Tellurium Q Cables

Tellurium Q Cables

Designed around a single stated goal: reducing phase distortion. They publish almost nothing about construction and ask to be judged on listening instead, which customers consistently do in their favour.

Tellurium Q build every cable around a single argument: any material in the signal path acts as an electronic filter whether the designer intends it or not, so the job is to make that filter as close to neutral as possible. Geoff Merrigan founded the company on that principle, coming to it from industrial chemistry and materials science rather than from audio.

The specific target is relative transient phase distortion, the smearing of the leading and trailing edges of sounds. The reference point is Bell Labs research from 1930 into phase distortion in speech, which found that distorted speech carried audible artefacts that were extraneous to the speech and transient in character. Tellurium Q state their focus as the phase relationships in a system, and they ask to be judged on listening rather than on published figures.

Cables are made in the UK, and the company holds the Queen's Award for Enterprise, granted in 2018 and again in 2021. The upper ranges use the company's own tellurium copper connectors, the material Tellurium Q takes its name from.

The power cable range runs from the Blue and Black families, through the Silver ranges, to the Diamond and Statement cables at the top. Each step is intended to carry the same tonal character further rather than change it, so moving up the range sharpens what you already have rather than giving you a different sound.

Tellurium Q run three families rather than one ladder, and each has its own character. Start by choosing the family that suits your system, then the level within it. Every family climbs through three steps: the base range, the Ultra version, then the Diamond version. The families interleave by performance rather than stacking, so a Silver sits above a Black but below a Blue Diamond. Statement sits above all nine.

    While the “Black range” (Black, Ultra Black and Black Diamond) could be categorised as neutral/ natural the “Silver” would lean more to neutral, detail and extension. The Silver performance sits beyond Black for very good reasons that you will hear.

    Tellurium Q Ultra Black II XLR Balanced Interconnect Pair

    SKU: TQ Ultra Black II XLR

    (18 reviews)
    From
    £570.00
    Ex. VAT

    These are a significant step up from the old Ultra Black XLRs (as you would expect from any of tellurium Q's developments by now). What they found in their listening tests is that the Ultra Black II's are smoother, more accurate and more detailed with more depth / 3 dimensionality. Built to complement the astounding Ultra Black II speaker cable but also stands alone with its performance profile.

    Even taking in account all the awards that the old Ultra Black speaker cable won, this new version gives a whole new level of performance that is obvious from the first second of listening. Greater detail, more clarity, more organic but still sitting very firmly in the Black cable family.

Tellurium Q treats each cable as a vital part of your hi-fi system, engineered to minimise phase distortion, a subtle but important factor in accurate sound reproduction. In our experience, this design approach gives music more clarity, detail, and a natural sense of timing, delivering an improvement you can hear from the first listen.

Yes. Both in our own testing and from feedback we’ve received from many customers, Tellurium Q speaker and interconnect cables tend to open up with extended use. After a period of running-in, the sound can become smoother, more cohesive, and more engaging, with instruments and vocals gaining extra refinement.

This depends on your system’s character and your personal preferences. The Blue Range adds warmth to brighter setups, the Black Range offers a natural, transparent sound that suits most systems, the Silver Range provides high detail and openness without sharpness, and the Statement Range delivers the ultimate in clarity, dynamics, and realism for reference-level performance.

Tellurium Q cables are built to last, but we recommend handling them with care to maintain performance. Avoid tight bends, excessive pulling, or exposing them to extreme heat or moisture. Always hold the connectors rather than the cable body when plugging or unplugging.

Tellurium Q speaker cables are highly regarded for their focus on timing, coherence, and natural presentation rather than emphasising specific frequencies.

Yes, they are directional and should be installed according to the markings on the cable jacket from your amp to your speakers.

They work well across many systems, but higher-level cables tend to shine most in revealing setups.
