contact piece’s insulation is highly heat-resistant, and will not soften even at the hands of an amateur.  The imposing weight of Eidolic’s 4-pin XLR is commensurate with its quality and the audible improvement that accompanies any cable project featuring this connector.

 

From day 1, Eidolic connectors have been designed with transparency in mind - both in sound quality and in their code of ethics.  These connectors will always be sold with the exact materials and alloy types stated clearly - if there is ever a question, it is met with an unclouded answer.  Many connectors sold today are described as “pure copper” or a “copper alloy” when they are actually tellurium copper (a strong, machinable alloy that is within 5% of pure copper’s conductivity and is 99.5% copper) or brass (a “copper alloy” that is generally about 60% copper).  Sometimes the description gets more creative, mentioning “hybrid” compositions and alloys.  The only way to sell connectors without misleading the public is to call each metal what it is - brass, phosphor bronze, tellurium copper, or pure copper.  There are all sorts of plugs for sale around the world described as “OCC pin” or “pure silver connector” or “pure copper connector” that come back as brass every time - and their “rhodium plating” is nickel - a less conductive look-alike.  There are connectors for which a pure copper assembly is simply impossible, being too delicate and impossible to accurately machine with such a soft base metal.  While no factory would take on such a project, pure copper is what is claimed.  For Eidolic, the truth comes first.
