Product Description

Tellurium Q Black Diamond Speaker Cable - Factory Terminated

While the Graphites sound incredible in most systems 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. (They love a challenge because no matter what else they always learn something new).

During their research they played with a few new material mixes (one being a specific mix of Tellurium Copper for the connectors). Other things we altered …… well they are known for not commenting on the construction, materials and manufacture processes (see our pdf, "Why No Tech Specs") but the result was something a lot more compatible but also with a performance that surprised us and meant we had a new reference level cable.

Although the Graphite and Black Diamond look identical (except for the silver name), when you hear for yourself the Graphite against the new Black Diamonds you will be in no doubt which is which and why we had to release this product - our best work. We are so excited!!! The Graphite speaker cable was referred to as “the best speaker cables I've ever heard” by one reviewer and the Black Diamonds leave our fantastic Graphite range a long way behind in terms of performance and compatibility

“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.”
