Tellurium Q Black Diamond Speaker Cable - Factory Terminated

 

The introduction of the Black Diamond Speaker Cable marks a significant achievement for Tellurium Q, building upon the foundations laid by previous ranges. While the now-discontinued Graphite cables were celebrated for their exceptional quality, certain systems did not fully synergise with them, resulting in a sound profile described by a few as overly rich and dense. This feedback ignited a quest for innovation at Tellurium Q, propelling them into extensive research and development.

In this journey, they experimented with novel material combinations, including a unique blend of Tellurium Copper for the connectors, to enhance universal compatibility without sacrificing the signature Tellurium Q sound. Although specific alterations remain under wraps, in line with their policy of maintaining secrecy about their design and manufacturing techniques (as detailed in our "Why No Tech Specs" document), the outcome was the Black Diamond Speaker Cable. Not only did it achieve a level of performance that set a new benchmark for Tellurium Q, but it also emerged as a more universally adaptable option.

The Black Diamond and the Graphite may share a visual resemblance, but the auditory experience they offer sets them worlds apart. The Black Diamond Speaker Cable not only surpasses the high bar set by the Graphite range but does so with a compatibility and performance that are nothing short of revolutionary. With great excitement, we introduce the Black Diamond as Tellurium Q's pinnacle achievement, already earning accolades that eclipse those of the Graphite cables. Experience the difference for yourself and understand why this product represents the zenith of Tellurium's endeavours.

Contact Enhancer Option

To ensure the best possible connection between your system, Future Shop recommends the DeoxIT Gold G-Series contact enhancer.

DeoxIT Gold is carefully applied to the plug contacts of your cable and is a unique conditioning solution designed to improve conductivity and provide long-lasting protection on gold, base metals and other precious metal contacts and connections. DeoxIT Gold penetrates plated surfaces, molecularly bonding to the base metals to seal and protect both surfaces.

The benefits of applying DeoxIT gold are:

  • Improved Conductivity
  • Maintained optimum signal quality
  • Reduced wear & abrasion
  • Prevents fretting/dendrite corrosion
  • Forms a protective anti-tarnishing coating
  • Stabilises connections between similar and dissimilar metals
  • Reduces arcing, RFI and intermittent connections

Please select this option from the above ‘Contact Enhancer’ drop-down menu and our engineers will apply the contact solution to your cable connectors prior to shipping.

“The obvious danger is that the ambitious audiophile will soon want to recable the entire system with Tellurium Q Black Diamond…..Such cables really are the stuff recommendations to close friends are made of”

Frank Hakopians

"In short, we face the best audio cables High End to be found in our country if we stick strictly to the quality/price. A real discovery"

Salvador Dangla - AV Premium

The Tellurium Q Black Diamond speaker cables' ability to retain drama and at the same time exhibit utmost transparency was demonstrated in a strikingly impressive manner. The xylophone sounds extended almost forever (so to speak) and were sharply projected on the virtual soundstage. It was exciting to “observe” (hear) tones forming in front of me with all the right natural colors/timbres and then slowly fading away. There was lots of air around the instruments and their separation was exemplary. The micro dynamic ability of the Tellurium Q Black Diamond speaker cables was breathtakingly good and great micro dynamic responsiveness is the main reason why some systems sound incredibly vivid and lifelike.”

"... reviewing the Tellurium Q Black Diamond speaker cable. Up to this point I had not found any cable over the last decade that had outperformed the Philosophy Cables loom that had been in situ. Until now. "

Tony Bolton - Opinion Column HiFi World 2015

"But perhaps their reticence is understandable when the product sounds as good as this – after all, why let others in on the secret? Used in a variety of systems the Black Diamonds consistently revealed a wider perceived bandwidth, bigger soundstage and the ability to present transient details in an effortless fashion"

HiFi World - Awards Edition Jan 2015

“My final thoughts are of complete admiration for the Tellurium Q black Diamond Speaker cables, they are incredible speaker cables, absolutely incredible. I am still stunned by how I was able to hear the deficiencies of my system, but once fixed the sound was elevated to a new height. This did not come easy, I was right about them in this regard but wrong about them for 99% of the time I spent with them. The last 1% of the time changed everything. I changed from being impressed to being in love and now I do not want to take them out of the system. When things click to this level then its kick back and listen time, then listen more and more with a big smile and some happy tears for good measure.”

About Tellurium Q Made in United Kingdom

Tellurium Q cables offer a unique approach to cable performance, focusing on minimising phase distortion, a common problem inherent in all cables. The Tellurium Q team understands that all signal path materials act as electronic filters, impacting the naturalness of vocals and overall audio quality.

Instead of ignoring this issue, Tellurium Q embraces it and engineers cables that provide a clear path for the signal, aiming for the most natural sound possible with current technology. Their construction involves multiple stranded conductors of varying materials, dielectric materials, and geometries. Every detail, from solder mixes to plating thicknesses, is carefully considered.

