Entreq Delphius Speaker Cables The Delphius Speaker Cable is Entreq's flagship speaker cable — hand-built in Sweden around the new Energy Reference System (ERS) and Corepoint technology. By the time signal reaches your speaker cables it has passed through every component in your system and arrived at its most exposed point: amplified, current-rich, and open to the electromagnetic environment of the room itself. Delphius is designed to address that vulnerability directly. Energy Reference System (ERS) At the core of the Delphius Speaker Cable is the Energy Reference System — a separately shielded reference wire that works in concert with the Corepoint Signal units supplied with every cable. Where a conventional drain wire carries induced noise away, ERS interacts with the electromagnetic field around the cable. The Corepoint provides the stable reference point that allows it to do so. Each channel is supplied with its own Corepoint unit, ensuring left and right operate with matched coherence across the full length of the cable run. In our experience, the discipline of matched coherence between channels is not a minor detail. It is the kind of thing that becomes apparent only when it is absent — a subtle but persistent loosening of the relationship between instruments, a slight blurring of the space between them. Delphius addresses this by design, not as an afterthought. Corepoint Signal Technology Every Delphius Speaker Cable is supplied with two Corepoint Signal units, one per channel. Each Corepoint connects to the ERS wire via spade connector and provides the electromagnetic reference that ERS requires to function correctly. The result is a cable architecture in which the signal path and its electromagnetic environment are managed together rather than treated as separate problems. The Corepoint units also make the Delphius an expandable platform. Each unit accepts an Entreq Max post (sold separately), allowing performance to be extended incrementally as your system develops. The Max range — Max T, Max S, Max Ti, Max Pa, Max Pl and the range-topping Max Supreme — gives you a meaningful upgrade path without replacing the cable itself. With two Corepoint units in a Delphius Speaker Cable, that opportunity is doubled. Construction The Delphius Speaker Cable is constructed entirely by hand at Entreq's facility in Sweden. It uses copper and silver conductors, a silver ERS wire and hook, cotton dielectric, and connectors customised to Entreq's exact specifications. Available with spade or banana plug terminations, both featuring custom connectors built to Entreq's specification. Standard length is 2.5m per channel; custom lengths are available on request through your Entreq dealer. Part of the Entreq System Delphius is at its best as part of a properly prepared system. Entreq grounding, Magneus at the entry points, and Protectus, Vibbeaters and MaxMix T2 shaping the electromagnetic field around your components all make the next step more effective. Used together as a coherent system, Entreq products allow your components to deliver everything they are capable of. The Delphius Speaker Cable is the point in that system where signal is most exposed — and where the architecture earns its place most plainly.

The Delphius Speaker Cable is for listeners who have invested seriously in their system and want their speaker cables to match that commitment. It suits those who have already addressed earlier points in the signal chain and are ready to treat the final, most exposed stage with the same rigour. It is not an entry-level purchase, and it is not for those who regard cables as an afterthought. For whom the last meaningful improvement to a well-assembled system is the only criterion, Delphius is worth serious consideration. Buying from Martins Hi-Fi Martins Hi-Fi has been in Norwich since 1968. Elizabeth Gould runs the business today, and we stock only brands we have heard properly and stand behind. We carry the full Entreq cable range in our Norwich showroom, and we would encourage you to hear the Delphius Speaker Cable as part of a complete system demonstration before committing — the difference the Entreq architecture makes is the sort of thing that is far easier to understand through listening than through reading. When you get in touch, you'll be speaking with Dave, Chris and Tim — experienced specialists who can advise on this product and your whole system.
