Power cables featuring QR/BB™ technology, such as the Omega-X QR and Sigma-X QR, act as electric charge reservoirs. They store and release energy to enhance a component's access to instantaneous current, improving dynamics and reducing strain—particularly in high-powered amplifiers.

NR cables incorporate multi-stage filter networks designed to measurably reduce power-line and component-generated noise. This results in improved clarity and purity of sound across all connected electronics, including amplifiers, sources, and line-level components.

XC-designated cables are engineered to deliver unrestricted high currents, making them ideal for connecting power distributors or conditioners to wall outlets. They focus on continuous current delivery without incorporating noise reduction filters, ensuring that power-hungry components receive the necessary energy for optimal performance.
