Tellurium Q Black Diamond RCA Interconnect
PLEASE NOTE: 1m usually ships next day.
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.
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.
Contact Enhancer Option
To ensure the best possible connection between your system, Future Shop recommends the DeoxIT Gold G-Series contact enhancer.
DeoxIT Gold is carefully applied to the plug contacts of your cable and is a unique conditioning solution designed to improve conductivity and provide long-lasting protection on gold, base metals and other precious metal contacts and connections. DeoxIT Gold penetrates plated surfaces, molecularly bonding to the base metals to seal and protect both surfaces.
The benefits of applying DeoxIT gold are:
- Improved Conductivity
- Maintained optimum signal quality
- Reduced wear & abrasion
- Prevents fretting/dendrite corrosion
- Forms a protective anti-tarnishing coating
- Stabilises connections between similar and dissimilar metals
- Reduces arcing, RFI and intermittent connections
Please select this option from the above ‘Contact Enhancer’ drop-down menu and our engineers will apply the contact solution to your cable connectors prior to shipping.

“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.” Tony Bolton, HiFi World , FEB 2014 edition |
About Tellurium Q 
Tellurium Q cables offer a unique approach to cable performance, focusing on minimising phase distortion, a common problem inherent in all cables. The Tellurium Q team understands that all signal path materials act as electronic filters, impacting the naturalness of vocals and overall audio quality.
Instead of ignoring this issue, Tellurium Q embraces it and engineers cables that provide a clear path for the signal, aiming for the most natural sound possible with current technology. Their construction involves multiple stranded conductors of varying materials, dielectric materials, and geometries. Every detail, from solder mixes to plating thicknesses, is carefully considered.
Tellurium Q has developed three distinct families of sound to cater to different customer preferences: the Tellurium Q Silver range offers silver-like characteristics without harshness, the Tellurium Q Black range (including the Tellurium Q Black Diamond) provides transparent and lifelike reproduction, and the Tellurium Q Blue range adds a slight warmth to balance brighter systems. Each range is designed to enhance the audio experience uniquely. They strive to offer a clear, transparent, and natural listening experience and invite customers to hear the exceptional results of their work for themselves.
Having entered the Hi-Fi scene in 2010, Tellurium Q has won several coveted awards and global recognition. With their extensive range of top-tier cables available in 37 countries, they've accumulated 154 exceptional reviews and 14 'Products of the Year' awards from international Hi-Fi magazines. They have twice received the 'Queen's Award for Enterprise' in recognition of their remarkable export growth. Tellurium Q's uncompromising commitment to excellence ensures its products are not just good or average but exceptional, offering customers the best available in its price range.

Free Premium Cable Burn-In Service: Experience the Power of Nordost VIDAR 2 Machine
We are thrilled to unveil our upgraded cable burn-in service, now featuring the cutting-edge VIDAR 2 burn-in machine. At Future Shop, we strive to provide the best possible experience for our customers, and this enhanced service is designed to unlock the true potential of your high-end cables. Read on to discover the exceptional benefits and advancements offered by the VIDAR 2 machine.
Please note: We are unable to burn-in cables with stripped bare ends or BFA plugs. Cable burn-in occurs after your order has been processed for the selected time period. For custom-length cables, burn-in takes place after termination by the manufacturer or our skilled engineers.
The Nordost VIDAR cable burn-in machine seamlessly combines three vital functions into a single operation:
- Neutralising charges around cables and insulation: The VIDAR 2 effectively dissipates any built-up charges, creating an optimal environment for signal transmission.
- Deep conditioning into the conductor core: With its wide band and profound conditioning capabilities, the machine induces significant changes in signal passage through the metal, resulting in enhanced performance.
- Ultrasonic surface conditioning of conductors: The VIDAR 2 employs ultrasonic technology to refine the conductor surface, further refining the signal quality.
In addition to all the advantages of its predecessor, the VIDAR 2 introduces remarkable improvements, including:
- Complex burn-in signal with wider bandwidth and richer content
- Enhanced directionality for cables
- FOUR burn-in zones - including a new digital zone for USB, Ethernet, and Coaxial (BNC) cables.
Using a proprietary blend of composite and complex signals, the VIDAR 2 ensures comprehensive cable conditioning. The signal consists of ultra-low and ultra-high frequencies, surpassing video frequency ranges. The signal effectively penetrates the core at ultra-low frequencies by oscillating throughout the cable while swiftly traversing the surface at ultra-high frequencies. This transmission methodology counters harmonics and heterodynes between the two complex waveforms, improving signal performance throughout all cable layers.
Furthermore, the circuitry design boasts a unique feature that drives electrons above the conductor into the dielectric or insulation area. This process neutralizes any electrical charges that may impact the signal integrity. With the Nordost VIDAR, we go beyond merely sending ping-pong signals along the cable; we also ensure a balanced signal flow from the centre core to the outer shield in interconnect cables.
What does all this mean for you?
Conditioning your cables with the Nordost VIDAR yields remarkable benefits, including enhanced sound staging, heightened detail reproduction, and a more captivating and musical presentation.
We offer our cable burn-in service as a complimentary offering at the discretion of Future Shop. While we strive to accommodate all burn-in requests for the specified time periods, please understand that during exceptionally busy periods, we may be unable to fulfill all demands due to the limited connections available on the Nordost VIDAR cable conditioning machines.

