The S25 Speaker 415 is the versatile solution in the series, impressing both sonically and technically with neutrality, control, and dynamics. The multi-stranded multicore design reduces cable inductance, supporting precise and fast signal transmission. The sound features a defined, powerful bass foundation, cleanly layered mids, and a pleasant openness in the highs – never harsh, but present. The spatial imaging remains stable even at higher volumes. The cable is mechanically robust yet flexible – its unobtrusive jacket and moderate diameter allow for discreet integration into existing hi-fi setups, furniture, or cable ducts.

Sound doesn't start at the speaker
Speaker cables are much more than just wires between the amplifier and the speaker – they help determine how much of the music actually reaches you. Electrically, every cable acts like a filter made up of resistance, inductance, and capacitance. These properties influence whether details are preserved or whether highs lose brilliance and bass loses precision. Especially for speaker cables, conductor cross-section, copper quality, and construction are crucial for low-loss, dynamic signal transmission. The S25 series relies on high-purity OFC copper, thoughtful multicore designs, and flexible, durable materials. This keeps the music signal clear, true to impulse, and authentic – so you hear what’s really on the recording. A good cable doesn’t color the sound, it transmits it: It is the stable bridge between your components and musical expression.
Multicore technology: More control, more sound
A technical core feature of the S25 speaker cables is their multicore construction. Unlike conventional conductors, several fine-stranded individual wires run parallel to each other – this reduces cable inductance, improves high-frequency characteristics, and preserves the signal structure even during fast transients. The symmetrical distribution of the conductors also helps minimize interference, as magnetic fields partially cancel out. This is especially evident in the Speaker 415 and 425 models, resulting in tight, well-defined bass reproduction, precise soundstage imaging, and brilliant high-frequency detail resolution. The result: high impulse fidelity, greater control, and spatial sound that remains stable – even during complex passages.
OFC copper: Pure material for pure music
For the S25 series, we use only high-purity, oxygen-free copper (OFC) with a purity level of at least 99.95%. This material offers excellent electrical conductivity and reduces transmission losses – even over long cable runs or with high current flow. OFC copper is also highly resistant to corrosion, ensuring long-term sound stability. Combined with high-quality insulation materials and gold-plated connectors, the signal remains unaltered – from the amplifier output to the speaker terminals. S25 cables deliver music with high transparency and authentic dynamics – honest, direct, and without artificial coloration.
Crimp technology & gold-plated contacts
Connector joints are critical points in any signal path – they determine whether sound quality remains consistent. The S25 series uses professional crimp technology: fine-stranded copper conductors are gas-tight pressed under high pressure, effectively preventing corrosion and ensuring lasting contact stability. Gold-plated plugs provide consistently low contact resistance and are resistant to oxidation – even with frequent plugging and unplugging. This combination guarantees a reliable, sonically clean connection that neither swallows details nor slows down dynamics. For lasting sound fidelity – completely maintenance-free.

Well-engineered technology
The S25 series combines high-quality materials, thoughtful engineering, 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 S25 series cable leaves our workshop, it is individually tested for complete signal continuity. This ensures that every connection, from plug to conductor, functions flawlessly. This final inspection is part of our uncompromising commitment to quality – because even at the entry point to high-end hi-fi, every detail matters to us.
Manufacture 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 created 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 foil or excessive packaging. The sturdy cardboard packaging protects what matters: your listening experience. Because sound is not created by appearances, but by quality – honest, direct, and authentic.
