ETI Research Coda Pure Silver RCA Connectors

The audio landscape is constantly evolving, and the introduction of the Coda RCA connector marks a significant milestone in high-fidelity sound. Building on the reputation of the acclaimed Silver LINK, which has long set the standard as one of the finest RCA connectors available, the Coda RCA takes audio connectivity to new heights. ETI Research has focused not only on refining the connector itself but also on addressing the critical issues of electromagnetic and radio frequency noise rejection. This enhancement is particularly relevant given the challenges faced in audio equipment since the original Bullet design by Rob Woodland.

Unprecedented Noise Rejection and Shielding

A major advancement lies in the brass housing, which provides an effective shield against unwanted electromagnetic interference. In an age where audio fidelity can easily be compromised by various noise sources, the Coda ensures that the audio signal remains pure and untainted. This carefully engineered design enables audiophiles and music enthusiasts to enjoy a listening experience that is clear, detailed, and free from distractions.

Distinct Design Features That Elevate Performance

What sets the Coda apart from typical silver RCA connectors is ETI Research’s commitment to superior materials and innovative design principles. Unlike larger, bulkier connectors that may be easier and cheaper to produce, the design focuses on minimising mass to reduce unwanted effects on sound quality. Excess mass can lead to increased capacitance and resistance, ultimately distorting audio performance.

Each Coda RCA connector is meticulously machined to reduce mass wherever possible. In fact, more silver is removed during production than is retained, resulting in a lightweight yet highly effective connector. The Coda RCA features a hollow construction with 0.6 mm-thick walls, combining durability and minimalism without compromising sonic performance—a significant improvement over many imitations on the market.

The return pin is hand-assembled, enhancing both durability and reliability under repeated use. This attention to detail reflects ETI Research’s dedication to producing connectors that not only perform exceptionally but also stand the test of time.

Exceptional Silver Quality for Superior Sound

A standout feature of the Coda RCA is its use of pure silver. Unlike many competitors who rely on silver-plated alternatives, the Coda is crafted from unplated, high-quality pure silver sourced directly from a specialised foundry in England. This commitment to quality ensures exceptional conductivity, resulting in optimal audio performance.

ETI Research provides an assay report verifying that the silver used is 99.99% pure. While some products may claim higher purity at lower prices, achieving such levels is both technically demanding and costly. ETI Research prioritises transparency and accountability, ensuring that every claim regarding material purity is independently verified.

The industry standard for silver purity is generally accepted to be 99.99%, and ETI Research encourages consumers to request assay reports when comparing alternatives. By using only pure silver connectors, ETI Research sets pricing in line with current commodity market spot rates and works diligently to maintain stability for both the Silver LINK and the Coda RCA, adjusting only in response to genuine fluctuations in raw material costs.