Tellurium Q has developed three distinct families of sound to cater to different customer preferences: the Tellurium Q Silver range offers silver-like characteristics without harshness, the Tellurium Q Black range (including the Tellurium Q Black Diamond) provides transparent and lifelike reproduction, and the Tellurium Q Blue range adds a slight warmth to balance brighter systems. Each range is designed to enhance the audio experience uniquely. They strive to offer a clear, transparent, and natural listening experience and invite customers to hear the exceptional results of their work for themselves.

Having entered the Hi-Fi scene in 2010, Tellurium Q has won several coveted awards and global recognition. With their extensive range of top-tier cables available in 37 countries, they've accumulated 154 exceptional reviews and 14 'Products of the Year' awards from international Hi-Fi magazines. They have twice received the 'Queen's Award for Enterprise' in recognition of their remarkable export growth. Tellurium Q's uncompromising commitment to excellence ensures its products are not just good or average but exceptional, offering customers the best available in its price range.

Free Premium Cable Burn-In Service: Experience the Power of Nordost VIDAR 2 Machine

 

We are thrilled to unveil our upgraded cable burn-in service, now featuring the cutting-edge VIDAR 2 burn-in machine. At Future Shop, we strive to provide the best possible experience for our customers, and this enhanced service is designed to unlock the true potential of your high-end cables. Read on to discover the exceptional benefits and advancements offered by the VIDAR 2 machine.

Please note: We are unable to burn-in cables with stripped bare ends or BFA plugs. Cable burn-in occurs after your order has been processed for the selected time period. For custom-length cables, burn-in takes place after termination by the manufacturer or our skilled engineers.

 

 

 

The Nordost VIDAR cable burn-in machine seamlessly combines three vital functions into a single operation:

  • Neutralising charges around cables and insulation: The VIDAR 2 effectively dissipates any built-up charges, creating an optimal environment for signal transmission.
  • Deep conditioning into the conductor core: With its wide band and profound conditioning capabilities, the machine induces significant changes in signal passage through the metal, resulting in enhanced performance.
  • Ultrasonic surface conditioning of conductors: The VIDAR 2 employs ultrasonic technology to refine the conductor surface, further refining the signal quality.

In addition to all the advantages of its predecessor, the VIDAR 2 introduces remarkable improvements, including:

  • Complex burn-in signal with wider bandwidth and richer content
  • Enhanced directionality for cables
  • FOUR burn-in zones - including a new digital zone for USB, Ethernet, and Coaxial (BNC) cables.

Using a proprietary blend of composite and complex signals, the VIDAR 2 ensures comprehensive cable conditioning. The signal consists of ultra-low and ultra-high frequencies, surpassing video frequency ranges. The signal effectively penetrates the core at ultra-low frequencies by oscillating throughout the cable while swiftly traversing the surface at ultra-high frequencies. This transmission methodology counters harmonics and heterodynes between the two complex waveforms, improving signal performance throughout all cable layers.

Furthermore, the circuitry design boasts a unique feature that drives electrons above the conductor into the dielectric or insulation area. This process neutralizes any electrical charges that may impact the signal integrity. With the Nordost VIDAR, we go beyond merely sending ping-pong signals along the cable; we also ensure a balanced signal flow from the centre core to the outer shield in interconnect cables.

 

What does all this mean for you?

Conditioning your cables with the Nordost VIDAR yields remarkable benefits, including enhanced sound staging, heightened detail reproduction, and a more captivating and musical presentation.

We offer our cable burn-in service as a complimentary offering at the discretion of Future Shop. While we strive to accommodate all burn-in requests for the specified time periods, please understand that during exceptionally busy periods, we may be unable to fulfill all demands due to the limited connections available on the Nordost VIDAR cable conditioning machines.

Tellurium Q just the best.

Verified Buyer
These are simply fantastic cables. I knew they would be good, but not to the magnitude that they have improved my system. If you have a price comparable system you don’t worry about paying the price they command.

Future shops service second to none as usual.

I upgraded from Ultra Black II to Black Diamond cables, and all I can say is WOW! It was like having a whole new system. I am just blown away.

I didn't expect that much difference at this level. It is worth every penny.

Read Chris's review below. I agree with every word.

Bringing the Magic
8 Jan 2022
Verified Buyer
I bought as an upgrade for the TQ Black ii speaker cable, and, at first, they sounded very, very similar, a little more open and “clean” sounding but otherwise underwhelming and a bit disappointing. Patience. The more I listened, the more I realised there was an engagement with the music that wasn’t there before. It’s tough to describe, but it’s no longer possible for my thoughts to wander, and literally, everything is exciting, interesting and moving. I can’t work or read with my music now as I can’t tear my mind away from the sound. There is genuine magic here. Yes, there is slightly more bass, the treble is crisper with a little sparkle, and the detail more apparent, but it’s all so musical and so well balanced it seems so subtle that I hardly notice. I can’t stop grinning. Amazingly for cables, these are now my favourite bit of the whole system.

I never thought I could love something more than the monoblocks, but here we are!!!