Excellent cable
Richard
2 Nov 2024
Firstly, I have to commend Mark at Futureshop for sorting out a complete courier mess. He sourced a replacement and burn-in, so I did get my hands on this excellent cable. How problems are dealt with is the mark of a good company.
I started with the Ultra Black II, which I have also reviewed, and this cable is superbly natural and insightful without glare, but it was so good I wanted more, so I took the plunge with the Black Diamond.
It is absolutely an upgrade on the Ultra Black, but it is much more revealing, which can be a double-edged sword if there is any weakness in your chain. I use it to connect my DAC to a Class A headphone amp and Hifiman HE1000SE headphones, and the extra insight exposed a slight glare, which wasn’t present with the Ultra Black. The Diamond had 96 hours of burn-in in so it obviously needed more time and it could have been the Delta/Sigma DAC chips but after some fiddling the power cord to the DAC was identified as the culprit. Cue the insertion of a Tellurium Q Black power cord and QSA fuse, and the problem was solved, at some expense, however, and the sound is sublimely natural.
So, in summary, this is a superb cable, but it may send you down the rabbit hole of further upgrades if there is a weakness that is exposed.

A Superb Cable

I have bought several different Tellurium Q Black Diamond Cables (RCA, XLR, Digital Coax, & Phono RCA). In comparison with other brands of cable I previously owned, I find that there is a noticeable and immediate improvement in the sound quality. Everything sounds more apparent and more focused, a tighter and deeper bass, with less harshness and splashy treble, but without sounding enclosed in any way.
Tellurium Q Black Diamond cables are expensive, but if you have a high-spec HiFi, these cables will help bring out all the qualities you are looking for. I highly recommend them!

Telurium Q Black Diamond Cables are Excellent

Over the years I have slowly replaced all of my interconnects and speaker cables with Tellurium Q Black Diamond. They are expensive, but give me the best sound I have ever had from my system. Think I pretty much have one of each type: Speaker cable, RCA interconnect, Phono interconnect, XLR interconnect and an SPDIF Coax digital cable. I would not use any other now.
I have heard definite improvements over previous cables, after installing the Black Diamonds, with improved h/f detail, better focus, and greater bass clarity and slam. Without making the sound harsh or sibilant. Can't fault any of them, and strongly recommend all of them.
Future Shop offer a free burn-in service, which is worth having. They also send out the items as soon as they are ready, with next day delivery. The delivery company (I think it is DPD) send you a text with a 2 hour window for when they are going to deliver. In my experience, they always arrive early on in that window.
Great cables; great shop; and great delivery! Very happy!

I have tried many cables in my Naim system some far more costly than the TQ black Diamond but none have matched the Black Diamond performance. They offer an enormous degree of detail and clarity but in a very natural unforced way with superb tonality, they also excell at opening up the sound stage. I also have the Black Diamond speaker cables and they are also superior to any other cable I've tried thus far, quite simply they get out the way and let the music flow. My only advice would be unless you are in a position to purchase these cables better not to listen as you will not want to part with them. One other thing to note is they take a while to burn in so give them time and they will reward, Future shop did a 96hrs burn in for me which is worth doing. Absolutely recommended without hesitation they are superb cables.

As I wrote for the Q Black speakers cable, what I love of Q black is its speed. Everything is extremely fast and warm. Also Bass is under control and fast. High tones are solid but not loudly
