Viablue NF-S1 Interconnect Cables; Pair

The Viablue NF-S1 Interconnect Cable is engineered to transmit audio signals exactly as they were recorded. It delivers clean bass, highly detailed highs, and transparent imaging with no coloration or distortion. Every component in the signal chain plays a role, and the NF-S1’s precision-engineered internal geometry ensures that nothing gets lost or smeared in translation.

To achieve this level of fidelity, the NF-S1 relies on a mix of material science and cable architecture. Each channel includes two inner conductors made from tinned oxygen-free copper (OFC), supported by multiple layers of shielding and polyethylene insulation. This design provides high conductivity, optimal damping, and full-spectrum clarity across the frequency range.

Key Features

• Dual Conductor Layout: Two inner tinned OFC copper conductors, each with 19x 0.19 mm strands
• Four-Layer Quattro Silver Shielding: Combines 2 silvered spiral shields and 2 ALU-PET foils to block EMI/RFI
• Polyethylene Dielectric: Low-loss insulation maintains signal linearity and speed
• Premium Connectors: VIABLUE™ T8 RCA and XLR plugs, 24k gold-plated for maximum conductivity
• Ferrite Noise Filter: VIABLUE™ Ferrite Filter 9 minimizes high-frequency interference
• Cobra Braided Sleeving: Provides a flexible, durable, and attractive finish
• Handmade in Germany: Assembled with precision and subjected to rigorous quality control

Precision Shielding for Signal Purity

At the heart of the NF-S1 is its Quattro Silver shield design. This multilayered approach surrounds the dual conductors with two layers of silvered copper spiral shielding and two additional layers of ALU-PET foil. Combined, these shields create a highly effective barrier against external noise, preserving microdetail and spatial accuracy. It’s an ideal setup for complex analog signals, particularly where long cable runs or interference-prone environments are involved.

Conductors and Dielectric

The NF-S1 employs tinned oxygen-free copper (OFC) conductors, 19 strands per conductor, optimized for linear signal transmission. Each conductor is surrounded by polyethylene insulation, which offers low capacitance and superior electrical stability. This combination ensures a neutral sound signature with no artificial brightness or haze.

Configuration Options

The NF-S1 is available in mono cable pairs (one left, one right) with either RCA or XLR terminations. 

• RCA to RCA
• XLR to XLR
• RCA to XLR
• XLR to RCA

Each channel is fully shielded and separated, maintaining channel integrity and allowing for precise stereo imaging.

Handmade in Germany

Every NF-S1 interconnect is handmade at VIABLUE’s facility in Germany. This craftsmanship ensures uncompromising quality control, perfect assembly tolerances, and consistency across every cable produced. These cables are the result of over two decades of engineering refinement, built for systems that demand transparency and accuracy.

The Listening Room Difference

We partnered with Viablue for their exceptional craftsmanship and commitment to performance. Each cable is meticulously built in-house in Germany, with rigorous oversight and quality control that ensures every product delivers the transparency and reliability we expect in our systems. And let’s be honest, we love gooooollllddddd.
