Product information "S25 Digital Cable | RCA"


The S25 Digital Cable meets the highest standards of sonic fidelity and technical precision in digital signal transmission. With its precisely matched impedance of 75 ohms, it is perfectly suited for all common digital audio interfaces and guarantees lossless, low-jitter transmission - even with high-resolution formats. The signal conductors are made of highly pure, oxygen-free OFC copper and insulated with foamed polyethylene (PE). This dielectric, containing microscopically enclosed air bubbles, ensures particularly low capacitance, minimizes signal loss, and preserves the integrity of even the finest digital signals.

A dense copper braid made of 186 fine strands effectively shields the signal from external interference such as Wi-Fi, Bluetooth, or mobile networks. The robust, highly flexible construction and discreet design allow for easy and seamless integration into any hi-fi system. Gold-plated solid metal connectors ensure consistently low contact resistance and reliable connectivity - even after many plug cycles. Each cable is manufactured in Germany and individually tested for signal continuity to ensure uncompromising quality and long-lasting performance.

Digital precision starts with the cable

Digital cables are far more than simple connections – they determine how reliably and accurately digital audio signals are transmitted between your components. Especially with high-resolution formats, every detail matters: even minor interference or reflections can lead to audible errors, jitter, or data loss. The Connect 212 Digital from the S25 series relies on high-quality materials and a design precisely tailored to digital audio applications. This keeps the signal stable, clear, and free from digital artifacts – delivering a listening experience that stays true to the original.

Precise impedance

One of the key quality factors of a digital cable is its impedance. For digital audio connections, an exact value of 75 ohms is essential — only then can reflections and signal loss be effectively avoided. Even slight deviations can cause jitter and compromise sound quality. The Connect 212 Digital is precisely matched to 75 ohms, ensuring interference-free, bit-perfect transmission — even over long cable runs or in demanding setups. This keeps your music consistently transparent, dynamic, and true to detail.

  • "A good cable is like an interpreter between the artist and the listener: The more neutral and precise it works, the closer you are to the original. That’s exactly what we aimed for with the S25 series."

    Product developer Holger Wachsmann

Foamed PE: optimal dielectric

The dielectric — the insulating material inside the cable — significantly influences how low-loss digital signals are transmitted. Air is the best dielectric after vacuum, which is why the Connect 212 Digital uses foamed polyethylene (PE): microscopic air bubbles provide a particularly low dielectric constant and extremely low capacitance. The result is minimal signal loss, high transmission speed, and clear, uncolored signal flow — for maximum precision with every piece of music.


High-density shielding: prevents interference

Digital audio signals are sensitive to electromagnetic interference — from sources like Wi-Fi, Bluetooth, or power supplies. The Connect 212 Digital protects your signal with a tightly woven copper braid made of 186 individual strands, providing highly effective shielding against external influences. This keeps the signal free from hum, noise, and digital errors. The combination of OFC copper, foamed PE, and dense shielding ensures your music arrives exactly as it was sent: clear, uncolored, and interference-free.

    Thoughtful engineering

    The S25 series combines high-quality materials, intelligent design, and skilled craftsmanship into an audiophile cable concept that makes high-end sound accessible to newcomers.

Every cable a promise: Quality assurance in the S25 series

Before any cable from the S25 series leaves our manufacturing facility, it is individually tested for complete signal continuity. This ensures that every connection from the plug to the conductor functions flawlessly. This final inspection is part of our uncompromising commitment to quality – because even at the entry level of high-end hi-fi, every detail matters.

Manufacturing quality for entry into high-end

The S25 series was developed as an entry point into the world of high-end hi-fi – 100% made in Germany. Each cable is produced in our in-house workshop: carefully handcrafted, individually tested, and technically refined down to the last detail. We invest in high-quality materials, solid expertise, and genuine craftsmanship – not in glossy wrapping or excessive packaging. The sturdy cardboard packaging protects what matters most: your listening experience. Because sound doesn’t come from appearances, but from quality – honest, direct, and authentic.

High End RCA connector Quality: Exzellenz Suitable for S25 cables

The S25 Connect RCA plug is suitable for custom assembly of audio, digital, and subwoofer cables. Unlike simple tin-plated RCA plugs with plastic housings, its contact material is made of solid brass with excellent conductivity. The gold-plated contacts are permanently protected against corrosion. For stability and a timeless appearance, the precisely machined sleeve is made of solid aluminum, turned, glass bead blasted, and anodized. It provides mechanical protection for the transition zone between cable and plug while also reducing interference. The connector is designed for cables with a diameter of up to 8.5 mm, giving you flexibility in the choice of cable.
