“So what the manufacturer described has worked well – now we get better cables for the same money. How can you argue with this? These days, such things don’t happen often. Rather, the tendency is that you have to pay more and more for worse and worse crap, so any act of reverse action deserves praise. Ultra Blue II is another successful product of this brand, and Tellurium Q may add another award to its extensive collection.”
– Tomasz Karasiński, Stereo Life
“You could spend twice as much and not get as good a sound.”
– HiFi Plus Awards Edition 2025
“This cable is fabulous.
The first thing that struck me was the extension and amount of the low frequencies. This draws a more complete and consistent stage. There is a tremendous amount of different shades together with an excellent precision of all bass sounds.
One can discover many more details throughout the whole stage. This stage is wider and especially much more deep. All this gives an excellent separation and placement of instruments. Voices now come from 3 dimensional faces.
Tones struck by instruments decay in the room until the very last end I definitely need such a cable.”
– Roland Dumont, Luxemburg
“This is a sign that we are dealing with something exceptional in the audio world and the cables prove to be really unique.”
– Wojciech Pacuła, highfidelity.pl
“I was impressed by the way the Tellurium Q cables seemed to approach transients (both leading and trailing edge) and cohere the sound of the music temporally. Although I am not sure how a digital cable can influence the timing of a musical signal, it’s clear through audition that the Tellurium Q cables do just that.”
– Nicholas Ripley, HiFi Plus
“Thought I would drop you a little follow up… I have really been enjoying the Ultra Black ii rca cables… For me they have been an eye (ear) opener to what good cables can do!
I have since acquired a pair of Ultra Black ii speaker cables… again wow! These are a great step on from the [removed] I was previously using.
I have not heard my system sound so refined yet full of detail… and feel… I find myself being drawn into the music much more easily.”
– Paul Stemp, UK
“Its performance is rather remarkable, especially its openness and freedom from smear that bedevils most “starter” level cables. Its sound has has an outstanding clarity and focus, along with a fine transparency and, hence a very natural character on vocals .. Its inclusion in my office system has certainly brightened my working days. Allowing me to hear even more of the music that was previously struggling to reach the speakers.”
– Malcolm Steward, The HiFi Journal
“The character of the speaker cables is distinctly pacy; this is very much a rhythm-oriented cable, where timing is given top billing regardless of the music being played. And this makes it very engaging and powerful; my foot started tapping of its own accord and I found myself swept up with the groove on all manner of tracks.”“Tellurium Q Ultra Black II is a remarkably coherent and “well-timed” cable.”
– Jason Kennedy, HiFi Plus
“I think this cable makes the amplifier and speakers show the highest performance without any colour. One of the best and dynamic details I’ve ever heard.”
– Dawn Nathong, What HiFi Thailand
“Although by no means a newcomer, Tellurium Q’s chief engineer Geoff Merrigan continues to work his magic trick of improving upon that which had previously seemed beyond criticism. The top of the range Statement series of cables has garnered a fistful awards both here in the UK and around the audio world. I was able to compare those original Statement interconnects in both RCA and XLR configurations with the next-generation mkII versions, and was taken aback at the overall improvement in sound quality that I witnessed. More of everything came through the loudspeakers: airier treble, punchier bass of course but above all more of what we are all pursuing in this hobby, pure musical pleasure.”
– The Ear Best of 2023
“Just a short compliment for your products and a general remark. My new black 2 loudspeaker cables perform very nice indeed. Thanks you for a great product.
I used the enhancement Cd for burn in and was pleasantly surprised by its effect and the reduction of burn in time required. Intrigued, I then used IT for a Day or two on several headphones I’ve been using for several months to several years. Each of those sounded clearly more relaxed, spacious and made for more fatigue free listening afterwards.
I know it’s not your core business, but perhaps you could spread the word to your consumers that they could try the same.”
– Rudi Spigt, Nijmegen, the Netherlands
“I went ahead and ordered Black II XLR’s RCA and power cable and already I’m speechless, they really are something!”
– Dave Matthews
“Whatever you do, don’t audition the Ultra Black. As I said before, once you do, there’s no going back.”
– Steve Dickenson, HiFi Plus, Awards Issue 2010
“I have to say that the Silver II speaker cables have made an astonishing improvement in my system. I’m using a pair of Omega single-driver speakers (95 dB efficient) with an ancient (22 years old) Linn Majik Integrated amp. The Silver II really lets the subtle tonal shading and inner detail that the Majik is capable of shine through. In addition, the improvement in clarity and tonality of the bass has cured my desire for a subwoofer.
Thanks for developing such a wonderful product!”
– Ron Gordon, USA
“The added resolution, ‘rightness’ and musical truth they impart, while besting cables costing far more than their price point, is your reward for not needing to read specs.”
– Stereo Times, Most Wanted Components Award 2015
“Clear and very transparent. Especially the details. That’s “amazing”, is very remarkable in every way, the more I listened the more I love it.”
– What HiFi, Thailand
“For me, Silver Diamond series signal cable is one of the most impressive products of the year. It conveys details very realistically and giving a natural, clean sound with full power. Significantly, it maintains tonal balance and the phase is more accurate than some signal cables that are almost twice more expensive than this cable.”
– Wijit Boonchoo, Wave Online
“Changing over from the [company reference deleted] cable to this [Tellurium Q Black II] even without the ‘burn in’ made a big difference to my system straight away , never known such a simple upgrade make such an improvement.”
– Mark Buffey, UK
“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.”
– HiFi World, Awards Edition Jan 2015
“Two further swaps between the two sets of cables and I had heard enough to know that once again Tellurium Q had delivered on their stated intention, to take the good things about the Silver IIs and make them even better…
I know it is still only April, but I think I have just found one of my Products Of The Year: Bravo Geoff, mission accomplished.”
– Jason Kennedy, The Ear
“I hear from readers from time to time, who remain convinced that when I write about cables I am confusing different with better. I envy them in some ways, because they will save themselves a small fortune by sticking to whatever choices they made when assembling their systems. Unfortunately I hear not only differences but improvements with some cable changes and I can only report that in all honesty, the Tellurium Q Ultra Silver IIs are the best loudspeaker cables I have yet encountered in my own system.
These weeks with Ultra Silver IIs have been an absolute treat, and have shown me how much more I could get from my existing components if I could make this upgrade permanent.”
– Chris Kelly, The Ear
“…so far I’ve gotten the Black interconnects for my CD player, the Black II speaker cables, and now I await the TQ jumpers to put my Klipsch LaScala H and Lo together. The speaker cables sounded great out of the box BUT WOW a month later indescribably clear, crazy holographic. I’m using the Raven Audio Nighthawk Integrated Amp, Yamaha S2100 CD player, and U-Turn Orbit turntable with Ortofon Blue. What really shocked me was how LP’s sounded way better than the CD’s (which sounded great too). But the vinyl improvement was shocking. How can we get the word out? These things are totally amazing. The improvement with your cables equal or exceeded ANY component upgrade I’ve ever made.”
– Don Childs, USA
“I am absolutely impressed by Power Ultra Silver. It sounds very clear with crystal pure sound like 3D. Perfect job! We’ve made an experiment: we’ve changed in AC Line-conditioner power cord Black to Silver Diamond. And it was wow-effect: OMG it’s like absolutely new more-more expensive system, fantastic!”
– Dmitry Vorobiev, CEO of ATEM, Russia
