Entreq Eartha Infinity Sudoku Ground Earth Cable

The Entreq Eartha Infinity Sudoku Ground Earth Cable is designed to deliver highly effective grounding performance for hi-fi systems while remaining practical and accessible for a wide range of installations.

Based on the advanced grounding technology used in Entreq’s flagship Eartha Olympus cables, the Sudoku model provides many of the same sonic benefits in a more streamlined and affordable design. By offering an efficient pathway for unwanted electrical noise and stray voltages to exit your audio components, the cable helps reduce background interference within your system.

The result is a cleaner, more stable soundstage with improved clarity, dynamics, and detail retrieval. By lowering the overall noise floor of your system, the Eartha Infinity Sudoku Ground Earth Cable allows music to emerge with greater precision and realism.

Tungsten-Enhanced Construction for Improved Noise Drainage

At the core of the Entreq Eartha Infinity Sudoku Ground Earth Cable is a carefully engineered internal structure designed to maximise grounding efficiency. The cable incorporates Entreq’s “Tungsten Inside” technology, which utilises specially selected materials and conductor design to enhance the cable’s ability to absorb and drain high-frequency noise.

This design helps minimise the impact of electromagnetic interference and stray voltages that can circulate through modern audio systems. Compared with the flagship Olympus models, the Sudoku cable features a refined construction technique that produces a slimmer and more flexible cable profile.

This makes installation easier, particularly in systems where space behind equipment racks is limited. Despite its reduced thickness, the cable retains excellent performance characteristics and remains a highly capable grounding solution.

Flexible Installation and Termination Options

The Entreq Eartha Infinity Sudoku Ground Earth Cable is designed for straightforward integration with Entreq grounding systems. One end of the cable features a hook connector that attaches directly to an Entreq ground box, creating a secure and stable grounding path.

The opposite end of the cable is normally supplied with a fixed termination selected at the time of ordering, providing the most direct connection and therefore the highest level of performance. The standard cable length is 1.65 metres, making it suitable for most system layouts, while additional lengths can be supplied in 0.55 metre increments if required.

For greater installation flexibility, users may also specify a bayonet connector or a 3.5mm connector instead of a fixed termination, offering adaptable connectivity without compromising grounding efficiency.

Click Adaptor Compatibility for System Versatility

For users who require a modular connection solution, the Entreq Eartha Infinity Sudoku Ground Earth Cable can be ordered with a 3.5mm connector to support Entreq’s Click Adaptor system. These adaptors allow the cable to connect to a wide variety of components and interfaces throughout your audio system.

Available Click Adaptor types include RCA, USB-A, USB-B, RJ45, Spade, XLR Male, XLR Female, UK 3 Pin, EU Schuko, and US Nema connections. Each adaptor is carefully manufactured using materials selected for their low electromagnetic interaction, helping maintain optimal grounding performance.

This modular system allows a single grounding cable to be easily adapted as your system evolves or expands. To view our range of Click Adaptors, Click Here.
