El AudioQuest Forest Digital Coax is a coaxial cable de 75 ohms designed for digital signal transmission S / PDIF between audio players and converters. Its function is to minimize the jitter and distortion during digital data transfer, ensuring that the information reaches the DAC with maximum integrity. It uses solid copper conductors with 0,5% silverIt features nitrogen-injected hard-cell foam insulation and a layered metal noise dissipation system. It is aimed at audiophiles seeking a reliable, low-noise digital connection between CD transportsBlu-ray players, streamers, DAC's o AV receivers.
Drivers solid copper with silver plating
This cable uses solid conductors instead of stranded ones, a choice that reduces distortion from strand-to-strand interaction. The copper core with a 0,5% silver It improves conductivity at higher frequencies in the digital spectrum, where the skin effect tends to degrade the signal.The caliber used is 0,2 mm² (24 AWG)a balanced thickness that maintains the exact impedance of 75 ohms required by the S/PDIF standard. Deviations from this value can cause signal reflections and increase jitter, especially in runs longer than one meter.
Why does this matter in practice? Because jitter—temporal variations in the reception of the bits—directly affects the reconstruction of the analog waveform in the DAC. Less jitter results in a more stable stereo image, more natural timbres, and an overall sense of 'order' in the presentation.
The soldering of the terminals is done by cold-welded crimpingavoiding the heat that could alter the molecular structure of the copper and generate micro-discontinuities in the transmission.

Isolation Hard-Cell Foam with nitrogen
The dielectric used is a hard-cell foam injected with nitrogen, a material with a very low dielectric constant that minimizes capacitive losses. In practical terms, this means that the digital signal travels through the conductor with less electrical resistance.Conventional dielectric materials like solid PVC absorb some of the signal energy and delay its propagation unevenly depending on the frequency. This adds temporal dispersion and increases jitter. Hard cell foam virtually eliminates this phenomenon.
The result is a cable that maintains the integrity of the digital flanks even over runs of several meters. If your transport and DAC are separated by distance, or if you need to run the cable behind a piece of furniture with several bends, this shielding ensures that the signal arrives without temporary degradation.
Furthermore, the low dielectric absorption causes the signal reflected off mismatched impedances to attenuate faster, reducing internal echoes that can contaminate the bits.

System Noise Dissipation in Metallic Layers
The AudioQuest Forest incorporates the system NDS (Noise-Dissipation System) of metallic layers, a technology that drains the radio frequency noise induced in the shielding to the ground without allowing it to contaminate the central conductor.The braided screen of tin-plated aluminum It rejects external interference (Wi-Fi networks, switched-mode power supplies, radio stations), but at the same time, it can act as an antenna and generate stray currents. The NDS channels these currents to an intermediate metal layer that dissipates them before they reach the signal conductor.
In practice, this translates to a quieter black background. In mid-to-high-resolution systems, RF noise can appear as a veil over the sound image or as 'grain' in quiet passages. By eliminating this noise from the cable itself, the DAC receives a cleaner signal and can reconstruct the waveform with fewer artifacts.
It is especially useful in home environments saturated with wireless devices, where RF density is high and cables act as unintentional capture points.
Connectors RCA with gold-plated contacts
The Forest's male RCA connectors are equipped with contacts gold platedA coating that prevents oxidation and ensures a stable, long-term connection. Gold does not corrode or form insulating layers, unlike unprotected nickel or silver.Crimping is done by cold-weldingThis is a high-pressure mechanical process that fuses metal without applying heat. This prevents the formation of weld points with varying electrical resistance, which can act as micro-diodes and generate intermodulation distortion in the digital signal.
What's the impact of this? A more consistent connection over time. Tin-soldered connectors tend to crack with thermal cycling, especially if the equipment is frequently turned on and off. Cold crimping eliminates that risk.
The outer cover combines Black PVC with green stripesfacilitating visual identification between several cables of the same system.
Compatibility with transports, DACs and AV receivers
The Forest Digital Coax is compatible with any equipment that uses a connection 75 ohm coaxial S/PDIF, the most widespread digital standard in home audio. You can use it to connect:- CD transports to independent external DACs
- Blu-ray Players to integrated amplifiers with digital input
- Network streamers to high-resolution converters
- AV Receivers with coaxial output to recording systems or processors
The precise impedance of 75 ohms Ensure there are no signal reflections at the interface, a critical requirement for keeping jitter low. Cables with incorrect impedance (e.g., reused composite video RCA cables) may appear to work fine, but they accumulate temporary errors that degrade the quality of the D/A conversion.
If your system uses multiple digital sources, the Forest is a coherent option for unifying the quality of connections without investing in higher-end solutions whose benefit is only noticeable in reference equipment.
