Tellurium Blue Diamond (formerly known as Green) is the companion cable to Tellurium Ultra Black and is probably more suitable for slightly bright systems as they have a very slight “mellowing” effect. This can be particularly beneficial with class D and T amplifiers.
This cable has been significantly improved from its original well reviewed green jacketed version. The original green jacketed design had a ridiculously long burn in time before it showed its silky best and displayed what it could do. Often its “un burnt in” performance was so far from what the fully burnt in version was capable of that it was like two different cables.
We redesigned the cable to keep its top performance but slash the burn in time and as a consequence its overall performance has improved too.
“The Blue Diamond′s refinement addressed vocal clarity, projection and body impressively. Decay of strings and timbre of the acoustic guitar led into spatial awareness including crowd interaction and theatre perspectives. Yet what I found really intriguing was how the clever top end functioned….The point is that the Blue Diamonds relished those fast transients and delivered them with realism and sure-footedness, with that anticipated sharp “crack” delivered rather impressively, equally so with deep articulate bass laden with well defined and executed timbres and textures ..”
− HiFi Pig, 2014
“The Green cables could be described as ‘sweet′. That doesn′t mean cloying or that they throw any sort of veil over detail, far from it. These, warm, very friendly cables broaden the sound stage and provide, for the first time, an onion skin array of musical detail. That is, bass exhibited a multi-tonal depth and vocals displayed a complexity unheard by both the Blue and Black cables. …ideal for any slightly bright system”.
− Paul Rigby, HiFi World, 2010
“.. The green is a significant step ahead of most cables at the price in terms of communicating those nebulous qualities we think of as musicality and performance…”

|Specificatii||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.
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® : 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.”

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.
Relative conductivities of various metals assuming copper to be 100%
Some time ago we had some pure silver connectors manufactured and like all our developments tested them in a double blind situation. These we put against silver plated connectors using various base metal mixes and various thicknesses of plating. The pure silver performed worse than a plated connector with a “certain” thickness of plating. It was sluggish and almost muffled by comparison.
The more you focus on the fact that you are working with an electronic filter, then the easier it becomes to craft a much more transparent and natural sounding cable engineering each part of the signal path to minimise distortion. But there is a huge downside to this as every little detail of the constituents used and construction has to be tested in multiple configurations….and of course listened to.
The cable construction becomes more complex, using multiple stranded conductors of slightly differing materials and various dielectric materials and geometries. We have to pay attention to every part of each of our processes, even using non-industry standard solder mixes that varied between cables. Raw ingredients for the construction are highly specified as are plating thicknesses, even down to specifying what chemicals should or should not be included in a plating bath.
Let us give you an example of what we are talking about. These two plated finishes (both silver plating) conduct differently to one another.
The shiny finish is less conductive because of the additives used for that finish when plated. However that is not a great issue when you take into account the material underneath, cable construction and any other plated layers − we still end up with a very transparent cable assembly. It is all a very carefully balanced set of ingredients that become more than the sum of their parts.
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.
We would like you to have the most clear, transparent and natural listening experience and so hope that you get the opportunity to hear the results of our work for yourself.

Povestea incepe intr-o dupa-amiaza, intr-un studiou de inregistrari din Somerset. Geoff Merrigam, pe atunci consilierul de afaceri al patronului respectivului studiou, Simon Lomax (expert in electronica, muzician si maniac al sunetului) statea de vorba cu clientul sau. Cum ambii erau foarte pasionati de sunet, tehnologie si interrelationarea celor doua, discutiile au ajuns inevitabil la cat de mult are de suferit calitatea unei imprimari din cauza cablurilor. De aici si pana la ideea de a porni o afacere cu aceasta tematica n-a mai fost decat un pas. Concluziile lor? Cablurile trebuie sa faca bine o singura treaba - sa transporte semnalul cat mai curat si cu destula putere. Au disecat teoria transmiterii semnalului printr-un cablu si au incercat sa identifice ce anume ar putea cauza problemele de transmitere, iar in foarte scurt timp Tellurium Q Black aparea pe piata si incepea sa faca furori printre dealerii care aveau disponibilitatea sa-si puna putin urechile la treaba. Mai departe, traseul a fost simplu - dealerii au fost incantati, si-au convins clientii sa le cumpere, iar feedback-ul exceptional al acestora a determinat jurnalistii de la marile publicatii de profil sa le ia in teste. Reactiile acestora au fost atat de elogioase, incat marca a devenit, aproape peste noapte, o adevarata vedeta industriei.
Compania s-a dezvolat rapid, cele mai multe investitii mergand catre departamentul de cercetare-dezvoltare. Focusul creatorilor Tellurium Q a fost dintotdeauna incercarea de reducere la minim a distorsiunilor de faza, una dintre problemele eterne si intrinsece ale cablurilor electrice. Si le-a iesit din plin! Avand in spate specialisti foarte creativi si mai ales dotati cu urechi extrem de bune, Tellurium Q a reusit sa se impuna rapid in Marea Britanie si mai apoi la nivel global. Asa cum era de asteptat, premiile si recenziile elogioase nu au intarziat sa apara - nu mai putin de 10 premii de produs al anului si most wanted components in doar 2 ani de existenta! - astfel ca marca Tellurium Q a ajuns sa fie sinonima cu excelenta absoluta si unul dintre brandurile etalon in lume in materie de cabluri audio la aceasta ora (fie ca e vorba despre cabluri de alimentare, de boxe sau interconecturi). Totul a plecat de la o filozofie de afacere simpla, dar eficienta - fiecare produs nou trebuie sa aduca o imbunatatire audibila evidenta fata de precedentul.
