Tellurium Q® Reviews

Looking for something specific? Type a cable name like Silver Diamond, a cable type such as an RCA cable, or combine them — Silver Diamond RCA Cable. You can even search by reviewer, e.g. Tone Audio.

“Silver III represents both a significant leap forward in performance over Silver II and lends itself to more upmarket equipment partnerships. So, significant in fact that Tellurium Q decided a matching set of interconnects werein order.

Having checked several of the latest generation of Tellurium Q cables against their predecessors, this seems to be a common theme; the cables are improving across the board, and they are also allowing more high-end performance. But perhaps more importantly, they do this beyond the direct comparison with TQ’s existing cable range.

Tellurium Q Silver III is one of those easy recommendations. At its price, it’s hard to beat for overall value. It takes what made Silver II so popular and adds so much more.”

“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.”

“One of those OMG moments!….
Every now and again we try a new bit of kit to see if we can improve on our already capable top end system. Little by little we push the bar higher, but every now and then something very significant comes along.

KOG audio told us about a new Tellurium Q cable that goes from the DIN output socket on a record deck to a couple of RCA (Phono) plugs. Part of their Statement range, at an eye watering £3600, we thought we’d try one to see if it justified its price tag.

Plugging it into our smart new Technics SL1000R direct drive record deck (not to be confused by previous models of the SP10 / SL1000 – this is a whole new ball game), via a Lehmann Audio Decade pre-amp, into the 500 series Naim system with the gorgeous Focal Scala Utopia speakers. It took about 5 seconds to realise it had transformed the whole system into something so special, I haven’t heard anything as good, anywhere, at any time, for any price !”

“So it is refreshing to happen upon a set of cables that can deliver the sonic goods, yet don’t cost as much as a small island.”

“After playing one track with the same volume before and after playing the Track Three on the Tellurium Q short system wake up the music comes out more vivid, more open and more room than it was before. It’s a big difference before and after and definitely the easiest way to enhance your system of playing or reproducing music on your system and by the way the most cost effective way of enhancing your system.”

“Two days ago I bought 2.5 meter long tellurium q black speaker cables. I am very happy: Transparency, detailed no harshness. I never heard music so well in 26 years .

Bravo !”

“Immediately on connecting them up I noticed how clear and detailed they sounded in comparison to my previous cables, complimenting the rest of the system very nicely indeed. My Audio Physic Avanti’s have exceptional imaging capabilities and with these cables in place I was given an even more three dimensional image. Integration from the very top the very lowest frequencies was seamless with a lovely open mid-range that benefited vocals and acoustic instruments. It’s the tiny details and intricacies that make the difference for me when I listen to recordings I think I know inside out and suddenly hear new things and here these details I certainly did with the Ultra Blacks in place.”

“I tested the difference between the balanced analogue cables first and the first big difference I noticed was in the early moments of Liberty by Annette Askvig, there was silence between the passages of the music, but with the Statement I there was never any silence. So, for me, the Statement II gives a much blacker background or a greater noise rejection and lower noise floor. This goes hand in hand with the improved edge definition, clarity, improved spatiality or sound stage and three dimensionality.”

“In its own price point, The Ultra Blue II mains cables are giant killers. I’ve heard more expensive mains cables which occupy that general price bracket which are very capable indeed, more expensive but don’t reach the same sonic heights.”

“I was immediately struck by how much the Tellurium Q [Silver Diamond ] seemed to lower the noise floor. Notes emerged from a much quieter background – the Clocks at the Pink Floyd’s “Time” were startlingly striking. If you want to hear the full musical range of your digital files then it is a must.”

“Geoff wasn’t really expecting to get any commercial success from the onset of developing the Silver III. He and his team used it just as a challenging project to find out what else they could learn about signal propagation. What they have achieved with the Silver III is something quite extraordinary. A very detailed and wide soundstage capturing all frequencies evenly, and with fast transients to give the music the bite it deserves
They bring the highest level of the TQ 3×3 matrix to those with the smallest pockets.”

