IsoTek 24ct Gold Audiophile-Grade Power Connectors

The IsoTek 24ct Gold Audiophile-Grade Connectors are high-quality AC power connectors designed for custom power cables, cable upgrades and re-termination of existing audiophile power cords. IsoTek constructs every electrical contact surface from pure copper and plates it in 24-carat gold, combining high conductivity with resistance to tarnishing and corrosion. IsoTek

Available in multiple AC and IEC configurations—including US 3-Pin, EU Schuko, UK 3-Pin, IEC C7, C15 and high-current C19—the range accommodates cables from 4mm to 16mm in overall diameter and conductors as large as 6 AWG / 4.1mm. IsoTek

Pure Copper Contacts with 24ct Gold Plating

The electrical contact surfaces are manufactured from pure copper rather than conventional low-cost connector materials, then plated with 24ct gold. IsoTek

This construction gives IsoTek two important characteristics for an AC power connection: a highly conductive copper base material and a gold-plated contact surface that is substantially less susceptible to oxidation and tarnishing.

IsoTek uses 24ct gold-plated audiophile connectors extensively across its own EVO3 power-cable range, including Premier, Sequel, Elite, Optimum and Syncro. IsoTek

Designed for High-End Power Cables

These aren't signal-cable connectors or speaker terminals. They are specifically designed for AC mains power cables.

The connectors can be used when constructing a new high-performance power cable or when replacing the terminations on an existing cable. IsoTek specifically promotes them as an upgrade for existing power cords. IsoTek

That makes them relevant for power cables serving components such as:

• Power amplifiers and integrated amplifiers
• Preamplifiers
• DACs and digital sources
• Music servers and streamers
• CD/SACD players
• AV processors and home-theater electronics
• Power conditioners and distribution products

Up to 6 AWG Conductors

IsoTek designed the connector body to accommodate unusually substantial audiophile power cables.

Maximum cable diameter: 16mm
Minimum cable diameter: 4mm
Maximum conductor size: 6 AWG / 4.1mm. IsoTek

That broad range is particularly valuable when terminating large-gauge power cables because many conventional AC connectors physically cannot accommodate the diameter of the cable jacket or individual conductors.

4mm–16mm Cable Compatibility

The ability to accommodate 4mm through 16mm overall cable diameters also means the same connector family can be used across very different cable constructions. IsoTek

A source-component cable may use a relatively compact conductor and jacket structure, while a high-current power-amplifier cable can be substantially larger. IsoTek's detachable housing is designed to accommodate both.

Polycarbonate & Nylon Construction

The connector's mechanical construction consists of a fully detachable injection-molded polycarbonate main body with an injection-molded nylon front assembly. IsoTek

This modular design provides access to the internal termination points during cable construction while creating a durable outer housing once assembly is complete.

Multiple Connector Configurations

IsoTek offers the 24ct Gold connector platform in a broad range of mains and equipment-side configurations:

IsoTek's current product page explicitly lists C7, C15, C19, UK 3-pin, EU Schuko, US 3-pin, Australian and Swiss configurations. IsoTek

For The Grid's U.S. customers, the most relevant variants will generally be the US 3-Pin mains plug paired with the appropriate IEC equipment connector.

IEC C15 for Audio Components

The C15 configuration is the equipment-side connector used for many conventional high-end audio components.

IsoTek itself describes C15 as its standard option for most equipment. IsoTek

This is likely to be the highest-volume configuration for customers building or re-terminating power cables for source components, preamplifiers, integrated amplifiers and other conventional audio electronics.

IEC C19 for High-Current Components

The C19 connector uses the horizontal-pin high-current IEC configuration and is intended for equipment fitted with the corresponding C20 inlet.

IsoTek specifically identifies C19 as the high-current option within the connector range. IsoTek

C19 should not be treated simply as a larger C15. The equipment inlet determines which connector is required, so customers should verify their component before ordering.

IEC C7 Figure-8 Connector

The C7 version provides a high-quality termination option for equipment using the familiar two-pole figure-8 power inlet.

This is especially useful because many compact audio and AV products use C7 power connections even when the remainder of the system uses larger IEC connectors.

Rather than requiring an entirely different cable philosophy for those components, IsoTek offers a matching 24ct-gold-plated connector within the same family. IsoTek

Used Throughout IsoTek's EVO3 Cable Range

These connectors aren't an isolated accessory in IsoTek's catalog. The company's 24ct gold-plated terminations are integral to several established IsoTek power cables.

For example, IsoTek specifies 24ct gold-plated audiophile-grade connectors on the EVO3 Premier, Sequel, Elite, Optimum and Syncro power cables. IsoTek

That makes the standalone connectors particularly useful for customers who want to maintain IsoTek-style termination quality when constructing, modifying or repairing a power cable.

One Shopify Product With Connector Variants

For The Grid, I would not create separate product pages for C7, C15, C19 and US 3-Pin. They are variations of the same IsoTek connector platform, and splitting them would create several thin pages competing for almost identical searches.

Use one product:

IsoTek 24ct Gold Audiophile-Grade Power Connectors

Then configure Shopify variants such as:

US 3-Pin
IEC C7
IEC C15
IEC C19
EU Schuko
UK 3-Pin
Australian
Swiss

That creates a stronger single SEO page while allowing Google Shopping and Shopify to recognize the individual purchasable variants.

Your current Grid listing is already being surfaced in product search under essentially this product name, so I would strengthen the existing page rather than create a new URL. IsoTek 24 Carat Gold Audiophile Grade Connector
