Oehlbach Series 1 RCA 2m

The Series 1 RCA from Oehlbach is an audio cable made in Germany, designed for audiophile and professional applications. It uses HPOCC single-crystal copper and a balanced construction, combined with triple shielding to limit interference. The product comes with a 30-year warranty, in line with the manufacturer’s sustainability policy.

Premium construction and exceptional materials

The Series 1 stands out through its use of silver-plated copper (SPC) internal conductors featuring HPOCC (High Purity Ohno Continuous Cast) technology. This continuous casting technique produces single-crystal copper of exceptional purity, virtually eliminating material transitions within the metal structure. The silver plating of the conductors further improves electrical conductivity, particularly at high audio frequencies.

The cable’s balanced geometry ensures perfect balance between the left and right channels, contributing to a precise and stable stereo image. This balanced construction, rare at this price point, minimizes distortion and optimizes channel separation.

The generous 14 mm diameter reflects the robustness of the construction, incorporating multiple protective layers while maintaining sufficient flexibility for installation. The 120 mm minimum bend radius indicates a solid construction that preserves signal integrity even in constrained installations.

Triple-layer shielding

The triple-layer shielding system is one of the Series 1’s key strengths. This multilayer protection includes an aluminum foil and two copper braids, creating an effective barrier against electromagnetic and electrostatic interference.

This professional approach is particularly relevant in modern home environments, saturated with electronic devices that generate noise. The aluminum shielding acts as a first barrier against high-frequency interference, while the copper braids neutralize low-frequency disturbances and provide a stable ground.

The combination of these three protective layers guarantees pure audio transmission, even near digital equipment, LED lighting, or Wi-Fi networks that may interfere with the analog signal.

RCA connectors and 24-carat gold finish

Solid metal RCA connectors with 24-carat gold plating ensure an optimal and durable connection. This gold finish offers exceptional resistance to oxidation and corrosion, ensuring consistent contact quality over the years. The 12 mm diameter connectors fit RCA standards perfectly while providing a comfortable grip when connecting and disconnecting.

Optimized electrical performance

The Series 1’s electrical characteristics reveal meticulous design. The 45 pF/m capacitance remains low enough to preserve high-frequency detail, while the 110 Ω characteristic impedance at 1 MHz meets professional standards for analog audio transmission.

These optimized electrical parameters enable faithful audio signal transmission across the entire audible bandwidth, without noticeable attenuation of extreme frequencies. Low parasitic capacitance preserves dynamics and fast transients, crucial elements for music reproduction.

Premium positioning and value for money

The Series 1 is positioned in the premium segment of the RCA cable market. This price reflects the use of exceptional materials (HPOCC copper, silver plating), the complexity of the balanced construction and triple shielding, as well as German manufacturing quality.

Compared with competing models at the same level, the Series 1 offers a set of technical features rarely found together at this price point. The 30-year warranty significantly strengthens the value proposition by reducing long-term cost of ownership.
