Description

SD-RCA

Silver Diamond RCA Cable

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.

Performance Profile

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.

“I think this cable makes the amplifier and speakers show the highest performance without any color. One of the best and dynamic details I’ve ever heard.”

Mono & Stereo

“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.”

Tone Audio

“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

Stereo Times

“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

Mario Tantra

“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

Mario

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

Why Choose Tellurium Q

Tellurium Q is a British high-end cable manufacturer that has built a global reputation for producing cables designed around one core principle — preserving timing, coherence, and the natural structure of music. Rather than focusing purely on conductor materials or exaggerated “Hi-Fi effects”, Tellurium Q approaches cable design through extensive listening and phase-focused engineering, resulting in products that consistently improve musical flow, tonal balance, and system realism.

At HeyNow Hi-Fi, Tellurium Q has become one of the most successful and consistently recommended cable brands, particularly the highly regarded Black II series. One of the major strengths of the brand is how effectively the cables work together as complete looms throughout a system. Customers often begin with a single interconnect or speaker cable before progressively expanding through the range, discovering how consistency across the loom can significantly improve coherence, tonal balance, imaging, and overall musical flow.

The Black II range in particular has proven remarkably successful because it delivers genuine refinement and naturalness without pushing systems into sounding overly warm, bright, or analytical. As customers move further through the Tellurium Q range into Ultra Black and beyond, the presentation becomes increasingly open, dimensional, and revealing while still maintaining the musical ease and listening comfort the brand is known for. This scalability and system-wide synergy is one of the reasons Tellurium Q continues to receive worldwide industry recognition and strong long-term customer loyalty.

Signature Design and Sound

Manufactured in the United Kingdom, Tellurium Q products are developed using proprietary design methodologies centred around signal timing and phase behaviour. The company deliberately keeps many technical aspects confidential, preferring listeners to judge performance through listening rather than marketing specifications alone.

Sonically, Tellurium Q cables are known for their smoothness, coherence, and highly natural presentation. The sound feels organised and relaxed, with excellent tonal density and a remarkable ability to reduce glare and harshness without sacrificing detail retrieval or openness. Vocals become more believable and focused, instruments carry greater texture and separation, and the soundstage often feels deeper and more stable.

One of the defining strengths of Tellurium Q is the way complete looms allow systems to sound more unified and musically convincing. Rather than drawing attention to individual sonic traits, the cables work together to improve flow, timing, and realism across the entire presentation.

Tellurium Q Product Range

The Tellurium Q range includes speaker cables, RCA and XLR interconnects, digital cables, USB cables, Ethernet cables, and power cables across multiple performance tiers. Popular ranges including Black II, Ultra Black II, Silver, and Statement allow customers to progressively refine and scale system performance while maintaining consistency throughout the cable loom.

The Black II series remains one of the most respected and widely recommended ranges within high-end Hi-Fi thanks to its exceptional balance of musicality, refinement, and value. Higher-level ranges including Ultra Black and Silver introduce greater transparency, spatial realism, and low-level detail retrieval for customers seeking additional performance from increasingly capable systems.

For listeners seeking cable solutions that prioritise coherence, realism, and long-term listening satisfaction, Tellurium Q remains one of the most successful and musically rewarding cable brands in contemporary high-end audio.
