Entreq Delphius Digital Signal Cables Digital signal is often assumed to be robust — ones and zeros, immune to the kind of interference that troubles analogue. In practice, the high-frequency square waves that carry digital audio are acutely sensitive to their electromagnetic environment. Timing precision, signal integrity, and the noise that travels alongside the bitstream all directly shape what your DAC, streamer or processor receives. The Delphius Digital Signal Cable is Entreq's answer to that problem, and it is the first product in the company's new cable architecture. Energy Reference System and Corepoint Technology At the core of every Delphius Digital Signal Cable is Entreq's Energy Reference System (ERS) — a separately shielded reference wire that works in concert with the Corepoint Signal unit supplied with every cable. Where a conventional drain wire simply carries induced noise away, ERS interacts with the electromagnetic field around the cable itself. The Corepoint provides the stable reference point that allows it to do so. The result is digital signal delivered with the coherence and stability the format depends on — cleaner, more precise, and free of the high-frequency noise that compromises detail and timing further down the chain. Hand-Built in Sweden Every Delphius Digital Signal Cable is constructed entirely by hand at Entreq's facility in Sweden. Materials are chosen with purpose: copper and silver conductors, a silver ERS wire and hook, cotton dielectric, and connectors customised to Entreq's exact specifications. Nothing is off-the-shelf. The Corepoint Signal unit connects to the ERS wire via spade connector and ships with every cable as standard. Configurations Delphius Digital Signal is available in four formats to cover every common digital connection in a high-end system: USB — for connections between streamers, computers and USB DACs RJ45 Network — for Ethernet connections between network components RCA — for coaxial S/PDIF digital connections XLR — for AES/EBU balanced digital connections Standard length is 1.1m across all four formats. Custom lengths are available on request — speak to us directly and we will advise on what suits your system. Expandable with Max Posts Every Corepoint unit supplied with a Delphius cable can be taken further with the addition of an Entreq Max post, sold separately. The Max range — including the Entreq Max T — allows the performance of the cable to be extended incrementally as your system and ambitions develop. Your investment in Delphius is not a fixed decision; it is the start of an architecture that grows with you. Part of the Entreq System Delphius performs at its best as part of a properly prepared system. Entreq grounding via the Entreq Pluton or Entreq Olympus Hero, combined with Entreq Protectus and Entreq Vibbeaters shaping the field around your components, all make each subsequent step more effective. Used together as a coherent system, Entreq products allow your components to deliver everything they are capable of.

The Delphius Digital Signal Cable is for the listener who has invested seriously in their source and DAC and wants the connection between them to be equal to the components it joins. If you are streaming via Ethernet, running USB from a server to a DAC, or using S/PDIF or AES/EBU between digital components, Delphius addresses the part of the signal path that is most often overlooked. It is not a cable for someone just starting out — it is for someone who already knows what their system is capable of and wants to remove the last obstacles in the digital chain. 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 range at our Norwich showroom, and we are happy to demonstrate how Delphius cables perform within a complete Entreq system — including grounding, field management and equipment support — so you can hear the difference for yourself before committing. 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. Contact us at [email protected], call 01603 627010, or WhatsApp on 07554 687137. You can read more about how we work on our Why Martins Hi-Fi page. We are at 85–91 Ber Street, Norwich, NR1 3EY.
