Oehlbach Black Connection digital 2m
Overview
Oehlbach’s Black Connection Digital is an RCA coaxial cable that stands out for its exclusive technologies and uncompromising construction, designed for the most demanding hi-fi systems and home theater setups where every detail matters in sound reproduction.
Exclusive Technologies: HPOCC and Silver Gap
At the heart of this cable lies HPOCC (High Purity Oxygen-Free Copper) technology, using monocrystalline copper that is completely oxygen-free. This exceptional purity eliminates impurities that can degrade the digital signal along its path.
The major innovation is the Silver Gap HPOCC process, exclusive to Oehlbach. During the casting process, the natural monocrystalline transitions in the copper are filled with pure silver. This technique creates a virtually smooth conductor at the molecular level, generating ideal electrical conditions for high-frequency digital signal transmission.
Construction and Shielding
The Black Connection Digital employs sophisticated quadruple shielding, combining two aluminum foils and two copper braids arranged in successive layers. This architecture effectively protects against electromagnetic and electrostatic interference that pollutes the modern home environment.
The cable’s geometry maintains a constant characteristic impedance of 75 ohms, the required standard for digital coaxial connections. This technical precision ensures the absence of unwanted reflections that could compromise audio data integrity.
The 7.5 mm diameter and minimum bending radius of 60 mm demonstrate the cable’s robust construction, while preserving the flexibility needed for home installations.
Applications in Hi-Fi and Home Theater
This cable is naturally suited for connections between digital sources and DAC converters, or between CD/network players and amplifiers equipped with coaxial inputs. Its design is particularly optimized for transmissions to external DACs, sensitive components where input signal quality directly influences performance.
In home theater setups, the Black Connection Digital excels in high-fidelity connections, especially for critical audio sources such as audiophile CD players or high-end network streamers.
The 75 cm length is ideal for compact installations where components are close together, a common situation in quality hi-fi systems.

Frequently Asked Questions
What audible difference can be expected compared to a standard digital cable?
In a well-designed high-fidelity system, improvements include reduced background noise, better instrument separation, and less listening fatigue. The effect depends greatly on the quality of the surrounding components and the room’s acoustics.
Is this cable compatible with all devices equipped with coaxial outputs?
Yes, the Black Connection Digital complies with the S/PDIF standard and works with all equipment featuring RCA coaxial inputs/outputs: CD players, DACs, amplifiers, audio interfaces, etc. The 75-ohm impedance is universally compatible.
How can the price be justified in light of claims that “digital is all or nothing”?
While data is binary, its transmission remains analog and sensitive to interference. Cable quality influences jitter, noise, and clock quality—measurable parameters that affect the performance of the receiving DAC.
Is this cable suitable for high-resolution formats like DSD or 24/192 PCM?
Absolutely. The bandwidth and impedance precision of the Black Connection Digital support all current digital formats transmitted via S/PDIF coaxial connection, including high resolutions up to the standard’s limits (generally 24-bit/192 kHz).
