The Supra EFF-I is a high-performance analogue interconnect designed to deliver uncompromised transmission of the finest audio details with precision timing, setting a new standard in transparency and fidelity. With Supra’s proprietary Equalized Frequency Flow (EFF) technology, EFF-I addresses the challenges of skin-effect and phase distortion, resulting in pristine audio clarity even at the highest frequencies.
A standard interconnect cannot achieve this level of transmission quality. The Supra EFF-I leverages advanced passive design techniques, employing a unique tube-shaped conductor that minimizes the impact of skin-effect across the entire audible range. By winding silver-plated strands around a plastic core, we create a 0.20 mm wall thickness—precisely calibrated to equalize impedance for all frequencies and prevent signal degradation.
The silver plating serves two key functions: it reduces impedance at ultra-high frequencies, where signals tend to travel along the conductor’s surface, and it minimizes phase distortion caused by electron jumps between strands. The result is a cable that faithfully transmits every nuance of your music, maintaining the balance and detail of each frequency as originally intended.
With numerous awards, the EFF-I stands as one of Supra’s most celebrated cables, and for good reason. Its equalized impedance and low phase shift offer an extraordinary level of transparency, capturing the delicate nuances and room acoustics of every recording. This interconnect is perfectly suited for balanced and single-ended analogue transmissions in mid- to high-end Hi-Fi setups, delivering unrivaled clarity and dimension.
Available in a range of standard lengths as well as custom builds, the Supra EFF-I is equipped with high-quality connectors for optimal versatility:

The Effective Frequency-Related Signal Flow Depth (or Skin Effect) describes how the depth at which electric current flows in a conductor decreases with increasing frequency. This phenomenon impacts electric conductivity because higher frequencies cause the current to concentrate near the conductor’s surface, increasing impedance and potentially altering signal integrity.
Here’s an example of Skin Depth at different frequencies:
These values illustrate that at lower frequencies (e.g., 20 Hz), the current flows through a larger cross-sectional area of the conductor, maintaining lower impedance. As frequency rises, the skin depth decreases, concentrating the signal near the surface and increasing impedance.
Understanding and compensating for skin effect is crucial in high-end audio cable design to ensure uniform signal transmission across frequencies, thus preserving signal clarity and integrity, particularly for higher frequencies in audio applications.
