A cable that meets the correct construction standard for its application performs its function completely. It transmits the signal without alteration, addition, or loss. That standard includes correct characteristic impedance, appropriate shielding geometry, proper termination, and conductor gauge matched to the load. These are engineering requirements, verifiable by measurement.
Topology, Materials, Construction
Topology determines the electrical arrangement of conductors. Twisted-pair reduces interference by cancelling magnetic fields. Star-quad extends this with four conductors, improving common-mode rejection across two axes. Topology is selected for the application, not for appearance.
Conductor gauge is determined by load and run length. In speaker cables, larger cross-section reduces resistance and preserves damping factor. In interconnects, gauge has no audible effect when shielding is correctly implemented.
Copper is our reference conductor. High conductivity, mechanical stability, practical cost. Silver provides only marginal conductivity advantage and no audible benefit at audio frequencies. One exception: S/PDIF coaxial cables use silver-plated copper to maintain 75Ω impedance. USB cables are built to 90Ω, Ethernet to 100Ω, AES/EBU to 110Ω.
Dielectric materials influence capacitance. In phono applications, excessive capacitance alters high-frequency response. We select insulation to maintain capacitance within the correct range. Claims regarding dielectric "memory" or "charge" are not supported by measurement.
Where required, we combine copper braid and oversized spiral windings with aluminum mylar foil for high RFI/EMI rejection while maintaining flexibility. Coverage below 85% introduces measurable gaps. This is a primary determinant of real-world performance.
Connectors
Connectors are frequently the weakest point. Impedance discontinuities and poor soldering introduce measurable degradation. We specify professional-grade connectors assembled under controlled conditions.
Gold plating resists oxidation — appropriate for fixed installations. Silver plating offers lower contact resistance — preferred where connections are regularly maintained. KLEI Copper Harmony RCA connectors employ silver plating with consistent-pressure contact geometry.
Where Specification Matters
In S/PDIF, maintaining 75Ω prevents reflections and timing errors. In phono systems, total capacitance must match cartridge specs — moving-magnet typically requires 100–200 pF including tonearm wiring.
In long speaker runs, cable resistance relative to loudspeaker impedance affects damping factor. We specify 6mm² as reference cross-section.
In balanced XLR, common-mode rejection ratio defines performance. In USB, controlled impedance and correct conductor pairing are required for data integrity.
We favor active loudspeaker systems where possible. When the speaker cable is eliminated entirely, one variable is removed. Systems such as Lipinski Sound implement crossover and amplification in full Class A without passive components in the signal path.
Grounding and System Noise
Grounding is the primary source of noise issues. A ground loop occurs when components reference ground through multiple paths at different potentials. Resolution requires correction of the grounding scheme — lifting ground, implementing balanced connections, or galvanic isolation. We address grounding as part of system evaluation.
Sonic Differences
Differences arise from measurable factors: shielding effectiveness, impedance accuracy, termination quality. Price is not a technical variable.
Mains and signal cables should be separated. Tight coiling should be avoided. Balanced and unbalanced lines should be routed independently.
We do not ask to be trusted. We ask to be heard. In a field where claims often exceed evidence, we prioritize demonstration over assertion.
Questions about Our Engineering Standard
Why does love cable use copper instead of silver conductors? +
Copper offers high conductivity, mechanical stability, and practical cost. Silver provides only a marginal conductivity advantage and no audible benefit at audio frequencies. Its oxidation characteristics make it unsuitable for our objectives.
The exception is S/PDIF coaxial cables, where silver-plated copper maintains the required 75Ω impedance.
What gauge speaker cable do I need? +
We specify 6mm² as the reference cross-section. At this size, resistance remains low enough to preserve amplifier damping factor over typical runs of 8–10 meters into 4Ω loads.
Smaller conductors may perform adequately in short demonstrations but do not maintain performance in real installations.
Why does shielding matter in audio cables? +
We combine copper braid and oversized spiral windings with aluminum mylar foil for high rejection of RFI and EMI while maintaining flexibility. Coverage below 85% introduces measurable gaps in effectiveness.
Shielding is a primary determinant of real-world performance.
How do I fix ground loop hum? +
A ground loop occurs when components reference ground through multiple paths at different potentials. Resolution requires correcting the grounding scheme — lifting ground at one end, implementing balanced connections, or applying galvanic isolation.
This is cost-neutral and produces immediate, repeatable results.
