“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”
– Wijit Boonchoo, Wave Online
“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.”
