Tellurium Q and the phase distortion problem

Tellurium Q are unusual in two ways, and the second follows from the first.

The first is what they design for. Most cable makers describe their work in terms of conductor material and shielding. Tellurium Q describe theirs in terms of phase distortion: the tendency of a cable to smear the timing relationship between frequencies as the signal passes through it. Their position is that this is what listeners actually hear when they hear a cable, and that conductor exotica is a distraction from it.

The second is what they will not tell you. Tellurium Q publish almost nothing about construction, materials or geometry. They will not name a conductor metal. For some customers that is frustrating, the frustration is fair, and we would rather acknowledge it than talk around it. The company's answer is that construction detail invites people to judge a cable on paper instead of by listening.

What we can say from our own experience is that the range is unusually consistent in character from bottom to top, and that the differences between the ranges are easy to hear on a decent system.

Shop by Range

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.

    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.

    Tellurium Q Ultra Blue II UK to IEC Mains Cable

    SKU: TQ Ultra Blue II Mains

    (2 reviews)

    £403.33
    Ex. VAT

    Ultra Blue II looks pretty much exactly the same as the old Ultra Blue except for the “II” denoting the new generation cable. Plug in a burnt in Ultra Blue II after the old version and you will hear within seconds why we have upgraded this cable. The sound is fuller, more organic and better balanced in the whole range. The top end detail is still the same but everything else has risen to that performance level.

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.
