Furutech GTX-D High End Performance US Duplex Receptacle - Gold

 

The Furutech GTX-D Gold is a two-outlet NEMA wall receptacle for US-wired mains systems, rated at 20A on a 125V supply. It takes US NEMA plugs, not UK ones, so it is for US electrical installations, US-specification power distributors and power boxes built to US wiring practice. Where an ordinary outlet uses phosphor bronze or brass contacts because they are springy, each blade receiver here is pure copper plated with 24k gold, pressed against the plug by its own non-magnetic stainless steel spring. The copper no longer has to act as the spring, so it can be chosen purely as a conductor, and the grip on your power cable's plug stays firm over time.

The contact tips are folded back and rounded instead of meeting the plug blade with a sharp edge, which gives a larger contact area and stops the plating on your plug blades being scored each time the plug goes in. The body is nylon and glass fibre loaded with nano-sized ceramic and carbon powders to soak up vibration, under a polycarbonate cover, and the whole outlet sits on a 2mm stainless steel brace plate for rigidity. The main metal parts go through Furutech's Alpha cryogenic and electromagnetic treatment. Furutech also make a rhodium-plated GTX-D Rhodium, identical apart from the contact plating.

We also list the Furutech GTX-D NCF(R), and the two are easy to confuse. The NCF(R) version adds Furutech's Nano Crystal² Formula damping material to both the body and the cover, and comes with rhodium-plated contacts only. The GTX-D on this page has no NCF: its body uses nylon, glass fibre, ceramic and carbon, and you can choose gold or rhodium plating. Size, current rating and the copper conductor and spring design are the same on both. As with any mains wiring, fitting should be left to a qualified electrician.

 

What Furutech say about the GTX-D

Furutech's GTX-D duplex receptacles use 24k gold or rhodium-plated Alpha pure copper conductors, a material most makers avoid because pure copper is too soft to act as its own spring. Furutech get round this with a two-way conductor that separates the copper electrode from a non-magnetic stainless steel contact spring, giving firm contact pressure that stays stable over the long term without damaging the plating on plug blades. The electrode tips are folded and rounded to increase contact area, and the screw-down pressure plates are curved for the same reason. Vibration is controlled by a nylon and glass fibre body loaded with nano-sized ceramic and carbon powders, a 2mm stainless steel mounting plate and a cover screw that ties the cover directly to that plate.

 

The Pure Transmission Mission

A very Furutech power product, manifesting a devotion to best performance in every element of AC and signal transfer Considering that what you actually hear is in a very real sense the direct product of the incoming AC then the final few feet are of prime importance for best performance.

Of course everyone would love to make pure-copper receptacles, but its malleability – lack of stiffness – makes pure copper a poor choice. That’s why you’ll find less conductive metals like beryllium copper, phosphor bronze or brass in some receptacles. Furutech’s intense engineering scrutiny has resulted in an industry-first, a technique allowing us to use special Furutech 24k gold- or rhodium-plated α (Alpha) pure copper conductors strengthened and sprung by our innovative nonmagnetic Stainless Steel Conductor Spring System that keeps a firm grip yet won’t damage male connector blades or their plated surfaces. Even the screw-down pressure plates are curved to maximize contact area. The GTX receptacle can be summed up in a word; virtuoso!

 

Industry-first 2-way conductor: pure copper electrode with a separate contact spring

In conventional designs the conductor itself had to provide the spring action, which made it impossible to use pure copper, the better-sounding material. The 2-way conductor construction gives the following benefits:

  1. A better-sounding conductor can be used.
  2. Reliable contact pressure is achieved.
  3. The electrode's contact pressure stays stable over the long term.

 

New electrode structure that increases contact area and doesn't damage AC plugs

Compared with the conventional type, the new electrode (blade receiver) folds back the part that would contact the AC plug blade sharply on insertion, and gives its tip a rounded radius. This solves the problem of AC plug blades being abraded and scratched, while also increasing the contact area, for full power delivery and a dramatic improvement in sound quality.

 

Construction

  • The nylon and glass fibre resin used in the body is mixed with nano-scale ceramic powder and carbon powder in a fixed ratio, which work together to damp vibration. The cover is polycarbonate. The ceramic converts vibration into electrical energy, and the carbon absorbs that electrical energy.
  • The electrodes use a uniquely shaped stainless steel wire pressure spring with a special coating, which raises the contact pressure on the blade receivers and suppresses vibration.
  • The wire connection screws use Furutech's own structure, with high holding force and a large contact area.
  • The mounting plate is 2mm-thick stainless steel, for vibration control and better sound, and is more rigid than in earlier products.
  • The outlet cover screw passes through the body and connects directly to the nut on the mounting plate. Tightening it applies tension that thoroughly eliminates losses caused by vibration (patent pending).

About Furutech

Japanese maker of plugs, connectors and cables, with its own treated copper conductors and shielding materials.

Furutech is a Japanese company based in Tokyo. Its catalogue covers power connectors in IEC, UK, Schuko and other formats, signal connectors such as RCA and XLR, finished power, speaker, line, digital, USB and HDMI cables, and power distributors. It also makes bulk cable and accessories for phono and disc treatment.

A cryogenic and demagnetising treatment

The Alpha Process combines cryogenic treatment with demagnetisation, and Furutech applies it to its alpha-treated pure copper. It sits alongside Ohno Continuous Cast single-crystal copper in the conductor line-up, so the Furutech catalogue includes more than one route to a pure copper conductor.

Copper, silver and hybrid conductors

Furutech's materials include silver-plated copper and copper-silver hybrids as well as OCC and alpha-treated copper. DUCC and PC-Triple C copper appear in some of its cables. This range of conductors means the same plug design can be paired with different cable types.

NCF material and interference absorption

Furutech describes its NCF, short for Nano Crystal Formula, as generating negative ions and converting thermal energy into far infrared energy. It also uses a material called GC-303 to absorb electromagnetic interference. These are Furutech's own descriptions of what the materials are designed to do.

Why we stock Furutech

We do not just sell Furutech, we build with them. Their plugs and connectors go onto the custom cables we make in our own workshop, including cables for other brands in our range. When you fit a component by hand several times a week, you find out quickly whether it is well made.
