Did you ever expect a new cable to make such a bold claim?

Given the conservative look of the Tellurium Q cable compared to our usual "High-End" and well respected reference cable I wasn't expecting to be impressed, but within seconds I could hear that this cable is indeed something special! The timbre of instruments and voices sounded more natural and imaging was significantly improved. Without question, this cable is going to make many audio enthusiasts very happy indeed".
Alan O'Rourke (Managing Director, Ruark Acoustics & Vita Audio) (

"As a producer I have heard a large range of speaker cable and there is nothing I have heard that compares to this product, period."
Simon Lomax (

Tellurium Black was our first cable and we knew we were on to something special when we took the prototypes to various dealers for their comments and input. One in particular would not believe that it could match his somewhat thicker more expensive cable that was in his demonstration system.

We sat down and listened to some of his familiar music tracks. Then we swapped the cable for Tellurium Black. He sat forward, looked at us and quite seriously asked what else we had done to his system while we were changing the cables over. It was only when he swapped the cables himself a couple of times did he believe the evidence of his ears. He also stocked the Tellurium Black.

It is thin and it is small. By conventional thought it should not be able to do what it does and as well as it does it. That is why we have applied for a patent for one of the aspects that allows these cables to perform so well.

  Audio products designed to combat phase distortion

Tellurium Q presentazione UK Designed Audio Cable - UK Manufactured Audio Cable

10 products of the year and most wanted component in just 2 years by preserving relative phase relationships in a signal.

The first cables designed primarily to combat phase distortion.

Our work is for the audiophile and music lover who wants to hear the clearest, purest sound from their system at a reasonable price.

We are focused on performance and our aim is to set a new standard.

“something that I’ve never heard from any cable at this price point.”
Paul Rigby HiFi World August 2010

“Cavernous acoustic space.....palpable sense of reality...good sense of timing and pitch...the sound was controlled and didn’t harden as the volume increased...even tonal balance.”
Hi Fi News (Feb 2010 edition)

What you don’t get from us:
Pretty expensive packaging and superfluous ornamentation on the products that add nothing to the objective of the best sound with the least phase distortion possible.

What you get from us:
The best performance for price that we can give you.
A minimal amount of packaging (recyclable) because products shouldn’t cost the earth.

Tellurium Q at a glance

Tellurium Q is primarily an audio research and development (R&D) company that also manufactures products. R & D is at the centre of every decision we take and every product we make.

That is why we design and develop products starting with a completely blank canvas and ask “what is really happening with this process, in these materials” and build on solid fundamentals. That is why you may find that what we produce might look a little different from what you might expect but that is just because we are focused on how to get a better clearer sound. How something looks is of secondary importance because we are working for the serious audiophile and music lover who, like us,wants to hear more in their music. That may be the reason that although our little company has only just appeared on the HiFi scene has immediately been awarded 5 Globes for an entire speaker cable range, awarded cables of the year for the ENTIRE cable range by HiFi Plus magazine and again product of the year by HIFi World in their Jan 2011 edition. All in the first 12 months!

Tellurium Q® : The Range

Although cables should not affect the sound there are factors that have to be considered because audio systems are not perfect and customers have listening preferences too. So you will see we have engineered three distinct families of sound to take account of three distinct demands our customers have asked for. Which is why we have the Silver and Blue ranges as well as the Black which help achieve this for our customers:
Silver range: The sound can best be described as silver but without the fatigue and harshness that can go along with that material.
Black range: the natural / transparent range that allows an incredibly life like reproduction for use in a well balance system to simply unlock what the system can do.
Blue range: slight warmth that just takes the harsh top edge out of a system that is a little brittle or bright.
So now you know why our cables have won so many awards and we have grown so quickly. We have taken a different and radical approach by looking at the “problem” of cables because they are “secret electronic filters” and you ignore that at your listening peril.
By thinking of cables in this way we can get closer to our goal of combating phase distortion (or more accurately, preserving relative phase relationships in a signal) giving you the most transparent, natural sound possible.You can think of it like a blurred picture becoming clear.

