Black Diamond XLR Cable

The Black Diamond XLR are Tellurium Q in a cable. The Black Diamond XLR uses our own TeCu connector and is the most natural sounding cable in the range, which is saying something.

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

“the cables ‘shimmer’ in all the right ways; the rolling off of a reverb tail is rendered perfectly…voices are expressive and natural”

– HiFi Plus, Issue 237

“Everything that is good about your system is left alone to shine.”

– HiFi Plus, Issue 225

“Black balances being neutral and transparent enough to bring out the best in middleweight audio, but not so open or shut in as to highlight its shortcomings or limit its potential to fly. It doesn’t matter why Black II works, what’s important is that it does. “It’s a cable to enjoy music by”

– HiFi Plus, Issue 204

“Two further swaps between the two sets of cables and I had heard enough to know that once again Tellurium Q had delivered on their stated intention, to take the good things about the Silver IIs and make them even better…

I know it is still only April, but I think I have just found one of my Products Of The Year: Bravo Geoff, mission accomplished.”

– Jason Kennedy, The Ear

“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.”

“The Silver III is leaving quite an impression here! Compared to the Silver II it is noticeably more nuanced and resolving, conveys space and separation more convincingly plus at the same time wonderfully smooth with a superbly weighted midrange. Wonderful!”

– Ray Ng, Raindrop Audio Singapore

+

“My initial impressions were rather shocking……

Firstly, reflecting upon my [other brand] cable comparison, who would have thought that I’d be describing the Silver IIIs as great value for money? That was a surprise. I was also surprised at the reduction of noise across the soundstage, the enhanced detail related to that and the extra focus produced alongside.”

– Paul Rigby, The Audiophile Man

“Geoff wasn’t really expecting to get any commercial success from the onset of developing the Silver III. He and his team used it just as a challenging project to find out what else they could learn about signal propagation. What they have achieved with the Silver III is something quite extraordinary. A very detailed and wide soundstage capturing all frequencies evenly, and with fast transients to give the music the bite it deserves
They bring the highest level of the TQ 3×3 matrix to those with the smallest pockets.”

– Janine Elliot, HiFi Pig

“When you are used to Silver Diamond and Statement it’s difficult to go back to Blue, but I did it last weekend. Installed the Blue and reproduced the cut number 3 from Tellurium Q CD. Then played Take Five, You Look Good to me (Oscar Peterson Trio) and “Ah! mes amis, quel jour de fête!” from Juan Diego Flores Ultimate Collection. This was repeated with Blue II and EVERYTHING was clearly better. I wasn’t surprised as already experienced this with Silver to Silver II, but this doesn’t mean that the improvement wasn’t surprising… It’s just that Tellurium Q users are getting accustomed to this kind of performance. An incredible QCR!”

– Francisco Moya, Spain

“In addition to pure expression without additives, it can also vividly reproduce the live atmosphere recorded in the Santuario de la Bien Aparecida church in Cantabria, Spain in 1987, with a three-dimensional sense of space.”

“The resulting high density is rich and three dimensional…..the Statement power cord gives a feeling of releasing the “seal”, the low frequency is more natural and there is a very natural extension, the energy is endless which is really impressive.”

– Super AV H23

“We have had nothing but fantastic luck with every Tellurium Q Product we have used…
…. Tellurium Q stuff is the real deal, and their power cord has the same effect as their signal cable.”
