Mark of Authenticity
Printing crisp foil text directly onto flexible insulation is incredibly difficult—it requires specialised machinery and gives rise to inconsistencies. So why go to those extra lengths? The difficulties in manufacturing also make the cables much harder to counterfeit which assures our clients that these are genuine Tellurium Q® high performing cables.

Ultra Black II Speaker Cable

Ultra Black II
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.

The first few people to have heard the new cable were surprised to say the least.

Old Ultra Black
“Tellurium Q Ultra Black is the cable we wanted to make from day one. We told our UK distributor what to expect as we handed them a prototype that looked more like a fireman’s hose and less like a sonic phenomena. They glanced at the heavy, stiff and it has to be said ugly brown experiment. “Yes, well we will give it a go and take it to a few dealers to see what they think”. Later that day we get a phone call from our disbelieving UK distributors at Kog Audio, “what the hell is in it? We’ve never heard anything like this!”.

They took it on trust that the production version would be incredibly thin and flexible by comparison and look a whole lot better. So Kog Audio put in an advance order that day without needing to see or hear the production model because, in their words, “if it is even quarter as good as the prototype it will blow people away”.

We think that the production version sounds better than the prototype.

At first glance you could be forgiven for thinking that the Blue Diamond and Ultra Black were the same cable with different printing but when you plug the Ultra Black into your system there is absolutely no doubt that the Ultra Black is in a totally different league.”

Blue Family

Warm and forgiving for systems with a slight edge or for those who like a more smooth laid back presentation. Blue and Ultra Blue are especially good for AV and home cinema.

Black Family

Smooth, fine detailed and great resolution while actually reducing apparent harshness. Music is presented as a coherent, organic whole, with a jaw-dropping sense of realism and naturalness.

Silver Family

Totally uncoloured, acting as a wide open channel sounding unforced, vivid and dynamic with phenomenal resolution, transparency and natural tonal colours. All this while sounding extremely analog and coherent, from the exceptional top end extension to bottom with finely detailed, separated bass notes.

Reviews and User Comments

“I wanted to check if it’s possible to change the name of “Ultra Black” cables to “Ultra Awesome” please I couldn’t resist passing on my heartfelt appreciation to you and your team I have never listened to Leonard Cohen and Floyd this much before !”

“I would like to write to you to express my sincere gratitude for what your cables have done in my system.

Over time, I have installed Tellurium Q cables step by step throughout the whole chain of my equipment, and each of them has contributed something important. What began as a promising improvement gradually became something much more profound: a transformation of the entire musical presentation.

Thanks to your cables, I have finally been able to achieve in my digital system something I had long considered almost unattainable: a degree of realism, temporal continuity and musical flow that I had previously associated only with vinyl. For the first time in my life, my digital front end sounds truly believable to me, not only in terms of definition or scale, but also in terms of intimacy, coherence and naturalness.

What has impressed me most is that this was not a superficial change. It was structural. The piano changed, the orchestra changed, and above all the coherence of the sound changed. The music now flows in a way that feels natural and convincing, with a continuity that reminds me of vinyl, yet without losing the spaciousness and black background that good digital reproduction can offer.

This had been a long-standing hope of mine, one that I had almost given up on. I had reached a point where I no longer believed that digital sound could fully convince me in this way. Your cables helped me cross that final boundary.

I must also say that I never suspected phase distortion could be so relevant. Only now, after hearing the cumulative effect of addressing it throughout the entire signal path, do I understand how fundamental it is to musical realism.

So I simply wanted to thank you. Your work has allowed me to discover a level of digital playback I had never experienced before.

With gratitude and admiration.”

“he cables of the English brand TelluriumQ offer solid production quality and sound standards for a reasonable price. The Ultra Black II series cables keep up with the more expensive [deleted].”

“Vocals and music are in three dimensions that frees speakers and leaves only sound, mood and atmosphere. The speakers disappeared.”

“I wanted to say that the cables did arrive in good time and I was able to register them with the clever bar code system that you have. Beyond that I also want to thank you for creating such a wonderful gift to the audio enthusiast world ! I’m not sure if your life is filled with putting out fires or if you have floods of emails with praise . I Googled your name and I see you have a lot to do with these cables I just purchased. An English friend introduced me to them and while looking at the Black II I saw the Ultra for a decent price and the size I needed ( 2.5 m). I must say I was a little bit reluctant when I read about the 50 to 100 hours of break in time. To avoid disappointment I set my expectations low; telling myself ok you may not hear a big difference but it’s coming ! I was so impressed with the sound right out of the box . I’d never heard that speaker leads can open up a sound stage but I craned my neck turning to look down the hall looking for a new instrument being played with Peter Gabriel’s song ” Red Rain” .”

“Thought I would drop you a little follow up… I have really been enjoying the Ultra Black ii rca cables… For me they have been an eye (ear) opener to what good cables can do!

I have since acquired a pair of Ultra Black ii speaker cables… again wow! These are a great step on from the [removed] I was previously using.

I have not heard my system sound so refined yet full of detail… and feel… I find myself being drawn into the music much more easily.”

“It does not appear to be very difficult when hitting the high range, and the overall tight-knit part produces a very high level of playback sound. The sound of the analog feel is definitely full of charm.”

– Jonghak Lee, HiFi Club

“Having inaugurated an awards season for 2022, it seemed appropriate to acknowledge some key pieces of HiFi equipment that have passed through HF&MS over the preceding nine years. There have been just three ‘Night and Day’ moments over this period. These experiences are usually unexpected and simply tangible, where you just think; ‘blimey, this is really really good!

I was one of those who appreciated cables were important but I had no idea how profound the introduction of a medium to high-end cable could be and the Ultra Black II is by no means Tellurium Q’s best cable.”

– Simon Wilce, HiFi & Music Source

“The Ultra Black II speaker cable is good for systems where you need to improve spatial clarity. The images keep their density and their weight, the imaginary contours of virtual sources are better outlined and detailed separation of foregrounds appears. The same effect of underlined three-dimensionality of the front edge of the scene, and even with some expansion of the stereo base.

Things that for the same money help to jump into another level, are really rare.”

“It is hard to understand what has happened here, the last few weeks of exposure to Tellurium Q have changed my perception of HiFi and what can be achieved.”

– Simon Wilce HiFi and Music source

“It is this further extension of flesh-and-blood tangibility to vocals, guitar/bass fretwork, timbral colour and dynamic inference offered by the Ultra Black II which sets it apart from its brethren; it simply helped put performers in the room.”

“To be honest, sometimes I do struggle to hear meaningful differences between one brand and another or one model and another within a manufacturer’s offerings. However, I was genuinely taken aback when I first installed the Tellurium Q Ultra Black II speaker cables.”
