Black Diamond Speaker Cable

Many years ago Tellurium Q produced a speaker cable called the Graphite. While sounding incredible in most systems and winning awards, there were a few that reported that they actually sounded “wrong”, a little thick and heavy. This only occurred on very few systems but gave us something new to launch into researching. (We love a challenge because no matter what else we always learn something new).

The Black Diamond speaker cable was born out of this work. The Graphite speaker cable was referred to as “the best speaker cables I’ve ever heard” by one reviewer but even so the Black Diamonds significantly out perform them without any of the apparent drawbacks of the old Graphite as you will see for yourself reading the reviews and hear for yourself when you plug them into your system.

Reviews and User Comments

Pursuit Perfect System

“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.”

Mono & Stereo

“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.”

HiFi World: Product of the Year 2014

“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”

“Their tonal balance is perfect.”

– Wojciech Pacula, High Fidelity.pl


Performance Profile

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.

Why Choose Tellurium Q

Tellurium Q is a British high-end cable manufacturer that has built a global reputation for producing cables designed around one core principle — preserving timing, coherence, and the natural structure of music. Rather than focusing purely on conductor materials or exaggerated “Hi-Fi effects”, Tellurium Q approaches cable design through extensive listening and phase-focused engineering, resulting in products that consistently improve musical flow, tonal balance, and system realism.

At HeyNow Hi-Fi, Tellurium Q has become one of the most successful and consistently recommended cable brands, particularly the highly regarded Black II series. One of the major strengths of the brand is how effectively the cables work together as complete looms throughout a system. Customers often begin with a single interconnect or speaker cable before progressively expanding through the range, discovering how consistency across the loom can significantly improve coherence, tonal balance, imaging, and overall musical flow.

The Black II range in particular has proven remarkably successful because it delivers genuine refinement and naturalness without pushing systems into sounding overly warm, bright, or analytical. As customers move further through the Tellurium Q range into Ultra Black and beyond, the presentation becomes increasingly open, dimensional, and revealing while still maintaining the musical ease and listening comfort the brand is known for. This scalability and system-wide synergy is one of the reasons Tellurium Q continues to receive worldwide industry recognition and strong long-term customer loyalty.

Signature Design and Sound

Manufactured in the United Kingdom, Tellurium Q products are developed using proprietary design methodologies centred around signal timing and phase behaviour. The company deliberately keeps many technical aspects confidential, preferring listeners to judge performance through listening rather than marketing specifications alone.

Sonically, Tellurium Q cables are known for their smoothness, coherence, and highly natural presentation. The sound feels organised and relaxed, with excellent tonal density and a remarkable ability to reduce glare and harshness without sacrificing detail retrieval or openness. Vocals become more believable and focused, instruments carry greater texture and separation, and the soundstage often feels deeper and more stable.

One of the defining strengths of Tellurium Q is the way complete looms allow systems to sound more unified and musically convincing. Rather than drawing attention to individual sonic traits, the cables work together to improve flow, timing, and realism across the entire presentation.

Tellurium Q Product Range

The Tellurium Q range includes speaker cables, RCA and XLR interconnects, digital cables, USB cables, Ethernet cables, and power cables across multiple performance tiers. Popular ranges including Black II, Ultra Black II, Silver, and Statement allow customers to progressively refine and scale system performance while maintaining consistency throughout the cable loom.

The Black II series remains one of the most respected and widely recommended ranges within high-end Hi-Fi thanks to its exceptional balance of musicality, refinement, and value. Higher-level ranges including Ultra Black and Silver introduce greater transparency, spatial realism, and low-level detail retrieval for customers seeking additional performance from increasingly capable systems.

For listeners seeking cable solutions that prioritise coherence, realism, and long-term listening satisfaction, Tellurium Q remains one of the most successful and musically rewarding cable brands in contemporary high-end audio.