Tellurium Q® : Our Focus

Tellurium Q® have been asked many times why our cables perform differently to others. We are not going to pass on the exact details of what we are doing to achieve the performance that the reviews and multiple product of the year awards talk about, however time moves on and so it is time to talk a little more about the how.
When Tellurium Q® was set up the focus was primarily on phase distortion and minimising this problem inherent in all cabling, whoever makes them and where ever and however they are made. The reason it is a problem is simple, all materials (not just cables) in the path of a signal will act as an electronic filter according to the definition in the box below, whether you want it to or not. This is undeniable.
Please understand we use the word filter as its scientific definition and not necessarily as something being “filtered out” like with a mechanical sieve. We are primarily focussed on removing the smearing of frequencies through a timing shift and by doing this you get better clarity and transparency from Tellurium Q® cables.
This is the definition of an electronic filter:
“A filter is an electrical network that alters the amplitude and/or phase characteristics of a signal with respect to frequency. Ideally, a filter will not add new frequencies to the input signal, nor will it change the component frequencies of that signal, but it will change the relative amplitudes of the various frequency components and/or their phase relationships.”
Source: National Semiconductor Corporation
N.B. This is true of all speakers, amplifiers, DACs, CD players, cables etc…in fact anything in the signal path.
Once you accept the fact that your audio system is acting as multiple electronic filters smudging your music, then you have a choice:
a. Forget the cable is an electronic filter (completely in the face of science) and compromise by having a smeared sound or
b. Do something about it and engineer as clear and phase neutral a path for the signal as possible to get the most transparent sound that current technology will allow and preserve the original signal phase relations as much as possible.
Unfortunately it is not as easy as just looking at a chart of materials and simply picking the one with the best conductivity. If that were the case then you would put some silver wire in place and the job would be done.

Where Tellurium Q® Came From

People have been asking how Tellurium Q® came about and what we are doing to make our products work so differently from what is currently available. This has caused us problems because there are trade secrets and production methodologies that we definitely do not want to share with our competitors. I think that sometimes we are too much on the side of caution and that causes reviewers and our distributors a little problem. What do they say? What is the story to give our customers, a hook, a reason to listen when there are so many companies claiming big things? Why should people believe that we have a genuinely different approach? Yes a client can hear this is true within seconds of listening but the big problem is giving people a reason to want to listen having not yet heard the cable. In the UK this is not such a big problem as more and more people are giving their feedback to their friends and Tellurium Q® is spreading rapidly by word of mouth as much as from the remarkable reviews.
However we can say a little about our background, how Tellurium Q® came about and what we had to do to develop the products. So here goes.

How Tellurium Q® was born

One afternoon at a recording studio in Somerset, Geoff Merrigan, who was there because he was the studio’s business advisor started a conversation with the studio owner and a technical electronics expert. As there was a strong interest in science and technology they started talking about the system set up and sound quality relating to, and influenced by the various electronics. There was a bold claim that the cables were causing problems in recording quality. Both the studio owner and Geoff took the stand point that a cable is just a cable and all it needs to do is transmit a signal and enough power, end of story, surely? An hour later after discussing the fundamentals of signal transfer theoretically in a standard cable’s construction and why exactly that caused problems. It made absolute sense and Tellurium Q® was born on a leap of faith. The new company invested heavily in R&D and non-standard tooling to bring about the first cable, Tellurium Q Black. Thankfully it exceeded expectations and in the UK there was an immediate uptake with a small handful of dealers who were prepared to use their ears. The most recent phase of development sees the introduction of our own tellurium copper connectors that have a near perfect synergy with the Tellurium Q® cables, as the latest review in the magazine HiFi World confirms. See here for review.
What people do not realise is that to get the best performance in a cable you actually have to be prepared to compromise between a number of factors. For example in most applications a signal must not leak into the dielectric (but this is a good thing in capacitors).
Stepping back further, you even need to ask what exactly is a “signal”. An electric current is not a bunch of electrons entering a wire at one end, zipping through and popping out the other end. No. It is more like the Newton’s cradle toy where a wave of impacts go through the swinging balls quickly while the balls themselves move very little. Even this analogy is a world away from what actually happens, though. Of course the electrons work their way through the wire. Just not very quickly that is all.
When you understand what a signal actually may be and can model the way it is likely to behave and how this “wave potential” is affected and then what function that signal has to fulfil, it is then time to do a bit of a balancing act. This is between, for example, capacitance, inductance, accurate transmission (not just material “purity” as many think) and high speed transmission (which in itself involves a whole host of lesser criteria). It is this fine tuning process that can lead to some surprises in choice of materials that is REQUIRED for the compromises to work efficiently and effectively. What we do a little differently is that we skew the balancing act to take into account phase accuracy to give a recording correct timing reproduction. In a nutshell, that is how we at Tellurium Q®get the results we get. We believe that we put more into research and development than any other company as a percentage of our profitability and we have no reason to stop doing so. Research is our passion and our customers are the beneficiaries of this.

Tellurium Q Black 2m

Ottima assistenza da parte di Playstereo: sostituito cavo difettoso in tempi record senza aspettare la riconsegna.
Per quanto riguarda il cavo sono molto soddisfatto perchè finalmente ho trovato l'equilibrio che cercavo...

