Entreq Eartha Sudoku Ground Cable
The Eartha Sudoku Ground Cable sits at the top of the Entreq ground cable range for mainstream systems, sharing its core technology with the flagship Eartha Olympus but built using a new construction technique that produces a thinner, more flexible cable — useful where routing space is tight. It is a more budget-conscious route to the performance of Entreq's best ground cable technology.
Construction and Termination
All Eartha Ground Cables are terminated at one end with a hook connector for connection to an Entreq Ground Box. The other end is specified and hardwired as standard at the time of ordering, which Entreq state offers the best possible performance. If you prefer to use Entreq's Click Adaptor system, you can specify either a bayonet connector (Level 3) or a 3.5mm male connector (Level 1 or 2) at the time of ordering. The bayonet connection offers the next best performance level to hardwiring; the 3.5mm jack sits one level below that.
Materials
The Eartha Sudoku Ground Cable is built from wood, silver, tungsten and cotton — the same material combination Entreq use throughout their ground cable range to achieve effective earthing of unwanted noise from audio components.
Technical Specifications
table>Recommended Ground Boxes
Entreq recommend the following ground boxes for use with the Eartha Sudoku Ground Cable: Olympus X, Olympus X T, Olympus 10 T, Olympus Infinity T, Olympus TenTen, and Olympus Hero.
Who Is It For?
The Eartha Sudoku Ground Cable is for the listener who wants the technology at the heart of Entreq's flagship cable in a more manageable form — physically and financially. If you are already using an Entreq ground box at the Olympus level and want to push performance further without committing to the Eartha Olympus cable itself, this is the logical next step. The thinner profile also makes it a practical choice where cable routing is constrained.
