RCA, XLR, DIN, Headphone, DC & BNC Connectors

The new KLE Harmony series of RCA connectors gives audiophiles yet another choice in low-mass RCA connectors. This new design by Keith Louis Eichmann (KLE) comes in three flavors. The first version called the Copper Harmony is a pure copper base version, with silver plating for both the signal and ground/return pins.

The second version VH Audio stocks is the PURE Harmony. This version claims to achieve an IACS of 106% for BOTH the signal pin, as well as the ground/return pins.

The third version VH Audio stocks is the ABSOLUTE Harmony, which is similar to the Pure Harmony, but has an IACS that is claimed to have an IACS conductivity greater than 106%.

The newest, top-of-the-line version is the PERFECT Harmony RCA connector. This RCA construction uses proprietary mathematical modeling for the Perfect Harmony's ground to signal pin relationship, parameters, and determines the proprietary metallurgical processes that are used. The conductive pins incorporate highly conductive materials, such as copper and silver metallurgical layering processes as determined by KLEI's proprietary mathematical modeling.

A nice addition to these connectors is the inclusion of a soft, pliable rubber grommet with an ID of about .14" that can 'stretch' around smaller O.D. cables. Without the rubber grommet, the I.D. of the cable entry portion of the barrel is about .385". Two grub screws also help secure this connector to your cables, for additional peace-of-mind, when it comes to strain relief, and protecting against breakage.

Yet another great choice for fine wire, low mass DIY RCA interconnects like the VenHaus DIY Silver recipe.

Each package contains 2 pairs of RCA plugs (4 total plugs). >> Rubber grommets for rear of RCA are no longer included - they are now offered separately <<

The new ETI Research LINK RCA Connectors are based upon the original Bullet Plug RCA from ETI Research, but are now improved with new benefits.

For the standard LINK RCA: The hollow central signal pin is now made from pure, unalloyed copper (vs Tellurium Copper) for even better conductivity. The ground/return conductor pin is constructed with tellurium copper, to maintain strength. Both metal components are gold-plated for excellent conductvity, and to keep corrosion-free. Also included in the new LINK design is a metal housing with TWO grub screws that better secure the connector's strain relief to the outer jacket of your RCA cable.

For the SILVER LINK RCA: The hollow central signal pin is still made from solid, pure, unalloyed silver (just like the Silver Bullet) for the best conductivity. The ground/return conductor pin is also constructed with pure, solid silver. Also included in the new LINK design is a metal housing with TWO grub screws that better secure the connector's strain relief to the outer jacket of your RCA cable. It also imrpoves upon the original Bullet plug by extending the outer portion of the housing towards the tip of the RCA, essentially providing a shield for the RCA plug's entire internal wiring.

Each 4-pk contains 2 pairs of LINK RCA Plugs (4 total plugs), or you may optionally order a 2-pk (single pair). Please specify what color code you want for the pair, in the 'special instructions' section of the online checkout.

The LINK RCA plugs work superbly with DIY IC's, like the VenHaus DIY Silver interconnect recipe. Each package contains 2 pairs of RCA's (4 total plugs).

The WBT-0102 and WBT-0152 Nextgen RCA plug utilizes conductor material made of pure copper, and then direct gold plated. The silver version is made of pure silver. Fits cable up to 9.1 mm dia. (WBT-0102 series) or 11.3 mm (WBT-0152 series). Sold in a kit of 4, and includes WBT solder and Torx key.

The Nextgen RCA plug has gone through a few revisions since its introduction, and the latest versions offered (WBT-0102 and WBT-0152) use metal bodies. Cost is slightly more than the WBT-0110, but the added rigidity and robustness of the connection is well worth the few extra $$, IMHO.

The WBT-0102 will accomodate cable diameters up to 9mm, while the WBT-0152 will accomodate cable diameters from 9.1 to 11.3 mm. The WBT-0152 is slightly longer than the WBT-0102 (55mm vs. 51 mm), and both have black bodies.

The WBT-0114 Nextgen RCA Plugs is constructed of Ultramid® and available in nine different colors for multi-channel identification. The barrel is made of brass and finished in a matte black galvanized finish. The contact elements are made of high-purity copper, second only to silver, in order to ensure optimum signal transmission. Conductor metal is nickel free and gold plated to protect the surface from oxidation and to ensure contact quality.

Coda XLR: The Pinnacle of High-Performance Connectors. The new Coda XLR, is a premium solid silver XLR connector with brass housing, designed for audiophiles seeking the ultimate in sound quality. Both the male and female pins are crafted from pure silver, ensuring uncompromising performance—these are not merely silver-plated, but piure, solid silver. For those who demand the most transparent connection.

A Word of Caution Regarding the Coda XLR

While the Coda XLR is the most conductive option on the market, it is also the most delicate. The challenge lies in the fact that male XLR pins from different manufacturers vary slightly in diameter. To accommodate this, we design our female XLR connectors with a cross-hatch—a small cut at the end—allowing slightly larger pins to be inserted without damaging the metal.

However, the Coda, made from silver, is particularly fragile. It can’t be too tight, or the metal will tear; if it’s too loose, it may not work well with certain male XLR connectors. This results in some users finding it a perfect fit, while others may feel it’s too loose. Although we’ve tested it with a variety of XLR brands and haven’t found any compatibility issues, the Coda female connector will never offer a very tight fit for some but still will work perfect.

It is best suited for those with significant experience. If you’re accustomed to brass connectors, I would recommend choosing the Kryo model, which features silver plating and offers more durability.

Furutech FP-681M and FP-682F chassis mount XLR sockets are considered significant upgrades over what is currently available on the market.