Innanzitutto 5 stelle a Playstereo per i velocissimi tempi di consegna.
Per quanto riguarda i cavi di potenza Tellurium q BLack devo dire che mi ha colpito molto la naturalezza su tutte le frequenze, la gamma media è ben presente e il basso è realistico.
Un grosso punto a favore è quello dell'ergonomia: questi cavi sono facili da sistemare con una guaina piatta e non rigida e sono poco ingombranti al confronto di altri cavi di potenza.

Tellurium Q Black: inaspettato!

Ho avuto diversi cavi di potenza.
Agli albori della mia passione iniziai con discreti cavi ma, man mano, le esperienze mi hanno portato ad upgradarli seguendo una escalation, fino ad avere cavi abbastanza costosi.
Il punto di svolta, però, è stato fissato da questi Tellurium Q Black.
L'aspetto fin troppo semplicistico mi.ha incuriosito, e le diverse recensioni positive mi convinsero ad acquistarli, e ora sono in pianta stabile sul mio impianto.
Il perché è semplice: sono di una naturalezza disarmante, pur mantenendo una delicata nota di calore, un grande dettaglio, ottime voci e un basso supremo.
Ho smesso di cercare cavi di potenza.

Ho sempre messo in discussione l'utilizzo di cavi costosi all'interno del proprio impianto avendo utilizzato per anni cavi di potenza economci anche con apparecchiature di buona qualità ma poi sono arrivati questi meravigliosi cavi, sottili comodi pratici e dal suono stupefacente con un'incredibile musicalità, dinamica, dettaglio e trasparenza ma senza mai sbilancianciarsi troppo in nessuna gamma di frequenza risultando quindi cavi equilibratissimi.Sono contentissimo di aver migliorato notevolmente il mio impianto e ringrazio infinitamente playstereo per aver consigliogliato questo prodotto.

Confermo le recensioni precedenti.
Il rapporto qualita/prezzo e' veramente notevole.
Da abbinare ad il suo equivalente di segnale.
L'accoppiata cambia il volto all'impianto contenendo la spesa.
Neutralita' (e non solo) a prezzi umani.

Congratulazioni a per la disponibilità e la professionalità prestata.

Attualmente uno dei migliori cavi di potenza sul mercato.
Ne ho provati diversi, molto più costosi, non aventi le stesse "caratteristiche sonore"

Ottimo prodotto!
Lo consiglio a tutti gli appassionati di musica. 10+

Wow, ottimo come sempre il servizio playstereo.
Il prodotto mi liscia addirittura senza fiato per la categoria di prezzo al quale appartiene, trasparenza, messa a fuoco e tridimensionalità sono caratteristiche che esigo da un cavo comunque da circa 200€ ma la parte sconcertante é stato sentire corretti alcuni difetti di timbrica tipo perdita di controllo in gamma bassa e sibillanti in quella opposta. Il cavo ha dato questi benefici credo portando avanti la gamma media come un diffusore monitor da studio che come si dice sono sempre molto musicali.
Passando da un cavo semplice ad uno come questo credo che le differenze siano sconcertanti ma anche nel caso in cui come me passiate da un cavo della stessa categoria di prezzo le differenze siano udibili.
Tra TCI phiton , Van den hul Magnum e tellurium Q black chiunque sceglierebbe il terzo.
Saluti Davide Persechino

Oramai sono passati quasi tre mesi da quando ho ordinato questi cavi, solitamente non compro a scatola "chiusa" , ma vista l'opportunita della prova per 30 gg. ho ceduto alla curiosità; da subito ho appurato una qualità fuori dall'ordinario , ma anche questo prodotto non esula a mio avviso dalla sinergia con le altre componenti l'impianto. Importantissimo ( come consigliato da P. stereo) 200 ore di rodaggio , sciolgono le asprezze ( pur lievi ) esistenti , portando la fluidità del suono ad un livello realmente " neutro " , ma dove le sonorità assumono una pienezza di informazioni , a mio avviso difficili da riscontrare a questi costi, la tridimensionalità e per me la reale sorpresa di questi cavi , ben estesa sia in profondità che in ampiezza, con una predisposizione sulle medie di altissimo livello; chissà .. i modelli superiori ? spero possa essere utile il mio commento e buon ascolto a tutti.

Complimenti a Pl. St. rapidissimi , ottimo prodotto notevole la tridimensionalità , il timbro assolutamente naturale, piuttosto trasparente. Quando avrò approfondito meglio la conoscienza vi darò la mia impressione finale. Complimenti ancora.
