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.”

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

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.”

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.

My fave ever
I bought this to travel for a summer camp and still use it, two years later! It is now my everyday jewelry container. The gold clasp has held up well and closes well. Very easy to use and structurally sound! I love the color and overall vibe of it too- very straight forward. I use the top portion for long earrings, so know if you do that, it can be finnicky, if you have fun or funky shaped earrings- so just know they may get caught but it's such an easy fix. I would say it is about the size of half of an American Girl doll. Maybe around the size of half a goose.

Love this! Sturdy and elegant
I have a small selection of jewelry pieces I wear but I needed something that would keep them all together in one place. This jewelry box is fantastic! And It fits two pairs of sunglasses on the bottom compartment. I like that there’s a little tab to help pull up the top part. It was actually a bit bigger than expected which is a good thing. And still small enough for traveling. The necklace tabs are sturdy and hold them in place. I’m very satisfied with my purchase.
