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”

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.

Best no-show socks ever!
Size: 6-10, Color: Black
If you're tired of wearing socks that slip off and show in your sneakers, then you need to try these amazing socks! They are designed to stay in place, even after being active all day. They are incredibly soft and comfortable, and they are truly no-show, so you won't see them at all. I've been using these socks for years and have never had any issues. In fact, I love them so much that I've bought multiple packs, and my family members have started using them too. Don't waste any more time with those annoying socks that slip off and show - give these a try and you won't be disappointed!

The best
Size: 9-11, Color: Black
Seriously the best non slip low cut socks you can find. They stay in place all day and I love the fabric. They are thin which I prefer. These are really the only socks I wear.

Great socks for the price!
Size: 6-10, Color: Black, Size: 6-10, Color: Black
I love these socks, they are perfect no shows but the material is thick enough for toes not too go thru. The grip is perfect and keeps the sock in place all day. I would definitely order true to size as the fit was perfect. I was surprised to find these socks at the price I did, especially when I got the socks in both black and white.

Best non-slip no show sock!
Size: 6-10, Color: Black
I love these socks! I wear them mostly with my slip on vans. The are thin so your feet can breathe (I hate thick socks). They have a grip on the heal so that they don't slip off of your feet, and it actually works! My only negative about these socks would be that if you have bigger than a size 8 foot, I would not purchase them because they do run a bit small. I wear a size 7 and they fit perfectly! They do look very tiny upon unpacking, but they stretch to the according size. I would also recommend letting them air dry after washing them and not putting them in the dryer. The first pair I purchased, I made the mistake of drying them and they shrank to an unbelievably small size. I've had my second set of socks for over 4 months now and have not had any problems since Ive been air drying them. I have not encountered any problems with them tearing as other have stated. Even though these are thin socks, they seem to be made quite well in my opinion.

I buy these again and again through the years!
Size: Medium, Color: Austin Brown Assorted (6-pairs)
Love these. After a year or two I wear holes in the bottoms because I wear them so much. Worth the little bit higher price because of the fit and comfort. Love how they are truly no show
