Pursuit Perfect System: Black Diamond Speaker Cable

“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.”

Jim Rooney: Black Diamond Speaker Cable

“When I first decided to write to you about your Black Diamond Cables (bi-wired speaker and XLR interconnect) I had accumulated about 100 hours of listening time, but held off because the sound quality kept on improving. Even now after about 300 hours, it’s amazing and hard to believe, the sound keeps improving getting richer, lusher and more resolute as the hours accumulate.

My B&W 802D’s have never been happier, responding much faster than ever before!

I would like to thank you and the design team in Langport for doing such a great job developing the Black Diamond series of cables. Your attention to detail and pushing the state-of-the-art is greatly appreciated!

Good cables do matter!!!!

Thank you”

“As our first overseas client said of these when they changed them for the Graphite speaker cables:

“The cables have arrived and they are simply fantastic!!! More inner resolution and the same time smoooother which is very hard to do in high end. The bass has also more control and the same time better integrated with the rest and all this without burn in!!! Great work !!!”

Tibor Szegedi, Hungary: Black Diamond Speaker Cable

“It is true, these cables are finally perfect. I can connect it to the 15000,-€ Ayon Gyrfalcon or use with the 2000,-€ Amphion Argon 3 and with both I hear the the cables harmonise perfectly with the speakers and shows the strengths of both designs. For me it is no way now to use any other cable for my demos !!”

Mono & Stereo: Black Diamond Speaker Cable

“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: Black Diamond Speaker Cable

“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.”
