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.
Note: All Tellurium Q Speaker cables can be Bi-wired by adding an extra cable during manufacture.
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 !!!”

“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 !!”

“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”
