Silver Diamond Speaker Cable

The Silver Diamond are the cables that we were not sure could be made (although we hoped they would be possible). If you read through the “Our Focus” section on the website, we talk about the fact that any cable from any manufacturer is an electronic filter, whether you want it to be or not – that is just a fact of life. Being a filter, any cable causes relative phase relationship issues for the signal. We have taken our research and development that was outlined in “Our Focus” and just tried to push the concept of a neutral filter as far as we thought it was possible to give you a highly transparent, natural and “real” presentation.

So what’s different? Well, compared to the Black Diamond, which was our award winning multi-product of the year cable, the Silver Diamond has even better bass definition, improved detail and a more extended top end (without any harshness) and something else which people are finding hard to define, simply because they have not heard it before. As one of the first people to hear the cable said, there is a “certain rightness” to the sound and that is because we have got closer to achieving our goal in cable development and have signal transmission than ever before, and you can hear it. Perhaps an analogy would be to talk about the Black Diamond as HD image quality, whereas the Silver Diamond gives you 4K Ultra HD quality with 3D effortlessly thrown in for good measure.

This cable behaves differently to our others, needing a run through of track three from our System disc to properly embed it, before listening on a new system even when it is run in – almost like conditioning the system to make the most of the cable’s abilities. It may sound a bit strange that a system needs to be tuned up or put in tune to get the most from this cable, but the cable is something quite unique as you will hear if you get the chance to listen to a system using it.

We are very proud to have this cable finally crowning our ranges.

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.

Reviews and User Comments

“The cables are amazing… it makes the FOCAL sound much better. The harshness of the Beryllium is much more controllable. The bass is more dynamic, full and tight. The staging is wide … even the speaker position is close.”

– Mario Tantra, MDI Audio, Indonesia

“Should you be a cable skeptic, this is the one to try. The results are not subtle, with no change in tonality or balance. Just more music everywhere is the word. The Silver Diamond cables impart less of a sonic signature than so many other, so much more expensive cables we’ve tried. Every cable skeptic we know has been bowled over by the Silver Diamond cables.”

– Tone Audio, Awards 2016

“…the Silver Diamond cable is a unique cable….It is a whole set of cables that gives the most “natural” sound, which is an outstanding feature that impresses me. Other outstanding features are both dynamic The extension range in the light. Giving a soft sound to listen to Indulge in a deep sense of music. Access to the realism of the sounds from each musical instrument, airy, clean, at a level In our lives we rarely meet”

“I was so impressed by what the Silver Diamond was doing with the bass – among other things, of course – that I started sifting through my music collection seeking out the best bass content…..To conclude, I’d have to reinforce how impressed I was, and how much I enjoyed, having the Tellurium Q Silver Diamond in the system. It is balanced, natural, and neutral and draws the best from your electronics and speakers…Nailed it.”

– Edgar Kramer, Sound Stage

“The Silver Diamond speaker cables offered a tremendous tonal realism, clarity and detail combined with a naturalistic flow. You don’t feel that music is bumping its head on any unnatural music boundaries which means there is less subconscious tension around the soundstage and that relaxation I mentioned flows in abundance. You feel that you could listen to your music for hours (and hours).The Silver Diamond standard should arrive with a government warning, it’s dangerously easy to listen to these cables.”

– Paul Rigby, The Audiophile Man

“A euphoric power will liberate freedom, according to the music. Listen, and then feel special, pleasing for this generation of silver diamond cable”

– Audiophile Videophile

“Tellurium Q Silver Diamond is a product of the audio sphere, which can easily demolish all our current assumptions on how a speaker cable should or should not “play”. The above statement is perhaps trivial, but it is justifiable and strongly related to what we hear just after the first contact with this cable, and even what we build assumptions based on the information obtained. Its impact on the sound is very clear and you do not have to attentively listen to the system for a prolonged period of time, as the differences are clear just after the first contact with this cable.”

– HiFi HiEnd Test

“These are the best cables I have used in my system… period… and I do not say that lightly! They have been in and out and compared with other cables we have to hand and every time they are taken out there’s an immediate “nope, get them back in” comment from Linette or myself. What they do is difficult to put your finger on exactly; there’s a feeling of rightness and a sense that you are getting closer to the feeling of the music in an emotional sense. There’s more detail, more space…and they just sound right.”

– Stuart Smith, HiFi Pig

“The [Silver Diamond] cable change has brought an elevation in every aspect of the listening pleasure. They cost quite a sum of money, but what they offer; to even a small system such as this is, is arguably worth every penny they do part you with.I knew they were good, but what I didn’t know is that it can make something great, sound astonishingly real.”

– Tony Pothitos, Hiend News

“They [Tellurium Q] focus on Silver Diamond’s ability to act as less of a filter than most cables, and that this performance is particularly well suited toward high-end systems. When the cables are used in that context, asserts Alan Sircom, “Silver Diamond is extraordinary transparent, satisfyingly open, full-bodied, with an awesome bass, and extremely sweet and smooth across the mid-range.”