– Janine Elliot, HiFi Pig

“It is even possible that this is the most absent-in-the-path speaker cable I have ever encountered.

The British interconnect introduces practically no modifications in terms of tonal balance or sound timbre, and its presence in the system is revealed only by such aspects as microdynamics, transparency, speed and – once again – a wonderful, three-dimensional, perfectly organized space in which each source is clearly defined, has sharp shapes and is, one might say, firmly anchored in its place. In my opinion, the neutrality and stereophony of the Tellurium Q flagships are beyond question.

The cables somehow magically interact with each other, enhancing each other’s best features and improving the sound quality much more efficiently than when we check them separately.

And this is what makes Statement II the perfect, dream, and destination cable for many audiophiles. This is a dream come true and soothes the senses for those who are looking only for the truth about music, and for whom all other high-end cables were “too bad” – bringing many benefits, at the same time, they interfered too much with the sound. In other words, the search is over, at least when it comes to cabling.

If you have a suitably advanced system and you have changed cables many times, each time gaining something and losing something else, and at some point you started to wonder how such a set would sound with cables that are not there, which are inaudible, completely transparent, the solution to this puzzle is it’s waiting right here.”

“If you’re looking for a major jump in your system’s performance, I’d suggest buying a pair of these instead of considering a hardware upgrade. Before you write this advice off to cable delusion, expectation bias, or the recent Mercury retrograde phase, please take note: I have never said this in TONE’s 11-year history. Value is a highly relative subject; cable is nearly always a hotspot and I admit to being more prejudiced against spending big money on it, yet the Tellurium Q Silver Diamond speaker cables deliver more music than anything I’ve yet experienced. I highly suggest auditioning them the next time you’re considering spending some money on a system upgrade.”

“Having inaugurated an awards season for 2022, it seemed appropriate to acknowledge some key pieces of HiFi equipment that have passed through HF&MS over the preceding nine years. There have been just three ‘Night and Day’ moments over this period. These experiences are usually unexpected and simply tangible, where you just think; ‘blimey, this is really really good!

I was one of those who appreciated cables were important but I had no idea how profound the introduction of a medium to high-end cable could be and the Ultra Black II is by no means Tellurium Q’s best cable.”

“Tellurium Q Blue II offers a fantastic and great value upgrade for those looking for good sounding and well put together loudspeaker and interconnect cables. They have a balanced and pleasing sound to them that allows you to enjoy the music without wanting to dissect it or feel that you are missing anything. They are still in the system if that is any indication.”

“The first serious meeting with Tellurium Q products turned out to be unexpectedly interesting. An English company is considered a phenomenon, its products are said to be doing well against any competition, and several industry colleagues use them in their work.I talked to Geoff several times and he gave the impression of a man who is 100% sure what his products are doing. More than once, he announced it to everyone and to him in a completely unforced way, as if it were an obvious truth. Now I know why. He just knows it from the inside and is not surprised.

Tellurium Q Silver Diamond hf is on many planes clearly better, capable of alterations that are beyond the reach of the product of the native operation.”

“If you have the original Tellurium Q Ultra Black then this update might take you aback. It doesn’t just improve on the original it takes the sound on in leaps and bounds…… I heard the same effect on every track I played – leading me to believe that there is something special going on with these Ultra Black IIs….Tellurium Q’s Ultra Black II’s can be see as one of the best loudspeaker cables on the market at their price.”

“What on Earth did Tellurium Q do to make the music much more moving?… finally I have to admit the magic power of Statement [II].

After switching to the speaker and signal lines [XLR] of the Statement II, I replayed this album again. My wife suddenly asked me what I had changed (she was used to the test of playing acoustic equipment at home). She said that those songs were better than before… Oh!! If I have the financial resources, I should leave the Statement II.”After switching to the speaker and signal lines [XLR] of the Statement II, I replayed this album again.
