Minimal Vibration & Noise

anti micro-phony

To minimize vibration and noise, each RCA connector is sealed with an anti micro-phony compound to damp excess vibration in that part of the signal path. This helps to enhance the silent background in your system.

Where does this cable's performance belong in the Tellurium Q families of sound?

The Silver Diamond RCA Interconnects were developed and designed after the Silver Diamond speaker cable to complement and reveal as much of that “world leading” performance as possible.
Although a relatively new addition to the Tellurium Q cable family matrix has already confirmed it’s position as our reference interconnect cable and will suit systems where detail and a full range, natural sound are important.

“The whole mid/high frequency spectrum unfolds in way that makes you stop and think: what`s going on here? Suddenly there appears to be a huge additional amount of information that was previously hidden somewhere - somehow?!

The real icing on the cake is that all this additional musical information comes served, not in a dry, technical manner but in a highly musical form and this makes the whole thing immensely gratifying.

The recovered details strongly enhance the sonic realism and instruments and voices sound even more natural and believable than one ever thought would be possible. The Tellurium Q Silver Diamond interconnects achieve all this without becoming bright, harsh or annoying in any conceivable way, no, they just sound incredibly natural and relaxed. A big trick in my book!

If you think you know all your recordings pretty well...I dare you to try the Silver Diamonds; you will be absolutely shocked upon discovering what else is hidden in your precious music collections.”

"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."

"This is a sign that we are dealing with something exceptional in the audio world and the cables prove to be really unique."

"By the way, the silver diamond are destroying cables several times more expensive! new order soon..."
- Francisco Moya, Spain

"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

A delighted customer that took the incredible step of getting rid of all his cabling that he had only installed six months previously!!!. This is what he said in a note to our Spanish distributor:

"Paco... I want to thank you that a few months ago you sent me the (Tellurium Q Silver Diamond) cables to test them in my system... and be able to appreciate its qualities!

I liked them.

But now that all my cables are Tellurium [Q] and paired with tubes the result is MAGIC.
The "naturalness" of those cables, a quality that I like so much, together with all the other attributes, offer a sound that is very pleasant to me and get deep into my soul. The realism of each and every instrument is so huge that I've only found something similar in two systems (extremely expensive) from all the auditions that I've done over the time.

It's clear that I've achieved also a synergy among all the components of my sound system... otherwise the sound could be very good, but never be MAGIC.

In the flight case that you sent to me there was only one pair of RCA interconnect. The other pair that my system needs I used a [cable brand name removed] although the sound was very good, it never reached the quality that I have right now, with all Tellurium [Q] cabling."

Regards,
Mario, Spain

The Tellurium Q reference RCA for one very good reason - they are staggeringly good. Detailed and smooth. Nothing in the interconnect range even comes close to this performance.

“If there is such a thing as a completely neutral interconnect, then the Tellurium Q Black Diamond probably fits this description like no other cable.”

“The obvious danger is that the ambitious audiophile will soon want to recable the entire system with Tellurium Q Black Diamond…..Such cables really are the stuff recommendations to close friends are made of”
- Frank Hakopians

“In short, I can honestly say the Tellurium Q Black Diamond interconnects and speaker cable are the very best leads that I have ever had in my system.”

“It seems as if the UB [Ultra Black RCA] has such precision with regards to timing that it gives a presentation which is very different to virtually every cable I've ever heard, no bloom added decay, colouration or drag”
- HiFi Pig, April 2014

“The first few seconds of play were more than enough to realise that Tellurium Q has got a very special design on its hands.”

The Black RCA is thought of very highly by people who try it:

"Black RCA curious change occurred. First, there was a sense that the overall picture is somehow simpler, it slightly diminished shades and tones. In fact, to get the effect "grated window" - the spectrum of nuances become more apparent and clearly.He became more visible contribution to the tweeter, while the explicit emphasis on RF failed.The music became more interesting to listen to."
- Nikolay Efremov, Audio Video

1st out of 17 RCA interconnects in a group test and only cable to have a perfect score in ALL 16 categories:

"Nowhere does the music sound sharp or thin, but very open, transparent, defined. Everything sounds completely balanced. The sound is completely separate from the speakers and we feel as if we ourselves were present at the shooting. The original setting is left untouched and had only experienced by some in this group test such a commitment. So pure, so much momentum and so much peace. This is for us very close to the perfect interlink."

- Harro Tillema, Alpha-Audio

“Putting it into my system, I was impressed by just how communicative this modestly priced cable was. Compared to my favourite similarly-priced cable I had to hand TQ offered a significant improvement in focus, timing and overall lucidity.” - Steve Dickinson, HiFi +

HiFi World Review

“I’d say it sounds one of the very best cables at the price”
- David Price, HiFi World 2011

"Hi Geoff,

I would like to give you some feedback, but not sure where to start. I can only say I am very pleased with the cables, it has opened up my system to an extent I thought impossible and this is with the Black Cables, so not sure how it can be even better with your high end cables.

The best way to describe the change is really that my wife always say "Sounds the same", when we try or listen to some very high end Hifi Equipment, but as soon as I had installed the cables, she said "sounds much better and much more open Music, almost like being in the concert Hall". So this is properly the best way to describe the change.

I am Marine Engineer with Electrical engineering included, so have to admit that I was sceptical of how much a cable could improve the sound, although I do fully understand the importance of screening on low signal cables.

I also want to thank you (Your Company) for the very fast and good reply to queries and also with the customs. I will for sure keep recommending your cables to whoever I meet and have already done so to a few. Thanks to you and I wish you all a Happy New Year and hope 2015 will be a good year for your company."

Best Regards,

- Erik Juul Madsen, Korea

The Blue RCA is our entry level RCA given 4.5 stars for sound quality by HiFi Choice in 2012 because we had designed it specifically to work with our Blue speaker cable not as a stand alone product. This we viewed as a failure on our part so put significant time and resources into developing the Blue RCA further and the new version leaves the old Blue in its wake in terms of performance - we are truly proud of it and hope you will be too.
