Synergistic Research

Californian maker founded in 1992 by Ted Denney, working across cables, power, fuses and room acoustics. Synergistic take an unusually broad view of what affects a system, including the room itself.

A company that treats the room as part of the system

Synergistic Research cover more ground than most cable companies. Alongside cables and power products they make fuses, grounding systems, and the HFT range of High Frequency Transducers, small devices that address room acoustics without using conventional absorption panels.

The unifying idea is that a system is affected by more than the signal path: by the electrical environment, by the mechanical one, and by the room. Whether you accept all of that is a matter for your own listening, and Synergistic products vary in how readily they demonstrate themselves. The cables and power products are the most conventional part of the range and the easiest place to start.

Theodore Denney founded the company in 1992 and still leads the design work. It started in a 1,200 square foot industrial unit and now runs from a 13,000 square foot factory in Southern California, where the products are still built by hand.

The technologies are developed in-house. Active Shielding is the oldest and the most distinctive: a small power supply biases the cable's shield rather than leaving it passive, and the same principle drives the actively biased electromagnetic cells inside the PowerCell conditioners. Cables and outlets also receive a two-stage Quantum Tunneling treatment during manufacture. UEF, short for Uniform Energy Field, is the framework Denney uses to tie the range together.

The fuses have become one of the better-known parts of the line, with a colour-coded ladder running up through the range.

Foundation, Atmosphere, Galileo and SRX are the cable levels in ascending order. The fuses, PowerCell distributors and HFT room treatment products sit outside that ladder and work with any system.

    £41.62 £58.32
    Ex. VAT ✓ Save £16.70

    Synergistic Research Red Fuses employ a specially developed burn wire selected in blind listening tests for its ability to improve sound. Next they treat the fuse with a proprietary conditioning process followed by 1,000,000 volts of electricity in a process they call Quantum Tunneling that affects how electricity travels along the fuse for an unmistakable improvement in sound quality.

    £112.46 £158.33
    Ex. VAT ✓ Save £45.88

    The brand new Purple Fuse is Synergistic Research's latest flagship fuse, surpassing the performance of the remarkable Orange fuses thanks to a new, three-stage conditioning process and a new premium graphene UEF compound to reduce the noise floor further than has ever been possible for Synergistic Research fuses. Slow-blow fuses are most commonly found in high-powered electrical equipment. They are more tolerant to high current passing through, meaning the fuse will withstand sudden high current flowing through the unit. Slow-blow fuses should be used where the equipment utilises large amounts of power, especially when switched on, like power amplifiers, integrated amplifiers or headphone amps. When installing your new fuse, please ensure you test the fuse in both directions as they are directional from left to right. When the fuse is inserted in the correct direction it will sound more detailed.

    Please note: some configurations will be special-order.

Synergistic Research combines advanced materials, quantum technologies, and rigorous testing to deliver an audio experience that feels closer to live music. Their innovations in fuses, cables, and acoustic treatments set them apart from traditional hi-fi brands and are trusted by audiophiles worldwide.

The Master Fuse is Synergistic Research’s most advanced design, engineered for maximum resolution, dynamics, and soundstage depth. The Purple Fuse, while more affordable, offers excellent performance and long-lasting reliability. Both elevate your system, but the Master Fuse sets the highest benchmark in the range.

HFTs (High-Frequency Transducers) fine-tune a room’s acoustics at the micro level. When placed strategically around your system, they reduce harshness, improve imaging, and create a more natural, live-like soundstage.

Yes. Synergistic Research fuses (including the Master, Purple, Pink, Orange, and Blue) are directional. For best results, install them so electricity flows left to right when viewing the fuse label. Many listeners report subtle sonic differences when reversed, especially after the fuse has been broken in.
