The latest design with a completely new construction method. Featuring a separate EEDS drain wire. The Entreq Sudoku Core Speaker Cable represents one of the finest speaker cable designs within Entreq’s acclaimed Core range, positioned above the Delphius series and just below the flagship Olympus collection. Created for reference-level audio systems, it has been engineered to preserve the integrity of the amplified signal at the most critical stage of the audio chain, where every nuance of musical information must be delivered accurately to the loudspeakers. Utilising advanced conductor materials, refined cable geometry, sophisticated dielectric technology and precision mechanical damping, the Sudoku Core is designed to minimise the perceived noise floor while maintaining outstanding tonal balance and coherence. Rather than emphasising detail, it removes subtle layers of interference, allowing music to flow naturally with greater realism, effortless dynamics and an immersive sense of space that brings performances convincingly to life. Energy Reference System with Precision Swedish Craftsmanship Every Entreq Sudoku Core Speaker Cable is meticulously handcrafted in Sweden and incorporates Entreq’s most advanced implementation of the Energy Reference System (ERS) alongside dedicated Corepoint technology. Working together, these innovations establish a stable electromagnetic reference around the cable, helping to reduce unwanted electrical interference before it can influence the amplified signal travelling to the loudspeakers. Compared with the Delphius Core range, the Sudoku Core delivers noticeably blacker backgrounds, holographic imaging, richer tonal colours and exceptional micro-detail, while preserving the smooth, natural presentation for which Entreq is renowned. Musical performances gain greater dimensionality, instrument placement becomes more precise and low-level ambience is reproduced with remarkable clarity. The result is a soundstage that feels expansive and realistic, with effortless dynamics and exceptional coherence across the entire frequency range. Built for No-Compromise Audio Systems The Entreq Sudoku Core Speaker Cable has been developed for audiophiles who demand the highest levels of performance from already exceptional systems. Designed to integrate seamlessly with Entreq’s wider ecosystem of Corepoint technology, grounding products and vibration control solutions, it forms part of a comprehensive approach to electromagnetic field management throughout the entire audio chain. As systems become increasingly revealing, the advantages of the Sudoku Core become even more apparent, delivering greater transparency, natural timbre and an enhanced sense of musical engagement without sounding analytical or exaggerated. Positioned between the highly accomplished Delphius Core and the ultimate Olympus flagship range, the Sudoku Core Speaker Cable offers an outstanding balance of reference-level refinement, long-term upgrade potential and uncompromising musical performance, making it an exceptional choice for listeners seeking the finest possible connection between amplifier and loudspeakers.
